Right Rear Seat Belt Retractor - 2011 528i

When sourcing a right rear seat belt retractor for your 2011 BMW 528i F10, target part number 72 11 7 264 496 or casting mark 30359974. This component fits all 2010-2017 F10 sedan and F11 Touring variants regardless of engine code—whether N52, N55, N20, or diesel—making junkyard interchange straightforward across the 5-Series range. Inspection requires removing the C-pillar trim panel to access the T50 Torx mounting bolt; check for contaminated webbing, frayed edges, or weak spring tension indicating internal clockspring failure. The standard unit is non-pyrotechnic, lacking electrical connectors—if you encounter a two-wire plug, you've found a tensioner-equipped variant (option 258) requiring different hardware. Always transfer the plastic trim cover from your old unit, as it clips specifically onto the retractor housing. Common failures include sticky retraction from spilled beverages, seized mechanisms from humidity exposure, or cracked mounting tabs from previous removal attempts.
