V6 TDI

Compressor

Special tools, testers and auxiliary items required

• Hex Ball Socket TORX TB 60 (T40087)

Removing

- Switch off the ignition.

- Drain the refrigerant circuit.

- Remove the refrigerant lines from the A/C compressor. Refer to => [ Refrigerant Lines at Compressor ] Refrigerant Lines at Compressor.

- Remove the A/C compressor from the bracket. Refer to => [ A/C Compressor From Bracket ] A/C Compressor from Bracket.

Installing

Installation is carried out in the reverse order while noting the following:

• There is an unspecified amount of refrigerant oil in the removed compressor so follow the information on replacing the compressor => A/C System with Refrigerant R134a.

- Turn the A/C compressor by hand 10 rotations before installing the ribbed belt on the pulley (to prevent damage to the compressor when it is first switched on).

- Install the A/C compressor on the bracket. Refer to => [ A/C Compressor From Bracket ] A/C Compressor from Bracket.

- Attach the refrigerant lines to the A/C compressor. Refer to => [ Refrigerant Circuit Components ] Refrigerant Circuit Components.

• Coat the O-ring seals lightly with refrigerant oil prior to installation. Refer to => [ Refrigerant Circuit O-rings ] Refrigerant Circuit O-rings.

• Rotating will prevent damage to the A/C compressor when starting the engine for the first from refrigerant oil that may be located in the compression chamber.

- Evacuate and fill the refrigerant circuit.

- Check the event memory of the front A/C display control head, the Climatronic control module (J255) , and erase any displayed malfunctions using the (Vehicle diagnostic tester) in the "Guided Fault Finding" function.

- Install the remaining removed components.

- Operate the A/C system after filling the refrigerant circuit. Refer to => [ A/C System Operating After Filling Refrigerant Circuit ] A/C System Operating After Filling Refrigerant Circuit.

• Note the information regarding operating the A/C system after filling.
