Refrigerant R134A Capacities: Notes
- From Audi A8 (4N) from MY 2018 the capacity for Refrigerant R134a can be found in the vehicle-specific Service Information. Refer to Technical Data .
When charging the high-pressure side of refrigerant circuits, always use maximum amount of refrigerant (some of the refrigerant remains in the charging hoses).
The specified capacities for refrigerant R134a apply if no other different specifications given for the "S" and "RS".
Make sure that the A/C Service Station is standing at the same level as the vehicle (maximum difference: 50 cm) when charging the refrigerant circuit. If the difference in height is large enough, the displayed and the actual amount of refrigerant added to the circuit may differ, depending on the version of the A/C Service Station. The filling accuracy of the A/C Service Station may change.
For A/C compressor allocation ("Zexel / Valeo", "Sanden" or "Denso / Nippondenso"), refer to the Parts Information and to Refrigerant Circuit (vehicle-specific Service Information).
Refrigerant circuits converted from R12 to R134a are to be filled with the quantity indicated in the Service Information "Air conditioner with refrigerant R12". Refer to A/C System with Refrigerant R134a (This Service Information is only available in hard copy).
Beginning from production year 2006, the name of the "Zexel" A/C compressor was changed from "Zexel" to "Valeo".
