Why is my Audi 80 making a strange noise when accelerating?

I noticed that my Audi 80 is making a strange noise when I accelerate. It sounds like a rattling or knocking noise. What could be the cause of this and how can I fix it?

This strange noise could be a sign of a problem with your engine. It's important to have it checked by a professional mechanic.

If the noise only occurs when you accelerate, it could be a sign of a loose or worn out belt. Have it checked and replaced if necessary.
