Why is my Audi 80 producing a rattling sound while idling?

I have noticed that my Audi 80 has started producing a rattling sound while idling. This sound disappears when I accelerate. What could be causing this issue and how can I solve it?

The most common reason for a rattling sound while idling in an Audi 80 is a worn out serpentine belt. It may be due for replacement, so have it checked by a mechanic. You can also try tightening it to see if the sound goes away.

Another potential cause could be a damaged exhaust manifold or heat shield. Take your car to a professional for inspection and repair if needed. It's not a problem you can fix on your own.

Check your engine mounts to make sure they are not cracked or broken. If they are, you will need to replace them to eliminate the rattling noise. This is a relatively easy fix and can be done by any mechanic.
