Special tools and workshop equipment required

Torque Wrench 1331 5-50Nm:VAG1331
Engine Bung Set:VAS6122

NOTE:

Under the following conditions, the refrigerant circuit must be flushed with refrigerant R134a or refrigerant R1234yf: Refer to REFRIGERANT CIRCUIT, REMOVING CONTAMINANTS / .

If there is dirt or other contamination in the refrigerant circuit.
If the vacuum reading does not stay the same when evacuating a leak-free refrigerant circuit (pressure build-up due to moisture in the refrigerant circuit).
The refrigerant circuit has been left open for longer than normal (for example, after a collision).
If pressure and temperature measurements in the refrigerant circuit indicate that there is moisture in the refrigerant circuit.
If there is any uncertainty as to how much refrigerant oil is in the refrigerant circuit.
The A/C compressor had to be replaced due to internal damage (for example, noise or no output).
