Audi recommends changing the belt at 80,000 miles. My car has 60,000 miles and is 4 years old - is there any history of premature cam belt failure on this model? Should I change the belt now?

I have often read in different publications that timing belts should be changed every 40000 miles regardless of what the service manual states.

I have a 1990 100 2.0E, 135,000. The engine is virtually the same as my old Passat GL5 estate which had a new cambelt at 130,000 when the waterpump bearing failed - went on to 192,000 when sold.
So don't worry.
We also have a Passat 2.0GL, I have just averted a cambelt failure by noticing a slight whine from the tension pulley - this was easily changed without disturbing the cambelt which is still perfectly OK at 180,000 (I do all my own servicing]. The pulley hardly turned - I suspect so-called belt failure is often due to these pulleys virtually seizing and friction-roasting the belt.

I agree with HJ. Timing belts are so cheap compared with the cost of a wrecked engine that I can't see any sense in trying to sqeeze more mileage out of them. It's 40,000 miles for me every time.
