add additinal codes to 2011 x5m
BMW just re-flashed or programmed my x5 today, so the prior owner had it where you can push 1 button to open trunk and again to close it (still works)
what DOES NOT work is I can put the windows down with the key fob, but i Now Can NOT put them back up
how do i go about and add all these cool features back to my car
thanks
