Rear Seat Backrest - 2011 528i

When sourcing a rear seat backrest for your 2011 BMW F10 528i, target 2010-2013 5-Series sedans exclusively. The correct left-side assembly carries BMW part number 52 20 7 203 375, while the right side is 52 20 7 203 376. Always verify the donor vehicle is a sedan (F10), not the F11 Touring wagon, as the folding mechanisms and mounting brackets differ significantly. In the junkyard, inspect the 40/20/40 split-fold release cables for fraying—a common failure point—and test the center armrest latch operation. Installation requires removing the rear bottom cushion first (pull forward sharply), then disconnecting the battery if your 528i has heated seats (SA 494) to avoid airbag faults when unplugging the harness. Check the stamped JCI supplier codes on the frame rails, as these survive fading better than BMW stickers. Finally, confirm the leather color code matches your interior; BMW used multiple black variants (LCSW, N5SW) that appear identical until installed.
