This is documented in a X3 training manual posted on another forum. Going from memory here...there is some sort of lever on the tranny housing that is moved with a screw. This places the tranny in N even with power off. When I get back to my office I'll look it up and see if I can post it.

Even the dealer and BMW road side assistant do not have information on this procedure.
