when is the time to change timing belt on 2004 Audi A8 Quattro

To change the timingbelt and water pump and also change rear brake?

Asked by for the 2004 Audi A8 Quattro
Go to the repair/maintenance section at the repairpal homepage and put in your car and see what it says about the belt. If water pump is timing belt driven then replace at same time. The brakes should be checked and replace as needed.
