1999 Audi A8 Q&A
1999 Audi A8 Question: Should I have the timing belt replaced?
The timing belt is due by age. If it is the original timing belt, it is over 72 months old which is the time interval for the belt, before they crack. A timing belt has a rubber that cracks, much like tires. After about 72 months ( 6 years ) the rubber will crack or get 'age cracks'. - dandd
