A genuine Audi Leak Detection Pump Hose / Line, OEM part number 4M0201999A, is a used OEM component removed from a donor vehicle. This hose, also known as the leak detection pump line, replaces part numbers 4M0201997S and 4M0201997AA. It connects the leak detection pump to the EVAP system on Audi Q7 models with 2.0L, 3.0L gas, or 3.0L diesel engines. A cracked or clogged hose can trigger an EVAP system leak code or a check engine light, as it is essential for maintaining proper fuel vapor pressure.
