I think I read somewhere, unless I'm mistaken, that the timing belt has some sort of astronomical lifespan - 190k miles or so before needing to be changed. I've not got around to reading the car service manual yet so I don't know if this is true.
Yes, it's true, thanks to the new "oval" camshaft gear, which gives pressure on the belt only when valves need to be opened. So it won't need to be replaced so often. It also minimise the strong vibrations which are typical for 3-cylinder engines.
I've checked the VW service book that was with my up! and it states that the cambelt is checked at 160000m and then every 20000m thereafter. Unless I have missed something no mention at all of a schedule for changing the belt or of a need tocheck the belt before this point.
Soa servicing cost saving for long term up! owners. This also has to help with residuals for ups with higher mileages.
