Here's an example fault on the PEUGEOT 406 (1996 - 2004)

What to look for:

Check the paperwork to see if the cam belt has been changed on schedule. On most engines the cam belt must be changed within 6 years or 72,000 miles (up to R Registration) and 80,000 thereafter.

What it means:

If the cam belt and associated parts (such as water pump and tensioner) 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 will cost £170-£270.
