CLIMATRONIC A/C System With Automatic Control

WARNING: This page is about a different car, the 2007 Volkswagen Touareg, 2006 Volkswagen Touareg, 2005 Volkswagen Touareg, and 2004 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • 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.
  • For deviations from automatic operation, refer to respective operating instructions.
  • If there is a malfunction in the system, first interrogate the DTC memory using the Vehicle diagnostic tester in "Guided Fault Finding" function.
NOTE:
  • 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 service information. Refer to Refrigerant Circuit and Components in General, Technical Data .
