How do I troubleshoot a knocking noise in my Audi 80?

I've been hearing a knocking noise coming from my Audi 80 whenever I start the engine or accelerate. What could be causing this and how do I go about fixing it?

Based on your description, it sounds like the knocking noise could be caused by worn out engine bearings or a faulty timing chain. It's important to address this issue as soon as possible to prevent further damage to your engine.

I had a similar issue with my Audi 80 and it turned out to be a loose exhaust bracket. Check your exhaust system for any loose or damaged components.
