All F20s from PML will have this feature too. Pressing n hold the lock button or remote will close all windows and fold the side mirrors.
Press n hold unlock for s few seconds will wind down the windows. There is a hidden menu in the display in which you can see oil temperature and some funny variables. You can disable dtc and traction by pressing and hold dtc off button. Our radio channels 1-8 is touch sensitive. Touching them without pressing will show you the station details on the idrive.
You can code to enable digital speedo in your speedo panel. Can enable vim, disable seatbelt chimes, default recirculation, default auto start stop memory, enable sports display but not usable as ours is not sports transmission. Etc.
Found all these after fidling with my ride. Used to own VW and do coding via vagcom and also read up on overseas bimmer forums hence some basic knowledge. On other F series, there are more interesting things to explore. Ours has no navigation, cameras etc.
