Engine Problems of Audi A6

The contact owns a 2002 Audi A6. The vehicle was taken to the dealership on June 4, 2010 for the manufacturers voluntary coil spring recall; however, the defected coil springs caused the catalytic converter to fail. The catalytic converter was replaced; and the coil spring repair didn't correct the failure. The vehicle lost power while attempting to accelerate. The vehicle was taken to a local mechanic who located the failure as the vehicles six engine cylinder. The manufacturer was contacted advised the contact that they would not reimburse him for the catalytic converter. The vehicle wasn't repaired. The failure mileage was 90,476 and the current mileage was 93,400.

Unintended acceleration -- car accelerated rapidly. Would not slow even when driver's foot was not on the gas. Engine revved rapidly and would not return to normal idle speed.

I drive a 1997, A6 Audi quattro station wagon. Over the past 2 winters, I have had 2 very similar incidents. On extremely cold mornings while driving into work the car accelerated on its own. Each time I had to pull off the road, throw the car into neutral and shut to car off.

I have a 2001 Audi A6 2. 7t and it has almost caused me to get into severe accidents where I would have been seriously injured or killed in a side impact collision. The culprit is this: if you depress the brake (as if you were stopping or coming to a complete stop) and try to reaccelerate, there is little to no acceleration. This "hesitation" has almost got me killed several times. There are hundreds of other Audi A6 consumers regardless of model engine (2. 8, 2. 7t, 3. 0 and 4. 2) that have experienced this problem. Thus, it is unacceptable for Audi USA to say this is "normal" and "inherent in the operation of turbochargers" as this is what they have told me before while the car was being serviced. Although I do understand that turbochargers create what is deemed as "turbo lag" on acceleration, I experience major delays in any acceleration immediately after I have depressed the brake (at any speed) and then try to reaccelerate. This is a serious issue and needs to be fixed or remedied immediately. Please see the posting at Audiworld (the largest online forum for Audi owners). . Read more...

I had a leak in the cam seal and it seems that a lot of others have experienced it in the Audi forum.

Engine check light is on. Dealer has inspected vehicle five times and could not duplicate or correct the problem.

My car has been in the shop for repairs every 3000 miles. Some for major problems such as replacing the steering assembly and other times for multiple repairs of the same problems (engine malfunction light on).

Cam seals and main seal both failed and cost over $2000 to repair out of warranty. Very upset since the car only had 58000 miles on it.

Vehicle will slow down without and shut down without prior warning. Dealership is aware of problem.
