Climatronic A/C System with Automatic Control
Climatronic A/C System with Automatic Control
• The vehicle has 2 zone right/left air conditioning or 4 zone right/left, front/rear air conditioning.
• The flow of air and temperature with 4 zone air conditioning for the driver, front passenger and two passengers in the rear can be adjusted within a certain temperature range independently.
• Pressing the button "AUTO" will reverse all settings which deviate from the automatic operation.
• In "ECON" operation 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 --> respective operating instructions.
• If there is a malfunction in the system, first interrogate the DTC memory Vehicle Diagnostic, Testing and Information System (VAS 5051B) in "Guided Fault Finding" function.
• The refrigerant circuit should be flushed with refrigerant R134a if:
• 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 following, for example 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 like noise or no output.
• The flushing procedure is described in the repair information.
