Audi is the maker of the A4 series of compact executive vehicles. Audi, which operates under the umbrella of the Volkswagen Group of automakers, has been producing the A4 since 1994 with 4-door sedans and the 2-door Cabriolet among its ranks. Some common problems that B6 owners have encountered with their vehicles are:
Sunroof Switch Problems: One source of aggravation for Audi owners is a problem with the sunroof switch. If there is an issue with the contacts in the switch that operates the motor of the sunroof, this can cause the roof to open and close without being prompted to do so by the driver.
Coil Pack Problems: Audi A4s that come equipped with the 1.8T coil pack may experience problems with failure. This problem did prompt a recall by Audi and only affected a small number of car owners.
Windshield Wiper Issues: If you are an Audi owner who has experienced problems with your windshield wipers seizing up, then you are not alone. Don't put off having your wipers fixed. To put off this problem is to risk an accident in bad weather.
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 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 a mechanic to inspect.
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.
