What could be causing a rattling noise in my Audi 80?

I've noticed a rattling noise coming from my Audi 80, especially when I accelerate. It's been going on for a few weeks now. Could this be a sign of a larger issue, or is it something I can fix on my own?

This could be caused by a loose heat shield on your exhaust system. It's always best to have it checked by a mechanic, but if you're feeling adventurous, you can try tightening the bolts yourself. Just make sure to use the right tools and be careful not to damage any other components.
