2004 Z4 3.0i Screwed on the right door in less than 1 hour without any problems Tips: Fold up the window, unhook the battery, remove the pillar loudspeaker and door interior paneling, unscrew the airbag and hang it to the side, disconnect the door drive/lock, unscrew and through the Remove the airbag opening. Install in reverse order and yes the threads are unthreaded but the bolts cut the threads and tighten them well. When the door is unlocked, you must close the door to test the electronic lock operation. You cannot establish and check the connection without closing the door because the interlocking function needs to recognize that the door is closed.
