Xs2man is correct, Audi state 80k, but 60k is an accepted maximum. Mine 'went' at 128k as the work done in the change at 80k wasn't as I expected (pulleys were 'inspected' but not replaced) and it cost me many £000's.
Its well over at 135k, if you get it would I would drive it straight to the garage to have it done! Along with all ancillaries, water pump, thermo etc.
