What is a common issue with the Audi 80's engine?

I've been hearing some strange noises coming from the engine while driving my Audi 80. It's making a rattling sound and I'm worried there might be a problem. Can anyone offer any insight on what could be causing this issue?

It could be a sign of a worn-out belt or pulley, which could lead to bigger problems down the road. It's best to have a mechanic take a look at it as soon as possible.

It's possible that your engine is low on oil, which could cause extra friction and lead to that rattling sound. Check your oil levels and top up if necessary.
