Delphi Mass Air Flow Sensor P/N:AF10174
Delphi AF10386 mass air flow sensor for the 2003-2006 Audi TT Quattro 4-cylinder 1.8L and other vehicles measures the air entering the engine. The engine computer uses that reading to match fuel delivery to the air.
A failing mass air flow sensor can show up as a rough idle, hesitation under acceleration or a check engine light. Start with a look at the intake duct and clamps for cracks or looseness, engine off and cool; an air leak there can mimic a bad sensor.
It fits the 2003-2006 Audi TT Quattro 4-cylinder 1.8L, which takes one sensor, and the 2003-2004 Audi RS6 V8 4.2L, which takes two. This listing is a single sensor, calibrated and tested to match the OE part.
One mass air flow sensor, probe only. The flow tube is not included.

Is this mass air flow sensor calibrated and tested?
Yes. It is built with calibrated, all-new components, and it is calibrated and tested to match the OE part.
Can hesitation or a check engine light come from a worn mass air flow sensor?
Yes, those signs can come from a worn sensor, along with a rough idle. A shop can read the codes and test the sensor with the engine running.
Is 74-10125 an interchange number for the Delphi AF10386?
Yes. 74-10125 is one of the numbers Delphi AF10386 replaces, along with 06A 906 461 M and 245-1245. The full list is on the Interchange line.
