Standard Ignition MAS0441 mass air flow sensor for the 2012-2016 Audi A8 Quattro W12 6.3L sends airflow readings to the ECU. The ECU uses those readings to balance the air/fuel ratio for clean burns.
A worn or failing mass air flow sensor can show up as a rough idle, hesitation or a check engine light. Other faults can look alike, so with the engine off and cool, look over the sensor connector, its wiring and the intake duct for damage or loose fittings before you replace the sensor.
This mass air flow sensor is a direct-fit OE replacement for the 2012-2016 Audi A8 Quattro W12 6.3L and is tested to OE specifications. This listing is one sensor, and that car takes two.
