Hood Secondary Safety Catch - 2011 528i

The hood secondary safety catch on 2011 BMW 528i models with N52 engines serves as the critical fail-safe mechanism preventing hood fly-up at highway speeds. BMW part number 51237165317 represents the complete safety catch assembly, while 51237242576 designates the updated revision for later production vehicles. This component fits all F10/F11 chassis vehicles from 2010-2017, including 535i and 550i variants, though early 2010 production may utilize different cable routing brackets at the radiator support. When sourcing from junkyards, inspect the plastic housing for UV cracking around the spring mount—a common failure point in high-heat climates. Verify the casting mark 'MAGNA' or embossed date code on genuine units. Installation requires routing the bowden cable through the kidney grille support without kinking the inner wire. Lubricate pivot points with white lithium grease during service. If the hood pops but fails to hold in secondary latch position, replace the weakened return spring immediately rather than adjusting the striker plate.
