Why is my Audi 80 making a strange noise while idling?

My Audi 80 has started making a strange noise while idling. It almost sounds like a rattling or buzzing noise. What could be causing this and how can I fix it?

It's important to get this noise checked out by a mechanic as soon as possible, as it could be a sign of a larger issue. However, in some cases, it could simply be a loose or damaged component in the engine bay. Have a mechanic do a thorough inspection and make any necessary repairs.

One common cause of strange noises in an Audi 80 is a loose or worn fan belt. This can create a rattling or buzzing noise. Have a mechanic check the tension and condition of your fan belt and replace it if necessary.
