Mine does a discreet bleep and flashes the indicators on lock/unlock. I have never heard about that bleep being illegal. You cannot have auto or remote close on the rear flap coupe windows as there is no safety switch on them. They will close if you hold the key to lock in the door. It also locks the doors at 8 mph. If you want to know anything about BMW electronics, ask Jason at BW Chiptune, he has a new re-map available. I have no connection with the buisiness, its just they have been good so I will recommend.
