Ok purchased the car October 2019, immediately noticed a burning smell, in the car. Took out to Audi multiple times ask if there was a leak, before the warranty ran out. They said no, now a year later my check engine light has come on. One diagnostic done at jiffy lube read a code that says it is the computer auxiliary output. Took the car to Audi to do a second diagnostic, they said its the thermostat, and coolant pump. My car is not ever heating and the heat and air work fine. How is it now that the car is not under warranty they notice the leak in the coolant pump, when I complained about the smell of burning water when I first purchased the car. There are no indications of a leak on my driveway. The dealership has quoted me 1683. 00 though there is a recall on the same parts. A year ago when I purchased the car there were faulty issues with the computer. Audi did replace this under warranty, but a month ago the computer would not come on several different times. Called the dealership told them it was on and off they said to bring in if it continues. Soon after the check engine light comes on, and now all of a sudden its a leak in the coolant pump allegedly. I repeatedly asked them if the CA had a leak when I first bought it only because the engine was giving off the burnt smell. They waited until the car was out of warranty to agree with me. There is a recall to fix the coolant pumps on the Audi but they are wanting to charge me to repair mine. Right now the vehicle shut off on me tonight and the epc light is on. Car will not start, nor would the engine receive the gas when trying to accelerate. Only been driving the vehicle for a year, I should not have major issues with it as of now.

This car has been great to me. Aside from a fuel pump going, just recently I was driving on the freeway and the car died. The epc light on the dash popped up and luckily I was able to coast to the side of the road. I attempted to start the car several times before calling aaa (15-20 min) while on the phone with aaa I attempted to start the car again and it fired right up. Thinking it was just a one time issue I got back on the freeway where 10 mile or so later same the same thing happened. Another 20 min of waiting before it cranked again at this point I was in a b ad area with my family and everyone was getting nervous. After it started the epc light stayed on this time and I experienced loss of power and the car coughed and stumbled terribly when I needed it most. I managed to make it home and let the car sit for a day. Hoped in and it cranked right up. No problems 15 miles later it happened again. After talking with other valued Audi owners and looking over the Audi owner forums. I have found this to be a quite common problem with the Audi across the range of there a series from 1997-2011. Please help!.

During driving epc light illuminates, rpms soar and car will not accelerate. Severe safety issue. This has occurred more than 4 times in 13 months--car was purchased brand new 13 months ago. Vehicle had to be towed to dealership for repairs three times. Two separate dealerships have "repaired" the car and returned it to me--the problem continues to occur. The most recent failures occurred within 2 weeks of each other. The car has in no way ever been repaired. Computer was re-set, and updated. Physical parts replaced as per dealer invoice throttle valve, gasket. Vehicle is defective and unsafe to drive and is currently at the dealership for repair.

On the night in question, the vehicle spontaneously went into 'full throttle mode'. The car raced ahead and was brought to a stop only with extremely heavy application of the brake pedal. While stopped and the automatic transmission in drive, the engine pulled strongly at nearly 3000 rpm. I shifted the car into park and the engine instantly raced to redline (7500 rpm). I depressed the 'engine stop' button and the car would not shut off. This, needless to say, scattered any nearby pedestrians---thankfully. I moved the shifter to 'neutral' and the engine still raced at redline. I was only able to end this by frisking myself for the physical key and inserting it into the ignition and finally shutting the car off. My next step was to call Audi's roadside assistance and have the car towed to the dealership. It is nearly brand new and describe to them the incident that occurred that Friday night. They kept the car for nearly a week and informed that they were unable to determine the cause of the malfunction and having tested it, the car was operating properly, and that I was welcome to come and take possession of it again. I can only conclude that they either have no respect for the safety of the people that drive their cars after purchase . . . . . Or they think that I made it up. Neither of these is an acceptable position. My only request was that they return to me the car only after absolutely ascertaining the cause of the full-throttle condition and repairing it. They were unable to do so and now feel perfectly comfortable putting my family back in it. This vehicle should not be on the road without a 100% conclusive diagnosis and repair ---- if ever.

When stopped at a traffic light, the vehicle surged forward. The consumer was able to control the vehicle and pulled off the road. The consumer will contact the dealer about this issue. Please provide any further details.

On a below zero day the throttle on my 1999 Audi A6 quattro was fully engaged after lifting off the pedal. Car was stopped only killing the engine via the ignition. Vehicle was restarted and problem continued. After jostling the pedal and restarting vehicle was fine.

When the temperature drops below zero, the car accelerates even after you take your foot off the gas pedal. It happened several times last winter and again during this last cold spell in January. We were lucky to be able to get the car off the road and stopped. Downshifting and heavy braking almost didn't get it stopped. The car went to the shop again for a bandaid fix but I was told by the dealership that sometimes this particular car just does that. I was charged $130. 00 for them to clean the throttle body and told that I should remove the air filter and clean the housing myself occasionally. This is absolutely unacceptable.

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.

While driving at any speed vehicle accelerated on its own. Vehicle was taken to the dealer for inspection, but dealer was unable to resolve the problem. The dealer suggested the following issues: the floor mat was on the gas pedal, wires were damaged, and a part that was previously replaced per recall failed.

Delayed throttle response.
