Volkswagen Golf Service & Repair Manual: 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. |
