I think I know the answer to this but anyway... I just had the MB back from its MoT (pass no advisories

) and a fluid service. The garage (Four Circles, in Bristol) put on a note saying "Cambelt last changed in 2010". No worries, I thought, Dialynx replaced it just a couple of years ago. Turns out that was actuallyfive years ago. In that time I've done about 6000 miles. I'm very well aware of the need not to take chances with cambelts. What is the prevailing wisdom nowadays for cambelts still five years, or forty thousand miles, which ever comes first?
