Why is my Audi 80 making a clicking noise?

I've noticed a consistently clicking noise coming from my Audi 80's engine. It seems to be coming from the front of the car. What could be causing this and how can I fix it?

It's possible that the clicking noise is coming from a faulty drive belt. It's important to get this checked and replaced if needed, as a broken belt can cause major damage to the engine.

Another potential cause could be a loose or worn-out pulley. This can usually be fixed by tightening or replacing the pulley.
