Follow your manufacturer's recommendations. If you don't have them, check with the dealer. Most cars seem to need it at about 70,000 miles. A trusted mechanic could also check it for wear.
It should be a timing belt and i believe Audi recommends every 105,000 miles, but... Replace it at 90,000 or sooner i have seen them fail well before 105,000
I have a 1995 Avalon; you should replace the timing belt at 75 thousand miles; good luck !
Depending on your specific year, make & model, it may vary. A 2000 Audi Quattro A4 with a 1.8 should replace timing belt and timing belt tensioner at 100,000 miles. It should be checked earlier if your vehicle is subject to severe treatment.
you should replace the timing belt around 60k miles. That's whats recommended by the manufacturer.
Only the 4 cylinder has a timing belt. On a 1983-97 replace it at 60,000 miles=On a 1998 up, replace at 120,000 miles.=
every 60,000 miles.
100,000 miles
80.thousands miles
It should be replaced every 90,000 miles.
Replace the timing belt every 105,000 miles.
The first timing belt change is at 60,000 miles.
If it's a belt, then maybe 60,000 miles. Timing chains last a lot longer.
