@Lou12: This is what the maintenance procedures manual says about the VW 2.0 TDI timing belt: Generally, it is not necessary to replace the belt before reaching the next replacement interval. In particular, cracks on the back side of the belt do not affect service life and cannot be claimed as goodwill or warranty measures. An Audi A6 will cost about $9,252 for maintenance and repairs during its first 10 years of service. This beats the industry average for luxury sedan models by $2,709. There is also a 26.81% chance that an A6 will require a major repair during that time. This is 12.75% better than similar vehicles in this segment. Some later VAG vehicles (up to circa 2009) introduced an 80,000 miles or 4/5 year replacement. Furthermore, later VAG vehicles are recorded in the service books as requiring a belt change at 115,000 miles! We only use Original Equipment Manufacturer belt kits which include the tensioners, any relay idlers, tensioning damper and the belt itself. Location: Highlands, Scotland.
