Audi Service and Repair Redwood City - What to look for when buying an Audi A4 - Bosch European Redwood City



audi a4


When buying a used car it is essential to know what to look for. Used Audi A4's are not exempt since they are expensive cars that need care and attention. With care and attention, and Audi will return the favor by being a very reliable car with timeless looks. In this article we will be discussing what to look for when looking at 1996-2001 Audi A4’s. This model is often referred to as simply B5. The two most important questions that buyers should ask themselves are: “Do I need a six cylinder or a four cylinder?” and “Should I settle for a front-wheel drive car, or should I get an all-wheel drive?”

Do I need a six cylinder or a four cylinder?
The main differences between the two are gas consumption and reliability. With the six cylinder B5 Audi you will have a choice of two engines. The earlier models (1996 and 1997) come with a twelve valve (or two per cylinder) engine. These are known for being the most reliable without needing the most attention. The drawbacks to this specific engine are that it is slow and does not have much of a modification market. In other words, if you want a “fast” car, don’t buy a 12V. The other engine is the one that came with the later B5’s. This engine is known as the 30V V6 (five valves per cylinder). This engine is still a very reliable engine. The 30V has extensive backing by aftermarket communities.
The other available engine is the 1.8 Turbocharged. This engine was offered from 1997-2001. This is the most popular engine chosen by drivers that want modify their cars. Many people replace the original turbocharger with a bigger turbo (referred to as BT among Audi communities). By doing this, these cars can have double and even triple the original power. With everything good, bad comes. These are known as the least reliable engine for the B5 since they need the most attention. This engine is “unreliable” because many people do not treat them as they should. These engines need maintenance to be on point. This engine is prone to engine sludge if owners do not change the oil every five thousand miles with synthetic oil. However, if the engine is kept up to date with proper maintenance, the car will be as reliable, if not more than a 12V B5.

Should I settle for a front-wheel drive car, or should I get an all-wheel drive car?
Front-wheel drive cars are much cheaper and have better fuel economy, but they have trouble driving in the snow or bad weather. All-wheel drive Audi’s have Quattro which is one of the best AWD systems made for cars. Through Quattro, any Audi will handle much better than their front-wheel drive counterpart. Along with this resale values among Quattro cars are much higher than those among front-wheel drive cars.

When looking at any used Audi A4's there are pointers to keep in mind:
- Make sure the owner has actual records for the service that has been done.
- Check that the car has had major maintenance done at the recommended time interval. For B5’s timing belts are the most important since they can cause the engine to fail if they break (~80,000 miles). For 1.8T’s, oil changes are also very important (~5,000 miles).
- Look for rust, or any body parts that have been replaced or repaired.
- Make sure you enjoy the car. If you feel that it does not feel as it should, take it to a mechanic.

BMW Service and Repair Redwood City - BMW offers history lesson on 40 years of electric vehicle efforts - Bosch European Redwood City


BMW's all-electric 1972 1602




If nothing else, we can thank BMW for giving us the rare opportunity to post a picture of one of its classic, super-boxy '70s models. In this case, it's an electrified version of its 1602, the progenitor to the popular 2002. The 1602 was the German automaker's first foray into electric-vehicle production, and the company made two of them to ferry officials for the 1972 Munich Summer Olympic Games around. The cars had a single-charge range of just 37 miles.

BMW continued extremely small-scale testing of various EVs until 2008, when it produced about 600 of its
Mini E electric vehicles for testing in both Europe and the US. BMW remains on schedule to start selling its i3 all-electric vehicle starting late next year. That model is the successor to the ActiveE coupe, which was the model that came after the Mini E.

Lately, the automaker has promoting its zero-emissions efforts pretty hard, complete with a
"Born Electric" tour. Last month, BMW unveiled a coupe concept version of the i3 just before the Los Angeles Auto Show, complete with a carbon fiber body and an electric motor that puts out 170 horsepower and 184 pound-feet of torque.

Lexus ES300 Service and Repair Redwood City - Lexus ES300: history and description - Bosch European Redwood City




Lexus ES300: history and description


The Lexus ES sedan set a value standard in entry-level luxury when it arrived in 1990, and continued to set the pace in its 1992 redesign (when it went from being the ES250 to the ES300). The ES was re-engineered in 1997, received a new powertrain (with the same engine displacement) for model-year 1999, and updated again in 2000; the ES330 appeared afterwards, with the ES350 arriving in 2007 

A perennial winner of quality awards from J.D. Power and Associates and "Best Value" awards from Intellichoice, the Lexus ES 300 was given a more sporty appearance in 2000, with a new grill featuring a wider chrome frame and two bars instead of three, with a chrome finish. Designers gave the the front bumper a more "chiseled" design, and the integrated foglamps now used clear lenses. New optional High-Intensity Discharge (HID) headlights gave greater road lighting and lend the ES 300 a different look in front. Redesigned tail lamps used clear lenses, while an ES 300 badge was put onto the right-side light.

More important, the optional Lexus Vehicle Skid Control (VSC) system, introduced in 1999, was expanded to include the advanced Brake Assist feature in 2000. VSC helps maintain traction under demanding conditions by detecting and helping to correct for wheel slip. Brake Assist interprets a quick, hard push of the brake pedal as emergency braking and, if the driver has not stepped hard enough on the brake pedal to activate the anti-lock brake system (ABS), Brake Assist supplements the applied braking pressure.

In 2000, the separate remote lock fob was replaced by an on-key remote button, and new stainless-steel doorsill scuff plates with the Lexus logo were added; additional wood trim surrounding the audio and climate controls augmented the genuine California walnut trim on the center console and doors. New, more-recessed rear-seat headrests improved rearward visibility for the driver, and a lock for the standard trunk pass-through was added; 16 inch alloy wheels with 205/60 tires were made optional. Auto-dimming interior and driver's side rear-view mirrors became standard equipment, and the optional heated seats were given two temperature settings; and the optional driver's power seat memory included the outside mirror settings.

The standard audio system added Automatic Sound Level (ASL), which adjusts volume up or down in response to ambient noise. Specially tinted window and moonroof glass rejected ultraviolet and infrared light to help keep the interior cool on sunny days and to protect interior materials from premature aging, and a dust/particle filter was made part of the leather trim package.

The ES350 advanced the state of the art with the new Lexus 3.5 liter V6, pushing out 272 horsepower and 254 lb-ft of torque in 2007, while still increasing gas mileage thanks partly to dual variable valve technology (working on both intake and exhaust valves) with variable lift; the system, along with a six-speed automatic transmission, helped the ES350 to get from 0-60 in 6.8 seconds while still getting Camry-like gas mileage (21 city, 30 highway).

Lexus ES 300 performance and brief review (2000)

The aluminum 3.0-liter double-overhead cam V6 engine produced 210 horsepower and 220 lb.-ft of peak torque (about the same as the IS300), allowing for a sprint from 0-60 mph in just 8.3 seconds, good for the time in an automatic-transmission car. Perhaps more important, the engine produced 80 percent of its peak torque - 176 lb.ft. - at a very low 1,600 rpm, which enhanced performance in everyday situations, such as freeway merging or driving up a steep grade with a full load of passengers. Gas mileage is 19 city, 26 highway, rather good for a luxury sedan.

A three-stage variable intake system and a two-way bypass exhaust system optimize breathing and help boost torque in the ES 300 engine. Continuously variable valve timing optimizes valve overlap throughout the engine's speed range and in all operating conditions, eliminating the traditional compromise between low-end torque and high-rpm horsepower. The Lexus VVT-i (Variable Valve Timing - intelligent) system also helps to optimize fuel efficiency, and it helps to reduce emissions to the point that the engine does not require exhaust gas recirculation. The ES 300 is certified as a Low Emissions Vehicle (LEV).

The electronic four-speed automatic transmission provides an outstanding balance of smooth shifting and quick response to make best use of the engine's torque curve. The transmission avoids unnecessary upshifting and downshifting to create a smooth ride.

The ES 300 is completely silent and still at idle, helping the stereo to sound clear and strong even at low levels. Part of the reason is a solenoid-controlled diaphragm which cancels out the engine's vibration; there is also considerable noise insulation. While the ES 300 does not feel fun and exciting under full acceleration because of this, it does feel remarkably civilized under just about any conditions.

The ride is soft without being wallowy, soaking up imperfections but still transmitting some road feel and not giving up any control; there's no big trick in seeing how Lexus leapfrogged Lincoln and Cadillac, not to mention Mercedes.

High-intensity discharge headlights are optional; they give a blue tint, which hurts other drivers’ vision by scattering the light, but they do provide considerably more light than standard halogens. Tail-lights are now clear, following a fashion trend, and the ignition key includes the remote fob, saving some keyring space. The interior has more of a luxury feel thanks to extra wood trim, new rear seat-rests, automatic-dimming rear view mirrors, and a lock for the trunk pass-through. An optional automatic climate control particle filter is a worthwhile boon not only to people with allergies, but to anyone who drives in a dirty, dusty environment - which is most of us.

Standard features include antilock brakes, automatic climate control, a tool kit and first aid kit, power driver and passenger seats, remote locking, cruise control, and traction control.

Advanced Lexus safety features

The ES 300 helps protect its occupants with an array of safety technology, starting with front and rear energy-managing crumple-zone body construction and a strong passenger compartment. Inside, the ES 300 has three-point seatbelts for all five seating positions as well as dual front airbag and front seat-mounted side airbag Supplemental Restraint Systems. The front seatbelts feature pretensioners, force limiters and height-adjustable anchors. New child restraint seat (CRS) top tether brackets comply with the phase-in of the CRS Anchorage Point Regulation.

Standard safety technology includes electronic traction control (TRAC), anti-lock brakes (ABS) and daytime running lights.

Lexus ES300 construction

While luxurious amenities abound in the ES 300, its luxury "feel" actually starts with a tight unibody structure that integrates extensive measures to reduce noise, vibration and harshness (NVH). A construction technique shared with the LS 400 flagship sedan, the ES 300 employs asphalt dampening sheets in the roof, rear quarter panels, floorpan and trunk lining, along with steel-resin-steel sandwich construction in the dashboard, cowl, front floor tunnel and rear wheel housings.

Four-wheel independent suspension mounted in the subframes gives the ES 300 a luxuriously smooth ride and precision, fun-to-drive handling. For an even smoother and more responsive ride, the ES 300 offers an optional Adaptive Variable Suspension system (AVS).

This innovative system - uncommon in this segment - continuously changes each wheel's shock absorber damping rate in response to road surface conditions, vehicle speed, driver steering and braking input and even vertical vehicle movement. AVS also permits the driver to select the desired range of ride character from "sport" to "comfort."

While renowned for the smoothness of its engines, Lexus found a way to eliminate even the smallest vibrations in the ES 300. An industry-first active engine mount uses a solenoid-controlled diaphragm to produce pulses equal-but-opposite to those of the engine, canceling out vibration with every power stroke.

Mercedes E Class Service and Repair Redwood City - Mercedes-Benz E-Class History - Bosch European Redwood City






With the E-Class entrenched in North America as a luxury machine, it can be a little disconcerting to see that it is used as a taxicab in much of the rest of the world. Mercedes' reputation wasn't built on plush fittings and heavily chromed decoration, it was earned by cars that could survive for decades pounding over dirt roads or broken pavement, or forming a line drawn by rival militias lobbing grenades at each other. Mercedes cars are tough, and that's what made them worth extra money even when they didn't offer overt power or luxury.

While the E-Class' ancestry stretches back to the 19th century and the beginning of Mercedes, the lineage becomes more distinct after World War II when the prewar 170 sedan reentered production. The stout 170 had been Mercedes' most popular model before the war, but the design dated all the way back to 1936; and in 1946 its upright stance, separate fenders and running boards and chassis were archaic. Fortunately for Mercedes in the immediate post-war years, the few buyers there were in Europe weren't in any position to be picky.

It's the 170's replacement, the first "modern" Mercedes, which started the company on the path toward today's E-Class.

The Ponton (W120: 1953-1962)

The 1953 Mercedes 180 was the company's announcement that it could build and compete in the world's contemporary automotive market. With bulbous fenders integrated into its body design, the W120 (its name inside Mercedes) was the company's first car to feature the "envelope" styling that was the defining element of modern post-war design (the '49 Ford helped establish the style). Those bulbous fenders also gave rise to the 180's nickname: the "Pontoon" or, the German spelling, "Ponton" Mercedes.

Also unlike previous Mercedes, the W120's body was actually part of the car's structure, though it wasn't quite yet what would be considered a "unibody" today. The front of the car consisted of a separate subframe to which was bolted a double-wishbone independent front suspension. The rear suspension used the wicked swing arm system with which Mercedes was infatuated at the time.

The big advantage of the Ponton body style was that it was exceptionally large inside for a car of only modest size on the outside (the original 1953 180's 104.3-inch wheelbase and 176-inch overall length are nearly identical to those of a 2003 Honda Civic). But what held that first 180 back was the engine; a 1.8-liter four scavenged from the old 170 model with an L-head, a 6.5-to-1 compression ratio and an output of just 52 horsepower. Stirring the column-shifted four-speed manual transmission for all it was worth, the 2,700-pound 180 had performance between slow and agonizingly slow. And if agonizingly slow wasn't slow enough, in 1954 buyers could get the 180D, powered by a 1.8-liter diesel four rated at only 40 horsepower.

W120s may have been slow, but they were wonderfully rugged. European and developing countries would soon adopt the car (particularly the diesel) as their taxicab of choice. Even today, a full 50 years after the W120 was introduced, they're still used as taxis in countries like Syria.

For 1955, Mercedes put the 190SL roadster into production, basing most of its chassis and running gear on the W120. But the 190SL also introduced a new overhead cam, 1.9-liter four. This thoroughly modern (by 1950s standards) power plant made a credible 120 horsepower while breathing through two carburetors in the roadster, and it was inevitable that it would find its way into the sedan. In 1956, it made that migration and the 190 sedan was born with 75 horsepower available through its single carburetor 1.9-liter four. In '57 the 180 also got a version of the new engine, this time rated at 65 horsepower. Then, in October 1958, a dieselized version of the 190 power plant was introduced in the new 190D, making 50 horsepower. Finally for the 1959 model year, a 190b model was introduced that got 90 horsepower from its four.

Outwardly, there were few differences among the W120s that accounted for an astounding 62 percent of Mercedes' production during its run. Their intrinsic solidity made them so important in building Mercedes' reputation for quality, not their rakish lack of style. By the beginning of the 1960s, the W120 was exhausted.

The Fintail (W110: 1961-1968)

Mercedes usually didn't lower itself to following automotive fashion trends. But in 1961, it introduced a new midsize model with…tail fins. Just like a Plymouth or Cadillac. It was also virtually indistinguishable (except for size) from its larger Mercedes sedan brother (which was almost six inches longer).

It's those small tail fins that gave the new W110 sedans their nickname "Fintail." But the fins aren't the major contribution of the W110 to the E-Class legacy. The really important developments included on the W110 were front disc brakes, an automatic transmission and a six-cylinder engine.

Other than the fins, the W110 differed from the Ponton car it replaced by being just over nine inches longer and over two inches wider overall. The hood was shorter than the Ponton's, however, and that left much of the car's extra length in the tail where it resulted in an enormous trunk. Inside, the W110 was exceptionally roomy for its still modest size, and the dashboard notably featured a tall pod directly in front of the driver outfitted with thermometer-style instrumentation (imagine a speedometer that fills up like a fund-raising drive's poster as the car's speed increases).

Under the skin, the W110 carried over the basic suspension and chassis design of the old W120. The front end was still supported by double wishbones, while the rear suspension still consisted of swing axles now blessed with a horizontal spring to help compensate for differences in side-to-side weight distribution.

The W110 hit the market in '61 as 190 and 190D models (sold alongside some versions of the W120 through '62), carrying over the gasoline-fired 80-horsepower, 1.9-liter four and the 2.0-liter diesel four. In '62 an automatic transmission (a semiautomatic four-speed unit) was offered on the 190 for the first time.

For the 1965 model year, the 190's engine grew to 2.0 liters and output snaked up to a full 95 horsepower and the name changed to 200 (the diesel, which already had a 2.0-liter engine, became the 200D). But the big (literally) news was the availability of six-cylinder power for the first time in a midsize Mercedes with the introduction of the 105-horsepower 230. The 2.3-liter OHC six used in the 230 was familiar from the larger 230S sedan, and slightly detuned for use in the smaller W110. Besides the extra power, the 230 distinguished itself with new headlight assemblies that combined the turn signals and headlights into one unit capping the front fenders. Four-cylinder 200 models continued to carry separate round headlights.

Like the Ponton model before it, the small Fintail (as opposed to the larger "S" Fintail) was easily the most popular car in the Mercedes line, accounting for 59 percent of total production. And the ruggedness and economy of the diesel version made it a hugely popular cab around the world. But by 1968, after 622,453 Fintails, it was time for a new car.

The Stroke-8 (W114/W115: 1968-1976)

With its antiseptically clean and simple styling, the 1968 W114/W115 looks contemporary and elegant even in the 21st century. And with the replacement of that archaic swing axle rear suspension with a new trailing arm, fully independent system, it finally had a suspension worthy of a Mercedes.

The W114/W115 (the W114 was a six-cylinder model, the W115 had fours) was a wholly new midsize Mercedes expanded to include models with four-, five- and six-cylinder engines. In fact, there were times during the model's life that up to 15 separate models existed inside the midsize Mercedes family, including a two-door variant. The "Stroke-8" name arose when it was necessary to distinguish the new car from the old Fintail that continued in production during 1968 and carried the same model names. During '68, a 200D was likely a Fintail, while a 200D/8 was definitely a W115. Even after the Fintail was gone, that Stroke-8 heritage persisted in the informal world of nicknames.

A lower hood line led to a wider, lower grille shell on the Stroke-8 models, while thinner pillars and a two-inch longer wheelbase than the Fintail gave the cabin an open, airy feel. But despite the wheelbase stretch, the Stroke-8's 184.5-inch overall length was actually two inches shorter than the car it replaced. Further, thanks to a robust unibody structure and new safety equipment like a padded dash, the Stroke-8 weighed in about 300 pounds heavier than its predecessor.

The Stroke-8's chassis was truly new and the engines initially powering it were familiar but, at least in North America, not identical. The base four over here grew to 2.2 liters and output swelled to 116 horsepower and, naturally, the car was named the 220. The 230 continued with the 2.3-liter six, but output had by now grown to 135 horsepower. A new 2.5-liter version of the six appeared in (there's a pattern here) a new 250 sedan as well and that engine produced 146 horsepower.

The coupe arrived during the 1970 model year as the 250C ("C" for, you guessed it, coupe) sitting on the same wheelbase as the sedan, but about two inches lower in overall height. And while it was called the 250C, it didn't actually carry the 2.5-liter six. Instead it had a 2.8-liter version of the six aboard making 157 horsepower. In 1971, the 250 sedan was blessed with the 2.8-liter engine.

Both the coupe and sedan were slightly redesigned for 1973 getting an updated front end, new fluted tail lamps and bigger bumpers to meet U.S. Federal regulations. More significant was a new 2.8-liter, DOHC straight six under the hoods of the newly named 280 and 280C. With emissions regulations getting tougher, engine outputs were dropping everywhere, so the new engine's 130-horsepower output was actually quite respectable. Also, for the first time, an automatic transmission was standard with the six-cylinder Stroke-8s.

In 1974, the four-cylinder engine was upgraded to 2.3 liters and 95 horsepower so the car (then Mercedes' cheapest for sale in America) was renamed the 230. A new 2.4-liter diesel four was also available in the 240D rated at 62 horsepower. The big diesel news came in'75 however, when Mercedes grafted another cylinder to the new diesel four to create a 3.0-liter straight five diesel making 77 horsepower — at the time, the most power available in a diesel passenger car.

On the gasoline-fueled side of the equation, 1975 brought with it the first use of catalytic converters. That clog in the exhaust system only robbed the 230's four of two horsepower (down to 93), but the 280's six retreated a full 10 horsepower to 120.

The Stroke-8 was wildly popular, with Mercedes building 1,833,442 of them before ending production during 1976. That's a stunning 77 percent of all Mercedes passenger-car production during that time. It would be a tough act to follow.

The Wedge (W123: 1977-1985)

With a slight rake to its stance, the new W123 (on sale in Europe during 1976 and a 1977model in America) was undeniably a Mercedes of the 1970s. With a flattened grille, horizontally oriented headlamps and sculptured sides, it looked, more or less, like a scaled-down version of the era's 450SEL.

Under the new skin were some significant advances in safety (moving the fuel tank over the rear axle where it was better protected in a collision, for instance), but the biggest change came in the engine bay of the six-cylinder model where fuel injection appeared for the first time on the smaller Mercedes. Accordingly, the letter "E" for "einspritz" (German for "injection") appeared as part of this model's name, 280E.

While the W123's wheelbase grew to a full 110 inches (up from the Stroke-8's 108.3), overall length was down in the U.S. thanks to an improved bumper system (European W123s were actually slightly longer than European Stroke-8s). That again meant even more room inside the cabin that, like the exterior, was styled along the lines of the big S-Class.

The last midsize Mercedes powered by a four-cylinder gas engine to be sold in the U.S. appeared as the 230 sedan in '77. Breathing through a single-barrel carburetor, the 2.3-liter four in the 230 could only muster 86 horsepower and came standard with a manual transmission. From '78 on, the cheapest W123 would be the diesel 240D, whose four-cylinder engine clattered out 62 horsepower. The five-cylinder 300D also continued to be offered with a power rating of 77 horsepower.

It was the fuel injection atop the 280E's 2.8-liter, DOHC straight six that radically improved the drivability of the new W123. With 142 horsepower available, the '77 280E sedan was no high-velocity rocket ship, but the engine was flexible and friendly in its power delivery.

The 1978 model year brought forth new 280CE and 300CD coupes, and in '79, a new 300TD station wagon arrived. All were built on the same 110-inch wheelbase as the sedan, though the coupes were about 1.5 inches lower overall. The wagon offered a third-row seat as an option. In the late '70s, mired as the era was in serial fuel crises, the economical diesel was appreciated by most buyers.

Innovations that would become regular equipment on future Mercedes models appeared during the W123's life. The 1980model year brought a four-speed fully automatic gearbox, and antilock brakes were available for the first time. In '81, a driver-side front airbag made its first appearance.

Surprisingly, Mercedes eliminated the gasoline-fueled W123s from the American market after 1981 and instead installed the 120-horsepower turbodiesel five from the S-Class in the 300D. And that's how the W123 played out its days in America.

Mercedes built a total of 2,375,440 W123s, including 199,517 wagons.

The E Name Arrives (W124): 1986-1995

The most important thing about the W124 is that it was conceived and designed by Mercedes after the company's introduction of the smaller 190-Series (what would eventually become the C-Class) for 1984. That, for the first time, meant the company was selling passenger cars smaller than the E's progenitors — the midsize Mercedes was now actually in the middle of the range.

Everything about the new Mercedes W124 was new and everything about it looked new — more 1990s than mid-1980s. The structure was completely revised and, through the use of high-strength steel and other construction methods, was significantly stiffer and lighter. The front suspension still utilized double wishbones but incorporated anti-dive technology; and the rear suspension was now a multilink system, which rode better and improved wheel location throughout its travel. The front grille sloped back for better aerodynamics and there was but a single windshield wiper that, using an eccentric cam, was able to clear that big piece of steeply raked glass all by itself. Even the engines were new. In the history of Mercedes sedans, there's never been one more completely revised than the 1986 300E and 300D.

Slightly narrower than the W123, but sitting on a somewhat longer wheelbase, the W124 weighed in about 200 pounds lighter than its forebear. Power for the gasoline-fired 300E came from a new 3.0-liter, SOHC, 12-valve straight six making 177 horsepower, while a new 148-horsepower, 3.0-liter turbodiesel straight six motivated the 300D. Both models came with a four-speed automatic as the standard transmission.

Because the 190 attracted bargain shoppers, the W124 took a notable step up in price and standard luxuries. A driver-side front airbag, antilock brakes, central power locking, power windows, headlamp washers, an alarm system and dozens of other items, which were once options on this class of Mercedes, were now standard.

For 1987, a 260E sedan joined the W124 model mix in the U.S., powered by a 2.6-liter version of the 300E's straight six rated at 158 horsepower. Also new that year was a station wagon that came only in 300TD turbodiesel form.

The 1988 model lineup included a new, crisply styled 300CE coupe, and a five-speed manual transmission was now offered on 260E and 300E. Considering that just a few years earlier diesels had made up over three-quarters of all Mercedes sold in the United States, the disappearance of diesels from Mercedes' 1988 lineup may have been a surprise. But increasingly severe particulate emissions standards left the company little choice. This also meant that Mercedes was finally selling a gasoline-powered wagon here as a 300TE.

The 1989 model range was virtually unchanged except that the five-speed manual transmission (few of which were ordered anyhow) was gone from the lineup again and a passenger-side front airbag was a new option.

A diesel returned to the 1990 W124 line with the introduction of an all-new 2.5-liter turbocharged inline five aboard the awkwardly named 300D 2.5. The 260E was also inelegantly renamed the 300E 2.6 for no apparent reason. By stealing the DOHC, 24-valve cylinder head from that year's new 300SL roadster, the 300CE's 3.0-liter straight six now made a healthy 217 horsepower. Beyond that, if you wanted Mercedes' 4Matic all-wheel-drive system on your 300E sedan or 300TE wagon, you could get it.

For fans of traction control, 1991 was a big year as Mercedes' ASR system became optional on the 300E, 300TE and 300CE.

Much bigger news came with the 1992 models and the introduction of V8 power to the midsize Mercedes. The new, mainstream 400E sedan had the 268-horsepower, 4.2-liter, DOHC V8 from the larger S-Class sedan under its hood. Meanwhile, the glorious limited-production Porsche-built 500E was also introduced with the 500SL's 5.0-liter, DOHC V8 between its specially flared fenders. With 322 horsepower on board, the 500E was easily the most powerful midsize Mercedes ever and the quickest sedan of any size the company had ever built.

Dual front airbags were standard across Mercedes' 1993 line and new engines were installed in the W124. The 300E 2.6 became the 300E 2.8 as the engine grew to 2.8 liters and now wore a DOHC head with four valves per cylinder. And all 300E "3.0" models (except the wagon and 4Matic sedan) had their 3.0-liter engines upgraded. Now at 3.2 liters and sporting DOHC, 24-valve architecture, this engine produced 217 horsepower. This year also saw the debut of the 300CE Cabriolet.

Finally for 1994, the E-Class officially came to be, as Mercedes reengineered its naming system by putting the "E" before the number and rationalizing the numbers in line with displacement. So the returning lineup consisted of E320 sedan, wagon and coupe, E420 sedan and E500 sedan. We guess "E" no longer stood for "einspritz." To celebrate their new name, the W124s got new grilles, headlights and taillights for '94. At midyear, an E300D diesel arrived with a normally aspirated 3.0-liter straight six making 134 horsepower. Also, the 4Matic versions were dropped this year.

With a new E-Class due for '96, the only substantial change to the '95 line was the elimination of the limited-production E500. After 2,212,025 W124s, Mercedes was ready for a new E-Class.

The Four-Eyed E (W210): 1996-2002

With four elliptical headlamps, the 1996 E-Class (W210) set the styling trend for Mercedes models into the 21st century. Underneath the dramatic new aerodynamic skin, the wheelbase grew 1.3 inches over the W124's and overall length was up 2.2 inches. The engineering itself was rather familiar. There were still double wishbones doing the suspension work up front, and a multilink system holding up the rear.

For '96, the new W210 E-Class models offered in the U.S. were the E320 with the 3.2-liter, DOHC six from the outgoing W124 making 217 horsepower, and the E300D with the carryover 3.0-liter diesel six. The W124 E320 coupe and convertible carried over for the time being.

In the middle of the '96 model year, the E420 sedan reappeared with the 4.2-liter V8 (making 275 horsepower) hooked up to a five-speed automatic transmission.

The 1997 model year saw the introduction of a new driver-adaptive five-speed automatic for the E320 and E300D. Additionally, Mercedes added a sport package to the options list for the E420 — included within it were 17-inch wheels and Z-rated tires, foglights and various cosmetic touches. All models got a smart sensor that could detect the presence of a front passenger and decide whether or not to deploy the airbag in a crash.

Major changes to the W210 for '98 began with a new 3.2-liter, SOHC, three-valve V6 replacing the former straight six in the E320, the station wagon body returning as an E320 and the E300D gaining a turbocharger and intercooler. The boosted diesel was impressive with a 30-percent increase in horsepower and a massive 57-percent increase in torque. Beyond all that, the 4Matic all-wheel-drive system was back as an option.

A new side curtain airbag system came with the 1999 E-Class, but the more enticing development was the new AMG-engineered E55 sport sedan. Using a hand-assembled 5.4-liter version of the SOHC, three-valve V8, the E55 was engorged with 349 horsepower. It was fast and gorgeous hunkered over its 18-inch AMG wheels, and it was the most expensive E-Class ever. Also this year, the E420 became the E430, as its V8 was a new 4.3-liter mill, though output was unchanged.

The diesel disappeared again as the 2000 model year started and the "Touch Shift" system (that added a manual-shifting scheme to the five-speed automatic gearbox) debuted. A revised front end and interior appeared in '02 as well.

With a new E on the way, 2001 and 2002 were relatively quiet years for the car. But you could get a new sport package for the E320 that included lower body cladding and larger wheels and tires.

The Current E (W211): 2003

Building on themes established by its immediate predecessor, the current E-Class arrived in the U.S. for 2003 more voluptuous than the W210, proudly displaying Mercedes' new styling direction. The E320 received the now familiar 3.2-liter, SOHC V6 making 221 horsepower, while the new E500's 5.0-liter, SOHC, 24-valve V8 knocks out 302 horsepower. It is also the first E-Class since 1985 to have two windshield wipers. Among the interesting new features on the W210 generation are electronically controlled brakes, an adaptive suspension (standard on the E500, optional on the E320) that continually adjusts spring and damper rates for the benefit of ride quality and handling, four-zone climate control and optional Drive Dynamic seats that alter cushioning in response to cornering forces.

For 2004, a new station wagon comes, 4Matic is back and the E55 sedan returns with a supercharger atop its 5.4-liter V8 to produce a walloping 469 horsepower. That's nine times as much as that first Ponton 180 in 1953.

BMW Service and Repair Redwood City - BMW 7-Series History - Bosch European Redwood City

 BMW 7 Series (E65/E66) 735i (2001 - 2005)

 
The BMW 7-Series is a large luxury sedan that's well into its fourth decade of production. Introduced in 1977 with its "7-Series" moniker, the car was preceded in mission by a large six-cylinder sedan built from the 1960s to 1977. Today's 7-Series is the most expensive sedan sold by BMW, and its most powerful--not counting the Rolls-Royce lineup, which BMW acquired in the late 1990s. The 7-Series comes in six-, eight-, twelve-, and eight-cylinder hybrid versions, and competes against the Audi A8, Jaguar XJ, and the Mercedes-Benz S Class in the business-luxury segment.

The first 7-Series was introduced in 1977, and was sold through the 1986 model year. A large, roomy four-door, the "7er" came to America in three versions: 733i, 735i, and L7. The U.S. versions were outfitted with power features, leather and wood trim, and a sunroof, as well as bigger bumpers, and marketed as luxurious competitors to the most expensive Mercedes four-doors. Some versions of the European-market, turbocharged 745i were sold in the U.S. in the grey market--technically not illegal but not imported by BMW itself. The L7 was a version of the 735i fitted with more leather trim and more standard features, as well as an automatic transmission and a driver-side airbag--making it the first vehicle sold in America with that safety feature.

With the second-generation 7-Series, which was sold from 1987 to 1994, BMW added a new engine variant. The 730i sported a 3.0-liter in-line six; the 735i carried on with its 3.5-liter in-line six; and the new 750i arrived with a 300-horsepower V-12 under its hood. The new sedan's styling was more sleek and yet still dynamic, with the quintessential BMW twin-kidney grille tilted forward at the front and inside, a functional--almost austere--cockpit that still featured a manual gearbox on some versions. An "L" version added length to the wheelbase, and late in life the 7-Series gained a new 3.0-liter in-line six and a 4.0-liter V-8.

In the third generation, which ran from 1994 to 2001, BMW watered down the car's styling to near-anonymity. The six-cylinder engine was discontinued, leaving behind a 740i and a 740Li model with a 4.0-liter V-8 (later upgraded to 4.4 liters) and the V-12-powered 750Li. A five-speed automatic was featured, and some mild facelifts accompanied the car through the end of its model run in 2001. This 7-Series also made a start turn, in the 1997 James Bond film,Tomorrow Never Dies.

The fourth-generation 7-Series changed dramatically, and with that change came controversy. This 7-Series, sold from 2002 to 2008, brought with it a radically "flame-surfaced" style that was said to have been a response by chief designer Chris Bangle to a BMW board demand that their cars become more expressive. Expressive they were, but critics contended the high roofline, big glass areas, and oddly tiered styling didn't work well, and disrupted the company's focus on "ultimate driving machines." BMW would go on to sell more of this generation 7-Series than any before, but sales grew thanks to expansion in new markets, particularly China. Over its lifespan, this generation would include short- and long-wheelbase variants, rear- and all-wheel-drive versions, but no manual-gearbox versions.

Perhaps the most disliked feature of the new 7-Series was iDrive. BMW pioneered the round controller on the center console, and intended it to take the place of dozens of buttons and switches in its cockpits. iDrive proved difficult for many users to master, even with haptic feedback and a large LCD screen for navigation. Changing radio stations could be an exercise in frustration; even redundant voice controls for the car's navigation system proved to be a hurdle. Widespread dissatisfaction with both the car's styling and iDrive didn't temper enthusiasm for its handling nor for its brisk acceleration, however. In 2006 BMW uprated the V-8 engine to 4.8 liters and 360 horsepower, and changed the car's nomenclature to 750i / 750Li. It had boosted the V-12 to 6.0 liters and 438 hp in 2004, making it the 760Li. In 2007 it reintroduced an Alpina B7 with the 4.4-liter V-8, without output rated at 500 hp.

In 2009, BMW introduced the current version of the 7-Series. With a revamped look that greatly muted the prior car's humps and crests, the new car turned out much more attractive, particularly inside, where iDrive lost the battle to control every function, and the dash was clarified into a more logical, handsome piece. The iDrive system itself received an entirely rethought, more logical action, with intuitive icons, plus more redundant buttons that "bookmarked" settings for audio, climate, and navigation--whatever the driver's preference. Performance came from a range of V-8 engines for the first model year, with a six-speed automatic the norm in the 750i and long-wheelbase 750Li; in the 2010 model year, BMW added six- and twelve-cylinder (735 and 760) versions, as well as a hybrid teamed with lithium-ion batteries, and new all-wheel-drive versions--and wait, there's also a new Alpina edition. The V-12 version brought with it a new eight-speed automatic transmission, which is expected to make its way through the lineup in due course. A bulletproof version can be ordered, and BMW has long experimented with hydrogen-powered 7-Series sedans--though none has been offered for sale.

Porsche Boxster Service and Repair Redwood City - The mid engined Porsche Boxster 1997 to 2005 - Bosch European Redwood City




 Porsche Boxster 3.2S picture 2000
 

 The Porsche Boxster has an incomparable balance and natural agility. The flat six motor, with its weight low down is mounted in the middle of the car for perfect balance.

There is no 'bad' year to buy. 1997- 2004. The earliest cars would be from late 1996 (1997 model year) and these will be 2.5. From late 1999 (2000 model) the Porsche Boxster 2.7 replaced the 2.5 giving a little more horsepower and noticeably more torque in the midrange. If on a budget for a tiptronic Porsche Boxster it’s worth looking at the 2.7.

Also for the 2000 model year a large engined Porsche Boxster 3.2 S was introduced. These are super sports cars with a 6 speed manual gearbox or tiptronic. They have bigger brakes, stiffer suspension and 250 hp.

These models are known as the 986 series and ran until the launch of the newer shape 987 Porsche Boxster, introduced in late 2004. The only significant change to the 986 series was in 2003 when Porsche replaced the plastic window of the soft top with a heated glass window. This is known as a facelift although it was mild and only changes in the plastic bumpers and molding distinguish these. 

I have used all the models, used them for everything; shopping, for track days, commuting, back road fun and trans European dash's, and they have never failed to impress.

A Porsche Boxster is a proper sports car. Its a fun drive, highly capable, very practical and ever inch a Porsche.

Find out much more by clicking through to the next page link at the bottom of this page.

For the 2005 model year Porsche re launched the Boxster, almost every detail of changed. Known as the 987 series. Learn more about the 987.

If you can afford a decent used Porsche Boxster then don't wait, don't miss out, these are great cars to own and nowadays can be purchased for little more than a miserable hatchback. Do it.
 
Boxster inside view

We live in a world where exciting new developments are being announced all the time, though the reality often turns out to be a relatively modest step forward.
All the more reason to believe that a very special group of people will be particularly pleased to hear that Porsche, one of the most exclusive carmakers in the world, has produced a new model.
It’s an open two-seater with a 6-cylinder, horizontally-opposed engine (boxer) mounted between the front and rear axles. It has 2 luggage compartments. It’s called the Boxster (Boxster and Roadster).
There are mass-produced roadsters, and there’s the Boxster. That really says it all.
The Boxster didn’t come off the shelf. Some companies might take a limousine engine and maybe an existing under body or axle assembly and simply come up with a novel way of putting them together. The Boxster, on the other hand, was developed from scratch as a completely new car. Its design is not based on a search for synergy, nor is it a computer product. It was born in the imagination and passion of a small group of people.
It’s all new, from the first design sketch to the last bolt. That’s why it arouses something which is increasingly rare in our digitised and rationalised world: emotion.

Porsche Service and Repair Redwood City - Porsche 911 996 1998 - 2003 model years.- Bosch European Redwood City




Porsche 911 996 1998 - 2003 model years.

The Porsche 996 is the current '911' series. Porsche introduced the 996 for the 1998 model series starting August 1997.

996 models include; Porsche 996 Carrera 2, Carrera 4, available with both 6 speed manual and tiprtonic gearbox's. Body styles started with the Coupe (see picture of a '98 series 996 C2 manual I owned) and Cabriolet, but recently a 'glass roof' Targa has been introduced, similar to the previous 993 Targa.

picture left is a 996 C2 coupe in ocean blue with 18" Turbo wheels.

 picture of Porsche 996 C2 Coupe in ocean blue.


Also included in the model lineup is the 4 wheel drive 996Turbo Coupe - again manual or tiptronic, plus the limited edition stripped out 996 GT2 and the 996 GT3 race car.

The 996 was a totally new car, with a new shape, a new interior and a new water cooled engine. All previous 911 had been air cooled, a system that has advantages in simplicity and weight, but critically was no longer  viable to engineer to current legislation. Along with the air-cooling went part of the glorious flat six sound. And that's what upset some critics.

The motor, as it's always been, is in the rear, the chassis a development of things learned from the 993 and from Porsche racing activities. Therefore this new model handles even better, has superb brakes, and great performance. The motor was downsized from 3600cc to 3400 cc, although horse power went up (on normally aspirated versions) from 285 to 300hp.

No doubt as time passes the so called 'purists' that consider all 911 should be air cooled will warm to the 996 and appreciate the developments that the Porsche engineers have provided.

The body shape still resembles any earlier 911, but everything has changed. You can feel that the individual panels are less heavy than before, but this is progress and the engineers at Porsche always move forward.

picture left is a 2002 996 Convertible in Orient red metallic.

 Porsche 996 in orange metallic.

 

Open the driver’s door and you will see beautiful cabin architecture.  Gone completely is the practical but idiosyncratic design that had evolved little from the '60's. Instead a roomier cabin, still two plus two, very good seats and a more relaxed driving environment.

Typically Porsche, these cars are efficient and strong, characteristics that have always been evident in all 911 - making the description 'an everyday supercar' just as relevant today as it’s always been.

Lexus Service and Repair Redwood City - Lexus ES300 Problems - Bosch European Redwood City




 

 

Lexus ES300 Problems

Check engine light due to failed oxygen sensor
Model Years Affected: 1992 – 2003
Average Mileage: 141,547 mi (16,584 mi - 248,000 mi)

The Check Engine Light may illuminate because a component of the oxygen sensor stops working. As a result the engine computer is unable to determine the proper ratio of air to fuel for the engine. Replacing the failed oxygen sensor should correct this concern.

Excess engine oil consumption
Model Years Affected: 1992 -2003
Engine Affected: 3.0L V6
Average Mileage: 140,111 mi (74,556 mi - 279,000 mi)

Sludge can build up in the engine because Lexus did not recommend frequent enough oil changes. Lexus will sometimes offer a discount on cleaning the engine if necessary. Owners who changed their oil every 3,000 miles did not experience these problems. This sludge build up can lead to excessive oil consumption.

Misfire and/or check engine light due to failed ignition coil
Model Years Affected: 1992 -2003
Average Mileage: 129,975 mi (101,500 mi - 154,400 mi)

On higher mileage vehicles, an engine misfire may develop and/or the Check Engine Light may illuminate due to a failed ignition coil. It is not uncommon to replace all the coils when the first one fails in order to prevent return trips to the repair shop.

Check engine light and lack of power due to failed mass air flow sensor
Model Years Affected: 1992 -2003
Average Mileage: 121,000 mi (89,000 mi - 161,000 mi)

The Check Engine Light may illuminate because the mass air flow sensor sends incorrect information to the engine control computer. This can cause a loss of power on acceleration. A failed mass air flow sensor will require replacement.

Check engine light due to failed EVAP purge control valve
Model Years Affected: 1992 -2003
Average Mileage: 122,000 mi (121,000 mi - 123,000 mi)
Intermittent failure of a purge control valve in the evaporative emission system can cause the Check Engine Light to illuminate. A failed valve should be replaced to correct this problem.

Mercedes Repair and Service Redwood City - Mercedes-Benz E430 Problems - Bosch European Redwood City





Mercedes-Benz E430 Problems

One or More Instrument Cluster Display May Fail
Affected: 1998, 1999, 2000, 2001, 2002
Average Mileage: 94,500 mi (58,000 mi - 150,000 mi)

Instrument cluster displays tend to fail, especially the clock and gear indicators. Our technicians tell us the instrument cluster will require replacement to correct this issue.

Crank no Start due to Failed Crankshaft Position Sensor
Model Years Affected: 1998, 1999, 2000, 2001, 2002
Average Mileage: 140,675 mi (120,000 mi - 183,000 mi)

The crankshaft position sensor may fail. Symptoms of this are: The engine will crank—but not start—especially when the engine is warm. The car may start again if it is left to cool off, but it may run roughly or have poor performance.

The Differential may develop Leaks from the seals or cover
Model Years Affected: 1998, 1999, 2000, 2001, 2002
Average Mileage: 125,448 mi (89,000 mi - 157,345 mi)

Leaks may develop from the differential cover and/or seals on high mileage or older vehicles. Our technicians recommend a complete reseal of the differential unit if these leaks are addressed.

Squeak in steering column due to rubber boot or seal
Affected: 1998, 1999, 2000, 2001, 2002
Average Mileage: 104,000 mi (60,000 mi - 152,000 mi)

A squeak from the steering column is often related to a rubber boot in the column or a seal in the power steering rack.

Erratic HVAC blower motor operation
Model Years Affected: 1998, 1999, 2000, 2001, 2002

A malfunctioning HVAC blower motor regulator can cause the blower motor to operate below the requested speed or not at all. Updated regulators are available; the blower motor and cover need to be replaced at the same time to upgrade the system.
