A4 TDI 100 service schedule

[wickerman]

I had an Audi A6 2.4 petrol servicing schedule was every 10k/12months what ever came first. What is the rate for a A4 DIESEL ? Another question if I may, the A4 I'm about to buy had it's timing belt & tensioner replaced at 56k at the end of 2005 the car now has 80k on the clock when will it require changing, my A6 was every 70k, i'm just concerned about it snapping, reading some of the threads it's getting me worried !
