A4-2.0T Intake Pressure Air Mass Throttle Angle Deviation?

Hello, according to your description, if there are deviations in the trachea pressure sensor, air quality sensor and throttle position sensor recently, it should be the fundamental problem. Then check the air intake system that the air flow meter started for the first time. The deviation of general air flow meter is related to the diagnosis of all aspects of our air flow meter, and the angle deviation of this throttle valve will appear in special calculation. I hope it helps you.
