Fuel Door Assembly - 2011 528i

For the 2011 BMW 528i (F10 chassis), the fuel door assembly typically wears part numbers 51177203759 or 51177205281. This complete unit includes the hinged door, integrated spring mechanism, and mounting bracket that attaches to the quarter panel. Interchange spans 2010-2016 F10 sedans regardless of engine variant—N52, N55, and N63 models all share this component, making junkyard sourcing straightforward across the model range. When pulling from salvage yards, inspect the plastic hinge tabs for UV-induced brittleness, a common failure point that causes the door to hang loose or fail to latch properly. Verify the emergency release cable attachment point inside the trunk remains intact. Installation requires removing the right rear wheel arch liner to access the 10mm mounting nuts and electrical connector for Comfort Access models. Since BMW paints these doors body-color from the factory, plan for professional blending unless you locate an exact paint code match.
