Volkswagen Phaeton turns on the warm air to generate low power.

There is an internal fault in the sensor. According to the relevant data of Volkswagen, the low power generation when Volkswagen Phaeton turns on the warm air is caused by the internal fault of the sensor, and the low power generation when Volkswagen Phaeton turns on the warm air leads to the increase of power consumption, which leads to the failure of other sensors due to insufficient power supply voltage, so the power generation is low, so it is enough to replace the Hall sensor.
