I was at my dealership this morning, getting the AUX stereo input installed. I asked the manager about the remote window-up issue. She said that it was not something the dealership could enable. I mentioned that this operation was standard on Mercedes in the USA, and in BMW's sold in Europe, and just got a shrug. She then got on the phone immediately, with me standing there, to her "factory rep". He told her "A part is physically removed to prevent this operation on US cars, because of the DOT". He then said what is probably the real truth, as well, saying BMW was scared a dog or kid would get caught in the rising window if done from a distance, where the operator couldn't see.
