Why is my Audi A1 making strange noises under the hood?

I recently noticed that my Audi A1 is making some weird noises when I start the engine and while driving. What could be causing this and how can I fix it?

One of the common reasons for strange noises in an Audi A1 is a worn out serpentine belt. It's important to get this checked and replaced if necessary, as a snapped belt can cause serious damage to the engine. I would recommend taking your car to a trusted mechanic for a diagnosis and repair.
