Its a Z4M. Using a DA is all new to me so am learning as I go at the moment.
BMW clear coat tends to be particularly hard and difficult to correct via DA. You'll probably find something aggressive like FG400 is needed to remove the deeper marks and then you'll need to refine the FG400 finish (mainly if the paint is dark).
I tend to use chemical guys hex pads in orange, green and white paired with Menz Fg400, PO203s and PF106fa
