Fuel Pump Module / Hanger Assembly - 2011 528i

The fuel pump module for the 2011 BMW F10 528i with N52B30 naturally aspirated inline-6 is distinct from turbocharged 535i models that utilize a different in-tank delivery unit. The primary OEM numbers 16117233957 and 16117363072 service this specific 240hp engine configuration, featuring a 5-pin electrical connector and specific fuel line quick-connect fittings. When sourcing from salvage yards, target strictly 2011 model year 528i sedans or F11 Touring wagons, as 2012+ USDM models switched to the N20 turbocharged four-cylinder requiring an incompatible hanger assembly. Inspect the fuel level sender resistance across the sweep range and check the strainer basket for metallic debris or varnish. Installation requires removing the rear seat cushion to access the tank cover—no need to drop the fuel tank. Common failures include intermittent stalling under load, extended cranking, or inaccurate fuel gauge readings typically occurring beyond 100,000 miles. Always replace the sealing ring and verify the electrical connector pin configuration matches your harness, as early production 2011 models may differ.
