Audi is offering private customers free MoT tests for life at its UK dealerships when they replace their cam belt.

A cam belt replacement will cost customers £449 for engines up to 2.0-litres and £599 for higher capacity units. The price of a typical MoT test is £49.99.

Audi UK recommends changing the cam belt once the mileage specified in the Audi service schedule is reached or at every five-year interval, whichever comes first. During every Audi cam belt replacement, the engine is disassembled and the belt itself replaced along with the cam belt tensioner.

Audi has said the offer is fully transferable to subsequent owners for the life of the vehicle and all privately owned Audi models of any age are eligible.
