What could be causing strange noises under the hood of my Audi 80?

I have been hearing strange rattling and grinding noises coming from under the hood of my Audi 80. It happens primarily when I am driving at low speeds and seems to be coming from the front of the car. Any suggestions on what could be causing this and how to fix it?

One possible cause could be a worn-out serpentine belt. If the belt starts to fray or wear down, it can produce strange noises. I suggest having it checked and replaced if necessary.

Another potential issue could be a loose exhaust pipe or muffler. This can cause rattling noises when the car is in motion. You may want to get under the car and check if any of these parts are loose or damaged.
