While there is no exact Toyota timing chain replacement schedule, Toyota timing chains may need to be replaced when the chain loosens, which may occur up to around the 250,000 mile mark. Timing belts typically require maintenance at about 60k to 100k miles, depending on the specific model and year. Because there is a night and day difference 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.

You may wonder what the difference is between a timing chain and a timing belt. Timing chains usually last longer than belts do in most cases (Damn you I am considering a 2008 A8L or a 2007 S8. I am looking for info regarding the trouble spots on the V10 engine and the S8 vs the A8. Does the V10 have a timing chain like the 2008+ A8s or does it have a timing belt like the 2007 A8. How much of a bump in general maintenance costs am I looking at going from a A8L to S8? . I have seen a handful of belt failures mentioned over the years on the C5 (A6) board, which in its day probably had 5x the message traffic this one does. Change interval on C5 RS6 was every 30K by the way. And, Audi Care used to go 75K instead of 65K, until I guess someone woke up that they were covering the belt job.

A6 / S6 (C5 Platform) Discussion - Timing Belt or Timing Chain - BACKGROUND My daughter just bought, from a local reputable Audi (new & used) Car Dealer (Western Chicago Suburbs) a used 2003 Audi A6 with 108,000 miles on the odometer for our grandson. From the pictures she sent me all I can tell is the vehicle is a A8 / S8 (D3 Platform) Discussion - OMG Timing belt broke on my 2004 A8, catastrofic damage-WTF - I'm so pissed I don't know where to start. Sure I have 110,000 miles and know I'm due for a new belt but it didn't happen in time. I searched the archives and didn't find any D3 cars with a broken belt. It started last A8 / S8 (D3 Platform) Discussion - timing chain replacement? - I just purchased an 07 A8. I was under the impression that with the chains replacement wasn't necessary. But was told by a friend that the experts still recommend replacing them every 100,000. Can anyone affirm or dispute this? Thanks
