A genuine OEM Audi Leak Detection Pump / LDP Filter, original part number 8R0906621B (also replaces 8R0906621C). This used unit is the EVAP system component that monitors the fuel tank for small vapor leaks. When it fails, the most common symptom is a check engine light with a small leak code, often caused by a clogged internal filter or pump failure.
