Three problems related to engine and engine cooling have been reported for the 1999 Audi A4. The most recently reported issues are listed below.
The car is experiencing unintended acceleration, usually, but not always, after heavy acceleration. Over 10 occurrences. Cannot remedy by pulling back the accelerator. Car must be turned off and the engine must record 0 rpm to remedy the problem.
1999 Audi A4 2. 8. Third time the car needs to replace leaking cam seals on engine. All cam seal repairs completed by original dealer repair dept. First repair was only at 39,000 miles and 6 months off of warranty, in November 2003. 2nd repair was only two years and 30,000 miles later, at 69,000 miles, in February 2005. 3rd repair now needed, only after 35,000 miles later, at 105,000 miles. I have read that this is an ongoing problem with the A4 model manufactured over the course of several years, including 1999, and that the cam seals should last much longer than 35,000 miles. Audi corporate refused to assist with expenses with the 2nd repair. I am in discussions with Audi corporate about the expenses for the 3rd repair. Since this is a persistent problem with my vehicle, and as I've read, many other 1999 A4s, I encourage the NHTSA to research this cam seal engine defect, and issue a defect recall. I had submitted the same request several years ago, when the first incident occurred. Thank you. Karen blumenfeld.
After starting the vehicle a fire broke out inside the engine compartment. Dealership was notified, but did not resolve the problem.
