How to fix a rattling noise in my Audi 80?

I have been hearing a rattling or knocking noise coming from my Audi 80's engine. Can anyone tell me what could be causing this and how can I fix it?

It could be a loose heat shield or exhaust component causing the rattling noise. I suggest taking it to a mechanic for a proper diagnosis and repair if needed.

Check your engine mount and transmission mount for any wear or damage. They may need to be replaced if they are causing the rattling noise.

Make sure to also check your spark plugs and ignition coils. Worn out or damaged spark plugs can cause a rattling noise in the engine.
