Long chainey?

You wrote of the Audi A6 2005 on: "All engines apart from base TDI PD 140 four cylinder are chain cam." I asked at the dealer in order to check servicing cost and was told that the 2007 MY 3.0TDi is a belt and requires changing at 75k miles or 5 years.

It's chain cam. Have a look for yourself. The old 2.5 V6 TDI was belt. But the 3.0V6 is chain. The pump is belt driven, but if the belt comes off the engine will just stop. It won’t self-destruct as it would if a valve timing belt came off, but still wise to change it at 75k or 5 years.
