Why does my Audi A8 make a strange noise at high speeds?

I recently noticed that my Audi A8 makes a strange noise when I'm driving at high speeds. It almost sounds like a whirring or grinding noise. What could be causing this and how can I fix it?

It's possible that the noise is coming from your tires. Have you checked them to make sure they are properly inflated and have enough tread? Worn tires can cause strange noises while driving.

Another possible cause could be an issue with your engine or transmission. If you haven't had a tune-up recently, it may be time to visit a mechanic and have them take a look.
