Rear Parking Sensor Set - 2011 528i

When sourcing BMW F10 parking sensors for a 2011 528i N52, target part numbers 66209270501 or the updated 66209397477, which interchange across all 2010-2017 F10 sedans and F11 wagons regardless of engine specification. Junkyard inspection requires checking the sensor face for stone chips and the 3-pin connector for moisture corrosion—common failure points that cause false proximity alerts. These sensors are painted-to-match from the factory, so expect to repaint salvage units; the mounting clips are fragile and often break during bumper removal. Installation typically requires dropping the rear bumper cover to access the rubber grommets, which harden with age and may need replacement. The BMW PDC system is self-calibrating, but verify operation before final assembly: a healthy sensor emits audible clicks when the ignition is on. Note that while F07 5-Series GT sensors carry similar casting marks, they utilize different retention rings that may not seat properly in F10 bumper covers.
