The rear driver's side door on my M3 LR has developed a fault whereby when you open the door, internal button or external handle, the window drops to allow opening but then goes back up again when the button or handle is released. This means that when you go to close the door the window is all the way up and strikes the chrome (on mine) surround. I have to manually lower the window before closing that door. Only noticed yesterday and of course the passenger didn't realise so now the chrome is scratched but at least the window didn't break. Don't know if it's a bug with the latest software (I'm on 2021.12.25.7) or a faulty door sensor. Service appointment is booked but worth checking your doors just in case it's a wider problem and before anyone tries to close the door with the window up!
