What could be causing strange noises in my Audi 80's engine?

I recently noticed strange noises coming from my Audi 80's engine while driving. It's been running fine so far, but I'm worried it could be a sign of a bigger problem. Any ideas on what could be causing these noises and how I can fix it?

It's possible that the strange noises are caused by a worn out belt or a damaged pulley. I would recommend taking your Audi 80 to a mechanic to get it checked and replaced if needed.

Have you checked your oil levels and changed the oil recently? Low levels or dirty oil can also cause unusual engine noises. Make sure to keep up with regular oil changes to prevent any potential issues.
