If the climate control unit has been replaced, or a new position motor for the temperature damper has been installed, a basic setting must be performed. When the climate regulation basic setting is performed, the control unit learns the positioning motors end positions and calculates a new value for the inlet air fan.
Note:
During the basic setting the displays for the "comfort" variant turns off for the climate control panel. For the "basis" variant the ECON button starts to flash.
Test prerequisites:
The battery voltage should be above 11.5 V.
Ignition on, engine off.
No fault codes should be stored in the fault memory.
Correctly installed and connected.
Performance:
Choose the function: Climate regulation.
During the basic setting the text "adapt" is present. After that the text change to "XX Volt" and end with "OK" when it is finished.
Wait about 20 seconds (new values are being stored).
End the function. Switch OFF/ON the ignition, wait about 15 seconds for possible fault codes to be stored.
Re-establish the communication and check if any fault codes have been stored.
If the function fails, check test prerequisites and repair possible fault codes.
