Why does my Audi A3 have a high pitched noise while driving at high speeds?

I recently noticed a high pitched noise coming from my Audi A3 when I am driving at high speeds. It seems to be coming from the front of the car. What could be causing this and how can I fix it?

It is possible that the noise is coming from a worn out wheel bearing. You should get it checked by a mechanic as soon as possible, as a worn out wheel bearing can lead to more serious issues if left untreated.

Another possibility is that there is an issue with the brakes. Have a mechanic check the brake pads and rotors for any signs of wear and tear, as this could be causing the noise.
