Well I don't have my car yet - so I cant comment on the new F30. (although there was no evidence of it in the several test rides I undertook (320i / 320d / 328i))
But my existing 120i M-Sport has [or had] the same problem. Squeeking / moving noise on the doors.
After reading about this on various BMW forums, I cleaned the seals at the top of the doors - which is a sort of rubbery felt, and put all the windows down and cleaned the inside of the window seals - where the windows fit into. Lots of black rubbish came out.
End of noise issue - and I think it started after the dealer cleaned the car - and used some sort of silicon spray which meant that it was easier for things to move around.
I now clean these area's every time I clean the car - takes 1 min, and I have never had them re-occur again. The key thing is dont apply slippery things to your door or window seals!
