Why does my Audi 80 engine make a strange noise when I accelerate?

I recently noticed that my Audi 80 has started making a strange noise when I accelerate. It sounds like a whining or rattling noise, and it only happens when I press down on the gas pedal. What could be causing this issue?

It is possible that your serpentine belt is worn out or needs to be replaced. This can cause a whining noise when accelerating. I would recommend having a mechanic check and replace the belt if needed.

Another possible cause could be an issue with your exhaust system. A loose or damaged exhaust pipe can create a rattling noise when accelerating. I suggest having a mechanic check and repair any issues with your exhaust.
