Audi has been producing the A4 since 1994 with 4-door sedans and the 2-door Cabriolet among its ranks. The Audi A4 B6, produced from 2000 to 2006, is the second generation of Audi's popular compact executive car. The Audi A4 B6 was well-received for its combination of style, performance and modern amenities, contributing to Audi's reputation in the luxury sedan market. Some common problems that B6 owners have encountered with their vehicles are:
Oil Consumption: Some engines in the A4 B6, especially the 1.8T turbocharged engine, were known for higher oil consumption.
Window Regulator Problems: Some owners of the Audi B6 have reported issues with failure in the power window regulators. Although this is perhaps not as serious an issue as other parts failures, it is frustrating. However, it can be fixed easily with a replacement regulator.
Rear Coolant Flange Leaks: An issue for some A4 B6 car drivers has been leakage in the rear coolant flange. This plastic flange has the tendency to warp after exposure to the heat. Afterwards it can allow coolant to seep out. The flange is out of sight and will require an experienced Audi mechanic to inspect.
Faulty Water Pump and Timing Belt: Owners have reported issues with the water pump and timing belt failing, possibly leading to a damaged engine. If you notice ticking sounds, overheating or rough idling, get to a specialized Audi repair shop for diagnostics.
If you are the owner of an Audi A4 B6 or other model, be it convertible or wagon, and you are experiencing any of the issues outlined above, you should take your vehicle to a trained German import mechanic for inspection and repair.
