This genuine BMW Leak Detection Pump / LDP Dust Filter (OEM 7177786, also replaces 7439423) is a used OEM unit sourced from a donor vehicle. It monitors the evaporative emission system for leaks and includes the filter element that protects the pump from debris. A failing LDP often triggers a check-engine light and EVAP system fault codes.
