Why is my Audi 80 making a rattling noise when driving at high speeds?

I recently noticed that my Audi 80 starts making a rattling noise when I drive at high speeds on the highway. It doesn't happen at lower speeds or when I'm idling. Any ideas on what could be causing this and how to fix it?

There could be a few reasons for this rattling noise, but one common culprit is loose or worn out exhaust hangers. You can check and tighten them yourself, or take it to a mechanic for a quick fix.

Another possibility is that your exhaust system has a leak, causing the rattling noise. You can try using a sealant specifically designed for exhaust systems to fix this issue.
