The garage doesn't know if my van needs a new cam belt - what should I do?

My Volkswagen Caravelle T5 needs a 100,000 mile service. There's some confusion about the frequency of a cam belt change and the dealers are all saying different things. They can't tell from the national database whether one has even been fitted (but it should have been, when it was four years old). Any ideas?

If in doubt, change timing belt, tensioner, waterpump and alternator belt. Better to spend £500 - £600 on that than £5000 - £6000 on a new engine if the belt snaps.
