I can confirm that the wiring harness in the 82712157704 kit has the wrong terminal for the bumper sensor on a 2015 X3 (and most likely the 2014 based on what I can find). The stock plug has 12 pins where the kit harness has 6 pins. As the harness is just an extension for this plus through the weather grommet, I am considering cutting out the extension from the harness and using the vehicle plug as is. A new harness will run almost $400 delivered and if this is the only change needed, then it's not worth it. My concern now is I have no idea if the control module is correct for the 2015.
