Capacity Specifications

Refrigerant R-134a


NOTE: When charging the system on the high-pressure side, always use the maximum amount of A/C refrigerant, as some of the refrigerant remains in the hoses of the refrigerant recovery, recycling and recharging unit.







Refrigerant (PAG) oil


NOTE: The PAG oil used in refrigerant system Part No. G 052 300 A2.







CAUTION!
Part numbers are for reference only. Always check with your parts department for latest parts information.


NOTES:
- R-134a refrigerant oil (PAG oil) absorbs moisture very rapidly. Moisture combines with the refrigerant to form acids which will damage the system.
- Use only the specified oil from a sealed container and ALWAYS reseal oil container immediately after use. DO NOT use oil if it has become contaminated with moisture or if oil container has been left open.
- Use only the specified synthetic oil (Polyalkylene Glycol or PAG) for the R-134a refrigerant system.
- Refrigerant oils used for R-134a and R-12 systems are NOT compatible. DO NOT use the oil for an R-12 system in an R-134a system. If refrigerant oils are mixed, the system will be contaminated and compressor failure may result.
- Use only approved refrigerant oils that have been released into the Audi parts system.


NOTES:
- Replacement A/C compressors supplied by the Parts Dept. are filled with 250 cc ± 20 cc (8.5 fl oz ± 0.7 fl oz) of refrigerant oil. This is the total A/C system refrigerant oil capacity.
- When A/C is switched on for the first time, the refrigerant oil is distributed throughout the entire system.
- When replacing A/C system components, add appropriate amount of refrigerant oil to component, refer to "A/C Refrigerant System Components, Replacing". Service and Repair
- Dispose of used refrigerant oil following laws governing hazardous waste disposal.
