GWWN87-11340Courtesy of VOLKSWAGEN GROUP OF AMERICA, INC.
  1. Electrical A/C Compressor -V470-
  2. O-Ring
    • Always replace. Refer to the Parts Information for the versions.
    • Coat with refrigerant oil before installing. Refer to REFRIGERANT CIRCUIT SEALS .
  3. Refrigerant Line - Low Pressure Side
    • From the connection point on the right longitudinal member to the A/C compressor
    • With outlet to the high-voltage battery heat exchanger
    • Additional weight on the refrigerant line. Refer to LOW PRESSURE SIDE REFRIGERANT LINE BALANCE WEIGHT, REMOVING AND INSTALLING .
      NOTE:

      An additional weight (balance weight in the refrigerant line to reduce noise) may be present on this refrigerant line depending on the refrigerant line version and the production period. Make sure that this component is not touching or can come in contact with other components during operation (noise). Refer to the Parts Information.

  4. Bolt
    • 22 Nm
  5. Refrigerant Line
    • To the condenser
    • Different versions (with and without connection for the A/C Pressure/Temperature Sensor -G395-). Refer to Parts Information.
  6. Bolt
    • 22 Nm
  7. Outlet of the Refrigerant Line - High Pressure Side
    • To the high-voltage battery heat exchanger
  8. O-Ring
    • Always replace. Refer to the Parts Information for the versions.
    • Coat with refrigerant oil before installing. Refer to REFRIGERANT CIRCUIT SEALS .
  9. Low Pressure Side Service Connection
  10. Outlet of the Refrigerant Line - Low Pressure Side
    • To the high-voltage battery heat exchanger
  11. Refrigerant Circuit Pressure Sensor -G805- Connection
    • Only installed on specific versions (not installed for example vehicles for North America). Refer to the Parts Information.
  12. High Pressure Side Service Connection
  13. Refrigerant Circuit Pressure Sensor -G805-
    • 5 Nm
    • To check, use the Vehicle Diagnostic Tester in the "Guided Fault Finding"  function. Refer to the appropriate Wiring Diagram.
    • Removing and installing. Refer to Refrigerant Circuit Pressure Sensor -G805-, REMOVING AND INSTALLING .
    • Only installed on specific versions (not installed for example vehicles for North America). Refer to the Parts Information.
      NOTE:

      For vehicles with a Refrigerant Circuit Pressure Sensor -G805- or a A/C Pressure/Temperature Sensor -G395-, the Electrical A/C Compressor -V470- version (with the A/C Compressor Control Module -J842-) and A/C control head version (the Climatronic Control Module -J255-) is also different in addition to the pressure sensor. Use the Vehicle Diagnostic Tester in the "Guided Fault Finding"  function. Refer to the Parts Information.

      Depending on the version of the refrigerant line, the Refrigerant Circuit Pressure Sensor -G805- can also be installed on vehicles with an A/C Pressure/Temperature Sensor -G395- in order to close the connection with the valve securely. For these vehicles, the Refrigerant Circuit Pressure Sensor -G805- is not connected to the vehicle electrical system.
