This used Audi Leak Detection Pump, OEM part number 4D0906321C, is also called an LDP Filter. A genuine salvage part from a donor vehicle, it monitors the evaporative emissions system for fuel vapor leaks. When this pump fails, it can trigger a check engine light or cause the car to fail an emissions test. It was used in Audi models with 4.2L V8, 5.2L V10, and 6.0L W12 naturally aspirated gasoline engines.
