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.

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

Tl* the contact owns a 2004 audi a6. The contact stated when the vehicle is parked the throttle fluctuates. The contact took the vehicle to the dealer and the dealer change the mass air flow meter. That did not remedy the throttle fluctuation so the dealer removed the mass air flow meter. The dealer then reset the computer for the throttle body and that did not remedy the issue as well. The dealer does not know what is causing the throttle to fluctuate. The contact stated the throttle fluctuation is causing the vehicle to lunge forward when the vehicle is idle. The failure mileage was 94,500.

I have 2008 audi a6 CVT (8000 miles) with 2 major issues. One of them being carbon deposit build-up on intake valve causing engine malfunction light to come up. The problem with this is caused by direct fuel injection of their engine and is common with every fsi engine as I was told. No fix for this and they will be charging about 1500 to clean and fix the problem temporary when the warranty expires. Second issue is with multitronic CVT. This is also their design flaw where the transmission have difficulties engaging causing severe shudder and jerking during an acceleration from stop. I have difficulty controlling the throttle and if I step on the gas pedal harder, it will cause sudden acceleration and if I don't, the car will jerk back and forth and will not get decent acceleration, which is a major safety issue. Audi states that there are no complaints for this and the vehicle is running fine. I had the loaner (a4 CVT) one and the car also had the same issue, but significantly less severe. Toyota is being honest about their faults but it seems like audi is trying to hide this issue until there is a death or an injury involve, which by that time, too late.

I was parked at a stop light facing down a slight hill. The car suddenly accelerated and crashed into the car in front of me. Afterwards, upon inspection, it is possible while at idle to depress the brake pedal with a little bit of pressure to the floor. My foot must have hit the accelerator while the brake was slowly being depressed. The harder I tried to brake the faster the car went. I visited the audi dealer and we tried this experiment in a similar model with the same result. The dealer says this is part of the design! It is not possible to do this in my other car or other models I have checked. I believe it is an extremely dangerous design and could have resulted in a very serious accident if there was no car just a few feet in front of me.

1997 audi a6 unintended acceleration - stuck throttle. Only way to stop car from moving was to turn off ignition. Audi dealer (suds - normal, illinois) found ice in throttle housing and was familiar with problem on other like-model audis. If I did not have presence of mind to turn off engine I would have run into cross traffic on busy six lane highway.

I have a 2007 audi a6 quatro. I was in a parking garage and needed to turn around. Vehicle was involved in an accident, backed into a cement pole,slowly, but enough to be felt. When I put the car in forward and began to move forward, the car accelerated on it's own at a very high rate of speed. We crashed head-on into a cement wall. I know many cases of unintended acceleration have been reported, with the conclusion that drivers hit the accelerator when they thought they were hitting the brake. I was not trying to brake, I had applied the brakes when I hit the pole in reverse and was attempting to accelerate forward when the car just took off like a rocket. I did not have time to brake before we hit the wall. I hope you will investigate this. Someone easily could have been killed. Note, when filling out the vehicle information, it was an a6. *nm
