What is your mileage? Do you have the car manual hidden on the compartment underneath the steering wheel? If you find it, then it contains details about your maintenance schedule.

I have an 03 B6 A4 Avant and the manual said the timing belt must be replaced at 105K miles. However, I have read in these forums and elsewhere that replacing the timing belt at 80-85K is smarter, so that you can avoid the heartache when a 'premature' timing belt failure actually do happen.

 

If you dont know when it was done as you are a new owner, have it done. If you just haven't had it done and it's at 100k DO IT NOW! I had one break on mine and Just parts and machine work was $2200. A $7-800 service is cheap.

 

I had the timing belt, water pump, cam seals and plugs replaced ( because of check engine light ), for $1350. I hope it keeps on chugging
