Why is my Audi 80's engine making unusual noises?

I have a 1995 Audi 80 and recently noticed some strange noises coming from the engine. It seems to happen more when the car is idling and goes away when I accelerate. What could be causing this issue and should I be concerned?

Hi Emma, it's important to address unusual engine noises as soon as possible. It could be a sign of a bigger problem. Some possible causes could be a worn out belt, faulty bearings, or engine misfiring. I would recommend taking your Audi 80 to a trusted mechanic for proper diagnosis and repairs.
