Hey everyone, my used Golf 7 from 2016 has started making this weird beeping or "birdie" sound from the rear right wheel. It usually happens when I'm driving slow after being on the Autobahn for a while, and it stops while I brake. There's a circular scratch on the brake disc.

I'm definitely going to see a mechanic, but has anyone experienced this before? Trying to understand what to expect. Also, how much did it cost you?
