while that is a good idea, the problem is so prevalent in the TT's and A4's its more than just regular maintenance. Audi made a faulty, cheap, plastic timing tensioner and it is known to fail. which causes major engine failure. dont believe me go to the Audi forums and see for your self . plus Audi maintenance costs a shit load..
