I own a 2008 Audi A6 quattro which has 40k miles. Recently the check engine light came up and when I took it to the dealer they mentioned that the engine cylinder is misfiring because of carbon deposits. The dealer said that the car is not meant for NJ driving, it is meant to be driven in the autobahn. Dealership provided a fuel additive and said that things should be fine. This is not acceptable for a car that is in warranty.

My check engine light is marking misfire but I have gotten a complete tune-up, changed all 6 coils on the engine changed all the spark plugs, I've done everything possible and changed everything I can that has to do with the engine all brand new and nothing has worked and its still saying misfire. . . I've googled this problem for Audi's and there were so many people complaining about the same thing. . . Also, I am having a problem with the electrical system as well one day my windows work the next it doesn't sometimes my lights will work and sometimes it doesn't, sometimes my radio will work some times it doesn't, the information on my dash sometimes doesn't light up and I can't see anything at night time, I have constantly been to the mechanics trying to figure out what's going on but we can't find the problem, I've spent so much money on this car trying to fix the problems but its really making it hard for me to keep spending money on my car and not being able to figure out what's wrong with it. This is very dangerous because if I'm driving at night time and my lights end up not working I can cause a very big accident I am very very concerned about these defects, my safety and others safety and would really appreciate if you can please investigate this problem because its happened to so many people. I also think something is wrong with the fuel system I'll put $60 in gas and two days later it'll almost mark empty I really don't understand how that is possible but if there's an answer I would really want to know. Thank you so much and I really appreciate 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.
