Why is my Audi A5 making a humming noise while driving?

I've noticed my Audi A5 making a constant humming noise while driving at speeds over 50 mph. What could be causing this and how can I fix it?

Your Audi A5 may be making a humming noise due to worn out wheel bearings. It's important to get this checked and replaced as soon as possible, as faulty wheel bearings can lead to loss of control while driving.

It could also be caused by an issue with your tires. Check for any uneven wear or uneven tire pressure. If the tires are the issue, make sure to get them replaced or rotated to avoid further damage.

Another potential cause could be a problem with your exhaust system. Check for any leaks or damaged parts and get them repaired as soon as possible.
