 Like mentioned in another review, the timing tensioner caused a check engine light to turn on at approx. 74K miles and after several times of resetting the light, it refused to go away. My dealership finally took it in and called me initially to repair it for $1,800, which they said if I don't take care of will cost 8K worth of damage. They were not able to give me a cause for it and I told them to give me the quote and details and I will take it and fix it for cheaper elsewhere. Then they said they will contact Audi and call me back if anything can be done. After a few hours they called and said Audi would cover the entire cost and they repaired it within 24 hrs for no cost. I am happy they did that, but I am sure this has affected the value of my car and my fear of something else going wrong with it. I bought this car brand new thinking I will not have to deal will damages from low quality build and not including the regular maintenance I take it for, I have had to go to the dealership many more times for fixing recalls and other minor sensor issues. Right now my navigation and media system stopped working after they fixed the engine issue and I am not sure how to connect the two incidents. The dealerships have been pretty good , but I am highly disappointed with the low quality of the car itself.
