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.

When filling the gas tank in my 99 audi a6 quattro pressure builds inside the tank and sprays back at me. This has happened each time I put gas in it full or not. A recall was made but, not for my VIN. I spoke with a audi rep. And a dealership and they said there's nothing that can be done unless I pay for it. I would but, there is already a recall made for that car just not that VIN. It's a hazard and I've had other problems that I paid for. Please let me know if anything can be done. Thank you for your time!

I have recently experience the exact same sudden acceleration with my audi a6 quattro. The temperature outdoors was very cold and I was traveling up a hill when the car kept accelerating on its own. While applying pressure to the brakes the car continued to accelerate. Luckily I was able to pull the car off the road and shifted into park. Upon placing the car in park the tachometer red lined. After taking it to the garage the technician determined he could not find anything wrong the automobile. The following week my husband drove the car and experienced the exact same thing. Again our car is in the garage and the technicians are trying to determine a cause. To date, they have been unsuccessful in finding the problem.

Fuel leak from supply fuel line in an 1999 audi a6 during very cold weather. When temperatures drop below 15-20 f the crimped end of the fuel supply line leaks fuel, which creates an intense fuel smell in the cabin, but only if not moving at high speeds. The fuel leaking from the hose travels towards the back of the engine and eventually drips onto the exhaust manifold creating intense smoke. Apparently the cold line intensified by super cooled gas streaming through it causes the metal part of the line to contract at a sufficient rate as to allow fuel to leak out. When the fule line warms up, the leaking stops. Dealer could not replicate the problem because the ambient temperature was 40f at the time of testing and hence refused to aknowledge the problem. Subsequently the problem re-occured and I took several close-up pictures showing the leak and the ambient temperature. I can make the pictures available upon request. This is very dangerous condition that can go undetected at high speeds (high airflow dissipitates the smell) and/or if cabin air gets recirculated.

Engine malfunction. *mr the consumers wife was driving the vehicle when it suddenly began to race, she was unable to stop the vehicle. The consumer ran stop signs and an intersection until she finally turned the vehicle off. The vehicle continued to race, and due to the level of racing, the crankcase seal blew out which caused oil to flow. The dealer advised the consumer the problem was due to a stuck fuel injector. Scc

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!

Vehicle fully accelerated on it own, resulting in very high speeds in traffic and on downhill drive. Very difficult to stop vehicle when careening down steep hill toward an intersection. Reportedly can happen in cold weather at any time. Dangerous!!

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.
