Rear Seat Bottom Cushion - 2011 528i

When sourcing a rear seat bottom cushion for your 2011 BMW F10 528i, target 2010-2016 F10 sedan donors exclusively—the wagon (F11) and GT (F07) variants utilize incompatible floor pan mounting geometries. The cushion assembly typically breaks down into left (52 10 7 238 938) and right (52 10 7 238 939) sections with a shared center element (52 10 7 238 937). Inspect junkyard units for collapsed foam density at the ISOFIX mounting points, a common failure where child seat pressure creates permanent compression. Check the underside for seat heating elements (two-pin connector) and ensure the pyrotechnic seatbelt tensioner wiring harness is intact. Installation requires releasing front retention clips by sliding the cushion rearward—disconnect the battery first to avoid SRS fault codes when unplugging occupancy sensors. Verify upholstery color codes match your interior trim, as BMW used distinct Dakota and SensaTec materials that age differently.
