The service schedule mentions the timing belt separately, not in the "interval" maintenances, and doesn't indicate a time period. However, even if you were to go by the intervals, Audi says you need to do the next interval if the mileage is not reached, one year after the previous. A8 3.0L V6 TDI, A8 3.0L V6 TFSI, *A8 4.0L, V8 TFSI, TTS and TT RS only * Note: The S8 4.0L V8 engine is not included in this interval.

If you wanted to do this as a preventative maintenance, 125,000-150,000 miles would be a reasonable spot. Pretty much you shouldn't worry unless you hear the chains making noise or get a timing code. Quick Navigation C7 A6/S6/RS6 A7/S7/RS7 Return Top. The 4.2 liter 40 valve V8 engine was used in several Audi A6, S6, RS6, A8, and S8 models. The 40V V8 engine is driven by a timing belt system which links the cylinder heads, camshafts, and crankshaft to run in sync. This Audi A8 timing belt system consists of a wear resistant, high strength, corded/molded rubber timing belt (a.k.a. toothed belt). Audi UK recommends a cambelt change interval of five years or 140,000 miles, whichever comes first, for the above vehicle. This is to ensure optimum safety and performance. The cambelt is one of the hardest-working parts in the engine. 1ceBiI8.
