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.
Got a warning light that adaptive cruise and braking were not available. According to the service dept. There was a seam in the body that was not welded properly in the manufacturing process. I have 6500 miles on my car. They said that water was leaking in on electrical modules. This problem happens while driving.
Vehicle stumbles and cuts off at a few moments of idling. It has also lost power and the gained it back moments later at rapid pace.
While driving 60 mph on the freeway, the car accelerated on its own to 72 mph as if going into cruise control. Confirmed the cruise control switch was turned off. Applied the brakes seven times. Car did not respond to braking. Engine seemed to race against the brakes. I put the car in neutral, moved to side of the road. Applied the hand brake. Turned key off. Car slowed then stopped. Since this incident the car was test driven twice by mechanics, during which it seemed to operate normally. On january 27, 2015 the car was taken to the local dealer, bellevue audi, for diagnosis. Awaiting results. *Tr
The first throttle valve malfunction happened on july 2013. Cost to repair 1557.95 Part cost 878.00 Mileage 66784 the second malfunction happened on oct. 14, 2014 To repair 1200.00 Part cost 913.00, Mileage 69202 what happens here is the engine shuts down. There could have been e major accident if she was rear ended. I called audi to tell them the part was defective, but they would not listen. That is why I think there should be a recall, to send them a message. *Tr
On the morning of february 11th 2014, my daughter was on her way to school when her vehicle began to accelerate on its own. She believes she was going between 25 and 35 miles per hour when the vehicle began to accelerate and topped out at 70 before she was able to get it to slow down. She stated to me after the incident that she had to press both feet on the brake pedal to get the car to stop. Fortunately there was no accident and she was able to safely pull over to the side of the road. I took her car to...

friend's house, dropped her off at school and took her vehicle to sunny side audi in middleburg ohio. They found the speed control was malfunctioning. They told me that it would be between $800 and $1000 to repair. I paid them $138.00 To disconnect the cruise control and we haven't had any continuing problems with the cruise control. The $138 isn't going to break me but then again breaking me is why I am writing this complaint. I have given this incident a lot of thought; what could have happened, how lucky we are that my daughter didn't panic and then I realized that there are more than likely many more 1996 audi a6's out there and who knows other audi's in general with the same cruise control set up that is installed in our car that have or will malfunction. I am hoping that someone will look into this incident. You are more than welcome to inspect our vehicle. I was surprised by the response of the sunny side audi service department. They offered us no support or avenue for assistance for repair and treated this incident like any other vehicle repair. We were lucky it wasn't worse and we are grateful but I would like to be reimbursed and have the vehicle properly repaired. *Tr
Tl* the contact owns a 2001 audi a6. The contact stated that while driving 30 mph, the accelerator pedal abnormally traveled to the floorboard. The contact applied the brakes but the vehicle continued to accelerate. The vehicle was towed to a mechanic for inspection where they stated that the pedal module was stuck and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 89,000.
I was driving at about 65 mph. I went to pass another car in a passing zone so I accelerated full throttle. The gas pedal stuck and the car continued to accelerate. I braked and maneuvered the car to the side of the road and turned it off. After a while it released. I started the car again and continued home, not pushing the pedal down any farther than necessary. I will take it in to be fixed. There was nothing obscuring the pedal and the floor mat was clicked into place. I found no evidence of a recall, but many audi owners have reported similar experiences, so I am not sure why this isn't a recall issue. *Tr
Car brake lights are on all the time and it reves all the time. *Tr
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! *Tr

1999 Audi a6 quattro suddenly accelerated. I was pulling into a parking slot at maybe 5 mph, my foot was lightly pressing on the brake pedal, as I was nearly in the parking stall. The engine was at idle speed. As I coasted into the parking stall with my foot on the brake pedal the engine suddenly and without any prior warning revved up to above 3000 rpm. The car lurched forward hitting the parking curb directly in front of me. I immediately applied more pressure to the brake pedal to keep the car from jumping...

over the curb, and shifted the gear selector into n. The engine then revved even higher, at which point I turned off the key. With the key off, I moved the gear selector to p, and restarted the engine. The vehicle then ran idled at normal speed, and drove normally to my home about 1/4 mile away. I'm afraid to drive the vehicle. This is the second time this has happened; the first time it happened was as I was coasting to a stop at a red traffic light. Again my foot was on the brake and the engine was returning to idle speed. As I approached the intersection the engine revved causing me to coast through the intersection before being able to bring the vehicle to a full stop, again by applying strong breaking force. I then put the transmission in n and the engine revved higher, so I switched off the key. Thankfully the other vehicles had already cleared the intersection and there was no collision. When I restarted the vehicle, it idled and drove as normal again. The outside temperature was above 45 degrees fahrenheit and the pavement was dry in both cases. *Tr
Sudden acceleration, caused by driver's loose floor mat. Started car in garage. In park, engine ran at 4,000 rpm from start. Tried to kick down gas pedal several times, no change. Ignition on and off three times, no change. Pressed firmly on the brake, shifted to reverse. I knew it would lurch. Got out of garage, pressing firmly. Rpms dropped to normal 1,000 range. Shifted into drive, car rpm increased to 4,000 rpm and lurched. Sat there for five minutes thinking it would settle down. Nothing. I then decided to check the floor mat. It was on top of the gas pedal. It had moved forward because the one of the securing locks on the mat had broken free
