Front Left Door Assembly - 2011 528i

When harvesting a front left door for your 2011 BMW 528i (F10 chassis), target 2011-2016 F10 sedans or 2011-2017 F11 Touring wagons. The core door shell carries BMW part number 41 51 7 234 841 and remains unchanged through the 2014 LCI facelift, though early production (pre-03/2011) may have different window regulator mounting bosses. Always verify the door sticker for option S322A (Comfort Access), as keyless entry doors contain additional antenna wiring that complicates swaps between equipped and non-equipped vehicles. Inspect the lower edge for electrolysis corrosion common on Northeast vehicles, and test the window regulator (51 33 7 253 777) before removal—F10 regulators suffer from cable fraying that isn't visually obvious until powered. Remove the wiring harness intact; the door control module is VIN-specific and requires programming if swapped separately from the chassis BCM.
