In the 4.2L of the D2 A8/S8, a belt drives the exhaust camshafts from the crankshaft, but the intake cams are chain driven off of the exhaust cams. Only the belt gets replaced.

Boy, that's a lot of gobbledygook letters and numbers, to most. Heh.

C6 A6, D3, and B6S4.

Surprised the heck out of me, when I learned that. Couldn't believe Audi had put both the belt and the chain engine in the C5 platform.
