Genuine Audi Evaporative Emissions System Leak Detection Pump is a genuine OEM component engineered specifically for the Audi A4, S4, and RS4, covering 1.8L, 2.0L, 3.0L, 3.2L, and 4.2L engine configurations including the Cabriolet S4 and high-performance RS4 variants. This precision assembly continuously monitors your fuel vapor system by pressurizing the evaporative emissions circuit and detecting even the smallest leaks that would trigger EVAP-related fault codes and failed emissions tests. Also referred to as the Evaporative Emissions System Leak Detection Assembly, Leak Detect Pump, or LDPump, this component demands exact calibration to function correctly. Aftermarket alternatives frequently use inferior diaphragm materials and imprecise pressure tolerances, leading to false fault codes, recurring check engine lights, and repeated repair visits.
