The service schedule should be in your VW wallet
In the longlife service schedule booklet it says that the cambelt should be checked at 60k miles for 4 cylinder engines without a prescribed change interval. It then goes on to say that at 120k miles the camshaft drive belt should be replaced for 2.0ltr 110kw & 147kw TFSI models only. I started off on the longlife service regime, but changed it to a T&D regime, so don't have anything on a given length of time for the belt to be changed. Don't know what it would be for a diesel either!
Interesting thought though, I'm having my engine replaced for one that is 20 months newer, so would I adjust the service regime to suit?
