I have a 2008 A4, the service light goes on every 1000 mile... Is that normal? Because I'm so sick of taking the car back to the dealer every other month.

 

There is a whole thread on this topic... if it's the same thing. When you take it to the dealer, are they telling you there's a carbon build-up or your fuel injectors/intake valve? See the thread at https://www.audiforums.com/forum/sho...d.php?t=113568
Long and very important issue!
