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.
