Why is my Audi 80 making a weird noise?

I've noticed that whenever I accelerate, my Audi 80 makes a strange humming noise. It's especially noticeable when I'm going up a hill or driving at high speeds. What could be causing this noise and how can I fix it?

It's possible that there could be an issue with your car's exhaust system. You should get it checked out by a mechanic as soon as possible to prevent any further damage.

The noise could also be coming from a loose or worn out belt in your engine. Have a mechanic inspect your belts and replace them if necessary.
