How to change the timing belt on my Audi 80?

I have recently purchased an Audi 80 and have been advised to change the timing belt. Can someone walk me through the steps and any necessary precautions?

The first step is to locate the timing belt in your Audi 80. It is usually located behind the plastic panels on the side of the engine. Make sure the engine is cool before starting. You will need a wrench, a socket set, and possibly a tensioner tool to remove and replace the belt.
