Rear Seat Assembly - 2011 528i

When sourcing a rear seat assembly for your 2011 BMW F10 528i, target 2011-2016 F10 sedan donors exclusively. The rear seat group consists of three primary components: the cushion base (52-20-7-294-669) and left/right backrest sections (52-20-7-294-671/672). Inspection priorities include testing the split-fold release cables (common fraying at the handle), verifying heating element function (check for 9C78/9C79 fault codes), and examining leather side bolsters for entry wear. Installation requires disconnecting the battery before unplugging seat modules to avoid airbag light triggers. Remove the lower cushion first (four T50 Torx bolts) to access the backrest mounting points at the C-pillars. Note that while the foam and frame interchange across all F10 sedans, the upholstery color code must match your interior trim. Heated seat variants have additional 4-pin connectors under the cushion that must be transferred if swapping to a non-heated chassis.
