A/C Compressor

Removing

Special tools and workshop equipment required

Torque Wrench V.A.G 1331 (5 to 50 Nm)
A/C Service Station VAS 6007A or succeeding model.

NOTE:

Flush the refrigerant circuit with R134a refrigerant under the following conditions:
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 an accident.
If pressure and temperature measurements in the refrigerant circuit indicate the likelihood of moisture
In the event of doubt about the amount of refrigerant oil in the circuit.
The A/C compressor had to be replaced on account of internal damage.

The procedure for flushing with R134a refrigerant is described in General Information .

-- Remove the noise insulation under the engine. Refer to Removal and Installation .

NOTE:

Depending on the engine installed, remove the charge air hose.

-- Remove the ribbed belt, refer to [For transmission(s) 0A6, 09M] [For engine(s) CCTA] Removal and Installation .

-- Disconnect the A/C Compressor Regulator Valve -N280- connector.

WARNING:

There is a danger of ice-up.

Refrigerant leaks out if refrigerant circuit is not discharged.

Refrigerant must be extracted before opening refrigerant circuit. If refrigerant circuit is not opened within 10 minutes of extraction, pressure may form in refrigerant circuit due to evaporation. Extract refrigerant once more.

-- Remove the bolts (22 Nm ± 1 Nm) -1- from the A/C compressor and disconnect the refrigerant lines from the A/C compressor.

-- Remove the hex bolts (25 Nm) -2- and the A/C compressor.

Installing

NOTE:

Make sure alignment bushings -3- are seated correctly.
Pay attention to notes for installing A/C compressor. Refer to A/C COMPRESSOR .
