Why is my Audi 80 making a squealing noise while driving?

I've noticed a high-pitched squealing noise coming from my Audi 80 while I'm driving. It seems to be coming from somewhere near the wheels. What could be the cause of this and how can I fix it?

You may have worn brake pads that need to be replaced. This can cause a squealing noise when the brakes are applied. Have a mechanic inspect your brakes to determine if they need to be replaced.

Another possible cause of the squealing noise could be a failing wheel bearing. This can happen due to wear and tear over time. Have a mechanic examine your wheel bearings and replace if necessary.

Check your serpentine belt for signs of wear or damage. A worn or damaged belt can cause a high-pitched squealing noise while driving. Consider replacing it if necessary.
