Volkswagen Golf Service & Repair Manual: Important repair notes on air conditioning

Air conditioning systems designed for refrigerant R12 must not be charged with refrigerant R134a until specific conversion measures have been performed → Chapter.
The refrigerant oils specifically developed for R134a refrigerant circuits must never be mixed with the refrigerant oils specifically developed for R12 refrigerant circuits.
Air conditioner service stations which come in contact with the refrigerant must be used only for the intended refrigerant.
Components for R134a refrigerant circuits are identified with a legend or a green label, or are so designed (e.g. with different threads), that they cannot be confused with components for R12 refrigerant circuits.
Within the engine compartment, on the bonnet catch striker plate or in the plenum chamber there is an information plate which states what refrigerant is used.
Different refrigerants must never be mixed together.
  Note
When working on the refrigerant circuit please refer to the information listed under “Safety precautions” → Chapter and “Basic procedures for working on refrigerant circuits” → Chapter.
