Why is my Audi A2's engine making loud noises?

I recently noticed that my Audi A2's engine is making loud noises. I am concerned that this could be a sign of a bigger issue. What could be causing this and what steps should I take to address it?

It's possible that your engine oil needs to be changed. I would recommend checking the oil level and schedule a oil change if necessary. Loud engine noises can also be caused by worn out belts or pulleys. It's best to have a mechanic take a look and replace any necessary parts.

Have you noticed any other symptoms in addition to the loud noises? A misfiring engine or a worn out muffler could also be the culprit. I recommend bringing your Audi A2 to a trusted mechanic for a full diagnostic.
