Why is my Audi A4 making a loud humming noise?

I recently started hearing a loud humming noise coming from my Audi A4, especially when accelerating or turning. What could be causing this and how can I fix it?

This could be caused by worn wheel bearings, which can create a humming noise when they get old and need to be replaced. It's best to take your car to a mechanic to diagnose and fix this issue.

Another possible cause could be a damaged exhaust system, which can create a loud humming noise and affect your car's performance. I suggest taking your car in for a thorough inspection and repair if needed.
