Right Side Curtain Airbag - 2011 528i

The right side curtain airbag for the BMW F10 generation 5 Series (2011-2016) mounts above the passenger-side window frame, concealed within the headliner and extending from A-pillar to C-pillar. Compatible with N52B30-equipped 528i models as well as 535i and 550i variants, this module uses primary OEM number 72127239472, though earlier production may carry 72127202158 or supersession 72127329336. When sourcing from salvage, verify the yellow connector harness shows no green corrosion and the gas generator hasn't been deployed—indicated by an intact tear seam on the headliner edge and absence of burn residue. Interchange spans 2011-2016 F10 sedans and F11 Touring wagons; F07 GT models share the component but require mounting bracket verification. Installation demands battery disconnection and a 30-minute capacitor discharge wait before handling the pyrotechnic igniter. Common failures include connector pin damage during B-pillar trim removal or water intrusion at the roof rail seal. Never test resistance across igniter terminals.
