Here we have a good used fully functioning rear differential control module removed from a 2014 M4 with only 45000 miles, this should fit many m3/m4 cars from 15-20. But make sure you confirm fitment with part number or Vin before buying. It will come exactly as shown in the photos, Im 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.
