Hi all,
I have a 2020 G21 M340i xDrive with 19'' wheels (792M) and I don't believe that I have the sound/noise like the one is being discussed here.
I still only have 1.500km in the car, however I've been tracking this thread quite closely and have tested several different options, highway, city, country roads, open windows, closed windows, sport plus, individual, confort, eco. I did found several rattle noises in plastics, the isofix cybex base, but not the grinding sound described here.
Will keep looking for it and updating my feedback here in this thread.
