Climatronic A/C System with Automatic Control






Climatronic A/C System with Automatic Control

The vehicle has a Climatronic with 2-zone right/left temperature control or 4-zone right/left, front/rear temperature control.

Pressing the button "AUTO" will reverse all settings which deviate from the automatic operation.

In "A/C" mode only the A/C compressor is set to almost zero delivery. The heating and ventilation operation continues to be controlled electronically.

If there is a deviation from the automatic operation before ignition is switched off, the selected functions remain permanently stored.

Deviations from automatic operation, refer to respective operating instructions.

If there is a malfunction in the system, first read the DTC memory with the Vehicle Diagnostic Tester in "Guided Fault Finding" function.

Hybrid vehicles have a high voltage system. Danger of electric shock! It will also be necessary to work on the high voltage system when performing the following procedures. Switch off the high voltage system.

The refrigerant circuit should be flushed with refrigerant R134a:

In the event of dirt or other contamination in the refrigerant circuit.

If vacuum reading is not maintained on evacuating a leak-free refrigerant circuit (pressure build-up due to moisture in refrigerant circuit).

If refrigerant circuit has been left open for longer than normal (for example, following an accident).

If pressure and temperature measurements in the refrigerant circuit indicate the likelihood of moisture

If it is not clear how much refrigerant oil is in the refrigerant circuit.

The A/C compressor had to be replaced due to internal damage (for example, noise or no output).
