very simple, never.
the 2.8 and 2.9 vr6 engines do not have cambelts, they have camchains.
the chains do not have a reccomended change interval however they may start to rattle slightly after many years of abuse then they could do with changing other than that they should outlive the car.

how to oil filter on vw sharan 19 dti 53
GOOD LUCK
it has a chain not belt
With the ignition on hold down the mileage reste button until you get 4 dashes or use the socket under the ash tray to connect the vag reset tool.
why do you think you need to change the clutch, the gearboxes on the petrol engined cars will be differant to the diesels. You would only have to change the clutch if it was not working

I am not sure whether this is specific to the Volkswagen Sharan, however, I used to own a Vauxhall Calibra, which has a cambelt sensor fitted, which would basically sense when the belt was becoming loose or perishing and in need of a change and would send a signal to the Engine Management Unit to limit the engine speed to prevent the cambelt breaking and causing unncessary damage. Basically it would pull to 3,000 revs in the usual fashion, but would then pull REALLY slowly beyond this. Stopping the car and re-starting the engine would effectively cancel this, but upon hitting the magic 3,000 revs again, it would happen again. This would usually coincide with the ECU light illuminating on the dashboard indicating that something was up. It could be that VW have fitted a similar thing to the Sharan, but will depend upon the engine you have. 2.0 and 2.3 litre petrols together with 1.9tdi will have them. The 2.9 VR6 (that I own) has timing chains so removes the need to have the cambelt replaced. So all in all, if you've got one, I'd say get your Cambelt checked out. While it can prove expensive to replace, it will be more costly to replace your engine should the belt snap and cause catastrophic failure. I could, of course, be barking up the wrong tree as I don't have that much experience of the Sharan, but I may be right.
