The plastic backing of my drivers and passenger seat back has separated from the seat. There have been a couple of threads walking through steps to fix this problem. But several of the clips have already gone through this repair process and have now broken. It appears that BMW is no longer carrying these clips from what my dealer found. Is anyone aware of where we can still order these clips and how much they cost. As an alternative, I am seriously considering having them 3D printed. At least this way if others run into the same problem and are not able to purchase the clips, we will have another place to purchase them.
