Standard Ignition MAS0352 mass air flow sensor for the 2002-2011 Audi A6 Quattro V8 4.2L measures the air entering the engine and reports it to the ECU. The ECU uses that reading to balance the air/fuel ratio.
A failing mass air flow sensor can show up as a rough idle, hesitation or a check engine light, but other faults can look the same. With the engine off and cool, look over the sensor connector and the intake duct leading to it for loose clamps, cracks or damaged wiring before you replace the sensor.
It is a direct-fit OE replacement for the 2002-2011 Audi A6 Quattro V8 4.2L and is extensively tested to OE specifications.
