What is causing the engine of my Audi 80 to make strange noises?

I recently noticed that my Audi 80's engine has been making strange noises, especially when I accelerate. The car still runs smoothly, but the noise is becoming more noticeable. What could be causing this issue?

It is possible that there may be an issue with your car's exhaust system. I recommend taking it to a trusted mechanic for a diagnostic test to pinpoint the exact issue.

Have you checked your oil levels recently? Low oil levels can cause strange engine noises. Make sure to check and top up your oil if needed.
