Volkswagen Workshop Service and Repair Manuals

The special refrigerant oil (for use with refrigerant circuits R134a only) is no longer obtainable on the refrigerant/machine oil market.

* This quantity of refrigerant oil is in a replacement compressor and equates to the capacity.

Further information:

The refrigerant oil is very hygroscopic, therefore opened containers must be closed immediately after use to stop ingress of moisture.

Refrigerant oil, because of its chemical properties, must not be disposed of with engine oils or gearbox oils.

Oil distribution

The oil is distributed through the refrigerant circuit, which is located in the sump of the compressor before initially switching the air conditioner system as follows:

• ◆ Compressor     approx. 50%
• ◆ Condenser     approx. 10%
• ◆ Suction hose     approx. 10%
• ◆ Evaporator     approx. 20%
• ◆ Fluid reservoir     approx. 10%
