How to diagnose an engine issue in my Audi?

I recently noticed strange noises coming from my Audi's engine. How can I determine the cause of the issue?

It's important to pay attention to the type of noise your engine is making. A knocking noise could indicate a problem with the bearings, while a rattling noise may suggest a loose component.

Check for any warning lights on your dashboard. This could indicate an issue with the engine's sensors.

Have a qualified mechanic or dealership perform a diagnostic test on your engine. They will be able to identify the specific issue and provide a solution.
