Six problems related to other fuel system have been reported for the 1999 Audi A6. The most recently reported issues are listed below.
Have had nothing but problems with the Audi A6 since inception. Car started making a horrible noise that sounds like it is coming from engine or transmission. Car cannot pass emissions. Engine smoking fluid is pouring out of front of transmission. The car dealer: nalley Audi in roswell, georgia. The car dealer nalley Audi fraudulently took money from me and never repaired vehicle.
Car accelerate on it's own. About 15 minutes into trip, started to feel the car accelerating on it's own. When I let go of the accelerator, rpm did not drop. Double check the cruise control, turn it on and off makes no difference. Pull off road, put in neutral to stop, race to 4k rpm. Restart car, still @4k. Stopped for 5 minutes, restart, back to normal. An accident waiting to happen!.
On January 19, returning home from a family trip, the throttle on our 1999 A6 stuck open at 65mph. I was trapped in the left lane of a 4 lane highway with no shoulder to pull onto due to heavy snow accumulation. I had stand on the brakes as hard as I could to avoid smashing into the vehicles ahead of me that started to slow down for an upcoming speed zone. I overheated my brakes almost to the point of failure in order to pull into the right lane and make a quick exit where I turned off the key. My brakes smoked and smelled for about 15 minutes in zero temperatures. After letting it sit for a while I tried to start it again and it immediately redlined. We were eventually able to restart and drive the car home at a very slow and cautious pace using back roads. This was a terrifying and very dangerous, life threatening situation for my self and my family. Four days after the "repair" at john holtz Audi the throttle again froze when my wife had to slow for a stopping school bus. The exact same symptoms occured. I am a member of the Audi quatro club. Through my exposure to many other Audi owners I have learned that this problem is fairly common in very cold weather and the Audi solution of cleaning the throttle body does not prevent the problem from recurring. The authorized Audi mechanic who worked on my car in rochester used to work in vermont. He told me that the problem was often seen there, but infrequent in rochester, NY. He was relcuctant to discuss the situation extensively, saying" I have too many years in. " a friend of mine is an aftermarket Audi specialist who has documented this problem repeatedly.

This, and apparently most, Audi A6 vehicles do not have functioning gas guages. As a result the driver does not know when the vehicle will run out of gas. I have run this vehicle out of gas 5 time since the problem began, the last at 65 mph in the fast lane of CA 101 freeway. The sudden vehicle slowdown almost caused a multi-car, high speed accident. Audi has repeatedly attempted to fix the problem but after 8 months, report that they do not have a fix available.
A malfunctioned gas gauge. Consumer was unable to get it repaired or replaced. Dealer/mfr notified. . Et.
The gas guage reads that there is more fuel in the vehicle than there actually is. Dealer replaced gas sensor, and problem still exists.
