Audi A4 Mass Air Flow Sensor

The Audi A4 Mass Air Flow Sensor has been created to accurately inform the engine computer of the amount of air coming in so that the fuel pulse can be adjusted accordingly, giving it a comfortable output and clean emissions. This Mass Air Flow Sensor is installed in the intake duct, and it measures the true air mass in all Audi engines to allow the PCM to adjust injector timing during changes in temperature or altitude. The vane air flow design applied in early generations of Audi uses a spring-loaded flap connected to a potentiometer, physically restricting flow, which wears out over time, becomes trapped, and causes hesitation or stalls when dirt is present. The majority of current Audi models have changed to the hot-wire style sensor that suspends a heated wire in the air stream, measures the cooling current to determine the flow, responds faster, and does not require the mechanical drag of the vane, although it can be skewed by oil or dust on the wire. Others include a hot film component, which works on the same concept but provides better lifespan as well as reduces heat loss to help maintain the responsiveness of the Mass Air Flow Sensor with time. A polluted Mass Air Flow Sensor or an unmetered air leak will lead the ECU to a rich or lean mixture that will pull on performance and light the check engine lamp. Timely maintenance maintains fuel metering sharp, emission levels low, and the sporty personality that is desired in an Audi intact in any A4.

Choose original equipment manufacturer Mass Air Flow Sensor for great performance and strong durability.
