Some info to help troubleshoot.
Ambient temperature sensor
For evaluation of the ambient temperature, two sensors are used in the deluxe automatic air conditioner and
the four-zone deluxe automatic air conditioner.
Ambient temperature sensor G17
The measured value from the ambient temperature sensor G17 is evaluated by the control unit J285 in the
dash panel insert and transmitted to the Climatronic control unit J255 via the convenience CAN data bus.
Fresh air intake duct temperature sensor G89
This is evaluated by the Climatronic control unit J255.
The ambient temperature sensor G17 is installed in the front end section.
The fresh air intake duct temperature sender G89 is located in the intake housing of the air conditioner unit.
The Climatronic control unit J255 always evaluates the lower of the two ambient temperature values. In the
event of failure of one of the sensors, the other ambient temperature value is adopted. Should both ambient
temperature sensors be defective, a substitute value of 10 °C is permanently assumed.
