Here's an example fault on the VOLKSWAGEN Passat (1996 - 2004)
What to look for:
Check the paperwork to see if the cam belt has been changed on schedule. On pre 1999 engines, cam belts must be changed every 80,000 miles. On most post 2000 engines the cam belt must be changed within 110,000 miles. However, many garages recommend that bearings and pulleys can fail at 80,000 so we recommend changing all these parts at 75,000 miles.
What it means:
If the cam belt and associated parts (such as tensioner, pulleys, auxiliary belt, water pump, pump belt and fan belt) have not been changed, and the mileage is over these boundaries, the cam belt is likely to fail soon and will cause expensive damage to the engine. Usually the engine has to be replaced or at least re-built.
What to do
Ensure that the cam belt is changed before the car is driven anywhere if it is coming close to its interval. Changing the belt and other parts will cost £220 - £500.
