Why is my Audi 80 engine making strange noises?

I've noticed some strange noises coming from my Audi 80 engine while driving. What could be causing this and what steps should I take?

There could be several reasons for the strange noises. First, check your oil level and make sure it's not low. Low oil can cause your engine to make unusual sounds.

Another possible cause is a damaged or worn out timing belt. This can cause your engine to make rattling or clicking noises. Have a mechanic inspect the belt and replace it if necessary.

If you use low-quality fuel, it can cause knocking sounds in your engine. Try using a higher octane fuel and see if the noises go away.
