Just curious if anyone has instructions for the lower B-Pillar removal, the plastic piece from the seat beat down to the floor. My new CPO has scuffs/dents/stains from the previous owner and wanted to replace. Since this doesn't seem like a warranty issue but rather a personal issues to replace the damage piece from previous owner. Part is not too expensive ($30) each side. Any help will be appreciated from a former E53 and current E70 owner.
