Audi A8 – Head Gasket Service

Timing belt replacement on the Audi A8 requires a fair amount of disassembly on the front end of the vehicle. The Audi 4, 6 and 8 cylinder engines are high compression types, failure of the timing belt will result in major engine damage. Although scheduled by Audi for 90,000 miles, we have found loose or severely worn timing belts and tensioners at the 75K mile mark. When replacing the rubber timing belt, all belt rollers, water pump and thermostat must be replaced. This is a service you only want to do every 100,000 miles. We have noted a number of the Audi V8s with head gasket leaks or seepage, this is a straightforward matter to correct when the car is disassembled for the timing chain.
