I just picked up my 3.0 A4, it has 70,000 on it, should I do the timing belt? I know it says to do it at 105,000 in the manual but I have heard to do it earlier on here. Or is that only more crucial with the 1.8 engine?

 

The 3.0L belt usually holds out longer than the 1.8T engine but i have done a couple of cylinder heads at 90k or so for snapped timing belts on the 3.0 engine so i would recommend replacing the T belt.
