I've just had a 118i back - was the oil cooler gasket which is sandwiched between the filter housing and block (I sound like I know what I'm talking about but I don't) 1 Share this post Link to post Share on other sites
idanito 98 0 Posted February 18, 2019 BMW 3 Series (E46) The BMW E46 is an entry-level luxury car which was produced by BMW from 1998 to 2006. It was introduced in May 1998 in the sedan body style. In 1999, a coupé and touring body style became available to all markets, and the sedan was released in the United States. A convertible and hatchback body style was released in 2000, the latter only for Europe, South Africa, Australia and New Zealand. The sedan and Touring were facelifted at the end of 2001. The BMW E90 replaced the E46 sedans in late 2004, however the E46 coupe and convertible body styles remained in production until 2006. All-wheel drive ("xDrive") was re-introduced in the 3 Series, after a break of 18 years. It was available for the six-cylinder 325xi and 330xi sedan/wagon models. The E46 was considered the performance benchmark of its class and experienced success in many markets. The record selling year for the E46 chassis was 2002, when 561,249 vehicles were sold worldwide. The main competitors during the E46's production run were the Alfa Romeo 156, Audi A4, Lexus IS/Toyota Altezza, Mercedes-Benz C-Class, Saab 9-3 and the Volvo S60. The M3 version of the E46 was powered by the BMW S54 straight-six engine. The M3 was released in 2001 and was available in coupé and convertible body styles. The transmissions available were a 6-speed manual or the 6-speed "SMG-II" sequential manual gearbox. Design Exterior design The E46 was developed as an evolutionary replacement for the BMW E36 chassis. In 1995, the general exterior design of the E46 by Erik Goplen was approved and as a result DesignworksUSA was contracted by BMW to work alongside BMW Group's in-house design team to create the exterior body work for the 3-Series range in February 1996.[9][10] Based on the E36 body shell, the design team put an emphasis on improving aerodynamics and increasing the car's aggressive stance. Design patents were filed in Germany on July 16, 1997 and in the US on January 16, 1998. While the styling of the E46 was seen as an evolution of the extremely successful previous generation 3-series, it was not immediately embraced by either the buying public, or the automotive press. Word leaked out in the press that the BMW stylists were unhappy in raising the roof-line, and the general "rounding" of the body panels in comparison to the more squarish E36 series. Chris Bangle was responsible through January 1996 for the production saloon exterior, as evident in the 1997 design patent. Production development of the saloon took 24 months from January 1996 to January 1998. Goplen designed the production coupé and estate during 1996–1997. دانشگاه بدون کنکور Interior design Since the production had started, the entire in-car entertainment system (Radio Function, Navigation System, Television and Telecommunications systems) is based on a very flexible automotive computer system. As a result, the E46 models can all be easily upgraded with the newest BMW technologies including BMW's Bluetooth System, the DVD based Navigation system, as well as BMW's CD changers that play MP3s Weight and rigidity goals An emphasis was put on reducing unsprung weight and increasing structural rigidity rather than increasing power output: the highest displacement model at release, the E46 328, had only 3 horsepower more than the E36 328.To counter this small power increase, the body shell of the E46 was claimed by BMW to be 70% more rigid than the E36's, and aluminium suspension components were used increasingly in order to decrease unsprung weight.[15] However, with a curb weight of 1450 kg,the E46 328ci is 55 kilograms (121 lb) heavier than the E36 equivalent. In tune with BMW's core values,[20] the E46 was released with a front engined rear-wheel drive layout with 50/50 weight distribution. This balance allows for optimal handling in regard to the drive train layout. E46/5 hatchback Main article: BMW E46/5 The hatchback version was marketed as the BMW 3 Series Compact. SULEV BMW introduced a super ultra low emission vehicle (SULEV) into the selected regions of the United States to meet stricter emission standards. California, New York, and Massachusetts received the SULEV E46's in 2003, and Vermont in 2004. They received a variant of the M54 engine, the BMW M56.[22] The M56 meets SULEV standards, as well as partial zero emission vehicle (PZEV) and zero evaporative emissions requirements. The M56 is claimed to have identical power as its M54 counterpart. Share this post Link to post Share on other sites
