    • There are different versions. Refer to the Parts Information.
      • A/C Control Module -J301- for manual A/C system
      • Climatronic Control Module -J255- for automatic A/C system
    • To check, use the Vehicle Diagnostic Tester in the"Guided Fault Finding"  function. Refer to Wiring Diagram.
    • Removing and installing. Refer to Heater Control Module -J65- /A/C Control Module -J301- /Climatronic Control Module -J255- DISPLAY AND CONTROL HEAD, REMOVING AND INSTALLING .
      NOTE:

      If there is no Humidity Sensor -G355- installed on vehicles with a A/C Control Module -J301-, a permissible stop time is currently calculated by characteristics curves which are influenced by the measured outside air temperature, the "recirculated-air mode" function and operating status of the windshield wipers. The calculated time must be greater than 20 seconds so that the stop function is permitted by the A/C Control Module -J301-. The stop time can be shortened at a lower exterior temperature, when the recirculating air mode is active and/or when it is raining to prevent the windshield and door windows from fogging up. If the calculated time for the Stop function is less than approximately 20 seconds, it is prevented.

      An neck heating is offered as optional equipment for the A3 Cabriolet. For vehicles with neck heating, there is an additional vent installed in the seat, and there are additional buttons to switch the neck heating on and off in the Climatronic Control Module -J255- A/C control head. For additional information HEAD AREA HEATER .

      There are different versions of the Climatronic Control Module -J255- for vehicles with or without a high-voltage system. For vehicles with a high-voltage system, there are different versions, for example on vehicles for Europe and the North American Region.

  7. Infrared Sensor
    • For determining the temperature in the vehicle interior
