Here we have a communication box module, with part number 84.10 937179101 on it removed from a 2015 M4 with only 7740 miles, Great shape. If you are not sure if it is correct for your car please cross reference it with the vin number listed below. I'm also parting out the rest of the car, so If you need anything please send an email so I can list it on ebay for you.
