Audi A4 B6 Engine's Tendency Towards Electronic Glitches
Based on the Volkswagen Group's B6 platform, the new A4 debuted in the year 2000. A4's new styling was inspired by the Audi A6, but it claimed huge success. Most of the petrol engines; either had a power upgrade or the displacement increased, but the base model's 1.6-liter engine remained intact. There were two versions of 1.8-liter turbo with 20-valve engines available; a 148bhp and a 178bhp, these engines come with standard six-speed manual gearbox. The naturally aspirated 1.8-liter inline 4-cylinder and a 2.8-liter V6 engines were replaced by the 2.0-liter and a 3.0-liter all-aluminum engine with 217bhp and 300Nm of torque.
The 1.9-liter TDI engine had an upgrade and received 128bhp and Pumpe Duse technology and permanent quattro all-wheel drive, whereas the 2.5-liter V6 TDI received 178bhp and quattro as a standard. Rear to front dynamic torque distribution ratio was of 50:50 in this generation, it also was equipped with Bosch ESP 5.7 system, brake assist, anti-lock braking system and electronic brake-force distribution. In year 2002 the 1.8-liter TDI engines received a power upgrade; a 148bhp engine became 161bhp, and a 178bhp engine became 187bhp engine. All of these engines were available with quattro. There was a 2.0-liter engine which was available with Fuel Startified Injection (FSI).
Audi took a huge step a year later and reintroduced Audi Avant S4, only this time it was powered by a monstrous 4.2-litre V8 engine with 339bhp, and A4 Cabriolet convertible, this time it replaced the 1998 discontinued Audi Cabriolet. It featured and electro-hydraulic operated roof which can be lowered within 30 seconds, and the lower bumpers and sills were also body-colored giving it a new style. Audi has the honor of introducing a new gearbox named as multitronic which was actually continuously variable gearbox and was developed by LuK. It replaced the old-fashioned automatic gearbox on front wheel drive vehicles, and was praised by the automotive press. It eventually proved itself to be the world's best gearbox due to the promptness in response and being light weight.
Although, this high strength chain-driven gearbox was made from highly durable metals and utilized a purpose-designed, optimized grade, fully synthetic lubricant, yet there have been a lot of complaints all around the world that it had mechanical problems and the gearbox tend to electronic glitches. Audi borrowed a lot of styling from the Asian and European manufacturers and redesigned the boot, the top edge's extensions were removed and smooth front line came in, the rear lamp assemblies were formed as a part of top line, giving it a more aerodynamic look. Over all these year, the Audi A4 B6 engines evolved so much, became more practical and fuel efficient. The range consists of the following petrol units: There is a 101bhp 4-cylinder 1.6-litre.
There are two engines of 2.0-liter; a 134hp and a 148hp 4-cylinder 20-valve FSI. There are two 1.8-liter engines; a 148hp and a 161hp 4-cylinder 20-valve. There are two S-line variations in 1.8T engine; a 178hp and 187hp 4-cylinder turbo 20-valve. There are two variations available in V6 30-valve engines; a 168hp and a 217hp 6-cylinder 2.4-liter 30-valve. The Audi A4 B6 diesel engines consist of following units; in 1.9 TDI there are three variations available. There's a 99bhp, a 113bhp, and a 128bhp 4-cylinder 1.9-liter TDI. Then there are three variations in 2.5 V6 TDI engines; it's a 153bhp, then a 161bhp, and the last one is a 178bhp 6-cylinder 2.5-liter V6 TDI 24-valve.
