Volkswagen Golf Service & Repair Manual: Converting R12 refrigerant circuits to R134a refrigerant circuits and repairing them (retrofitting)

Volkswagen Golf Service & Repair Manual / Air conditioning system with refrigerant R134a / Statutory texts and instructions / Converting R12 refrigerant circuits to R134a refrigerant circuits and repairing them (retrofitting)

  Note
The laws and regulations listed below are valid in the Federal Republic of Germany. Other or additional laws and regulations may apply in other countries.
Sources in other countries may be obtained from the responsible authorities.
Due to the environmental situation and the consequent legislation, refrigerant R12 is currently neither in production nor available. Refrigerant R134a was developed as a replacement for R12.
However, air conditioning systems developed and designed for refrigerant R12 cannot simply be charged with refrigerant R134a. To ensure trouble-free operation of the air conditioning system following a retrofit, various components of the refrigerant circuit must be replaced.
An exact description of the procedure for conversion and instructions for repair of converted refrigerant circuits can be found in the → Repair manual for air conditioning systems with refrigerant R12 parts 2 and 3. This workshop manual is only available as a hard copy.
