Rear Right Seat Belt Buckle - 2011 528i

The BMW F10 5-Series rear right seat belt buckle (OEM 72 11 9 272 628) secures the outer rear passenger position across 2010-2017 model years, interchangeable with F11 Touring variants but distinct from F07 GT units. To install, lift the rear seat cushion by releasing the front T45 Torx anchors (20 Nm torque on reassembly), then disconnect the microswitch harness if your 528i is equipped with the optional belt warning system. When junkyard hunting, test the latch mechanism for sticky release buttons—a common failure from beverage spills—and verify the plastic housing isn't cracked around the emergency release slot. The left-side counterpart 72 11 9 272 627 shares the same internal mechanism but differs in mounting bracket angle, so avoid mixing sides. Pre-LCI (2010-2013) and LCI (2014-2017) buckles are mechanically identical, though connector colors may vary for the occupancy sensor circuit.
