Audi Q7 Auxiliary Fuel Pump 228236005, high-efficiency supplementary part for fuel system.

Directly replace Audi Q7 secondary fuel pump with OEM 228236005 or 7L6919087G; high compatibility, designed specifically for secondary pump location. Its core function is to assist the main pump by delivering fuel from the right side of the tank, maintaining fuel system pressure, especially at high throttle or low fuel levels. Fits Audi Q7. After installation, it can fix symptoms of weak acceleration, starting difficulty, or rough running. If the car stalls with fuel below a quarter tank or there is a buzzing in the tank, the secondary pump is likely aging and replacement will restore smooth operation.
