Why is my Audi A1 engine making abnormal noises?

I've noticed that my Audi A1's engine is making strange noises that it didn't make before. What could be causing this and what should I do about it?

It's possible that there is an issue with your engine's components, such as the belts or bearings. It's important to have this checked out by a professional mechanic as soon as possible to avoid further damage.

There could also be an issue with the fuel system, such as clogged filters or a failing fuel pump. This can lead to poor performance and potentially expensive repairs if left unaddressed.
