I own a 1998 audi a6 quattro (2.8 liter engine). Last winter during a cold spell some part in the pcv valve froze suddenly while driving. This caused the throttle to be stuck at about 4,000 RPM and the car turned into a rocket. Fortunately, I could bring the car to a stop and nobody was hurt. It was quite an experience though, especially since the roads were snowy and icy that day. When I brought the car to the audi dealer I was told that "it may take a week because we are swamped with many other audi a6, all with the same problem. I was told that this is some sort of design flaw with this particular model/engine, and that this will happen again in very cold weather. In april I found a short article in "der spiegel" (the german equivalent to newsweek or time magazines), reporting that the federal safety agency took 16 audi a6 in to test for exactly this problem. What is your advice to customers? Can you force audi to do something about it, since this appears to be a major safety issue? Kindest regards and thank you in advance, hagen blaszyk, md

I own a 1998 audi a6 which on several occasions has experienced sudden unintended acceleration. While attempting to slow the vehicle by braking for a stop, the engine starts to accelerate and rev all the way to 6000 rpms. The only way to avoid an accident was the depress the brake pedal as hard as possible, put the gear selector in neutral, and turn the engine off. After restarting the engine, the vehicle would operate in a normal fashion.*ak this problem extremely dangerous situation has occurred 3 times since I purchased the vehicle (audi certified pre-owned) and has been reported to the local audi dealer on several occasions. They can find nothing wrong with the car.

Car was purchased used (1998 - 90k miles-one owner-very well maintained) first week of december 2003. Incident happened approx. First week of january 2004. Audi has been contacted with no reply received to date. Incident occurred while traveling on highway approx. 50 MPH, weather conditions were clear and very cold (approx. 25f). As auto was cresting incline, it began to gather speed. Accelerator was backed off but car continued to accelerate at an alarming pace. Brakes were applied several times and as I was preparing to cut ignition car stopped accelerating. This happened is a matter of seconds, but was definitely a panic situation. Car has not repeated this condition. I was referred to your site by audiworld forum members, where I turned for any helpful information and read of similar occurrences.
