What is the best way to diagnose an Audi 80 engine issue?

I have been experiencing some strange noises coming from my Audi 80 engine lately. What is the most efficient and reliable way to diagnose and fix this issue?

The best way to diagnose an Audi 80 engine issue is to use an OBD-II scanner to read the trouble codes and pinpoint the exact problem. After identifying the malfunction, consult a mechanic to confirm the issue and determine the best course of action.

One possible cause for strange engine noises in an Audi 80 could be a worn-out timing belt. Make sure to check and replace the timing belt if needed to prevent any further damage to your engine.
