It depends on the engine code, not just the model. Many VW Group belts have a mileage limit and a five year age limit, whichever comes first, and some engines have had their intervals revised since the handbook was printed. Give us your registration and we will check the current factory schedule for your exact engine and tell you when it is due.
On VW Group engines, which are interference designs, the pistons hit the open valves within a revolution or two. At best that means a cylinder head rebuild with new valves; at worst, damaged pistons and a replacement engine. The car stops immediately and will not restart. This is why we treat the age limit as seriously as the mileage limit, because belts degrade sitting still.
On most TDI engines the cambelt drives the water pump, so the pump is already exposed once the belt is off and the extra labour to change it is minimal. Pumps rarely outlast two belts, and a seized or leaking pump can destroy a new belt. Paying the full belt labour a second time for a pump alone makes no sense.
Broadly, VW Group diesels and the EA211 petrols from 1.0 to 1.5 TSI are belt-driven, while the earlier EA111 and EA888 petrols use chains. There are exceptions, so we always confirm from the engine code rather than the badge. If yours turns out to be chain-driven, our timing chain page covers those repairs.
No. Rubber degrades with age regardless of mileage, which is why the schedule includes a time limit. A ten year old belt with 20,000 miles on it is a bigger risk than a five year old belt at 60,000. If the car's history cannot prove a belt change within the time limit, we recommend doing it and starting the clock again.
No. Block exemption legislation lets you service your car outside the dealer network without losing the manufacturer warranty, as long as the schedule is followed and approved parts are used. We fit genuine or OEM kits, follow the factory procedure with the correct locking tools and record the work in the service history.
Often you get no warning at all, which is the whole point of changing it on schedule. Warning signs that do appear include a tapping or slapping noise from the belt end of the engine, visible cracking or fraying on the belt edge, oil or coolant contamination on the belt, and cam correlation fault codes. Any of these means stop driving and call us.
