Audi Q5: Refrigerant R134a Capacities, Refrigerant Oil and Approved Refrigerant Oils
Approved Refrigerant Oils and Capacities
Note
- As PAG (polyalkylene glycol) oil is highly hygroscopic
(attracts water), opened containers are to be immediately
resealed so as to be air-tight.
- PAG oil from containers which have been open for a lengthy
period is no longer usable.
Refrigerant oil capacities. Refer to
→ Chapter "Refrigerant Oil Capacities".
Refrigerant R134a Capacities
Note
- 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 the A/C Service Station is standing at the same
level as the vehicle (maximum difference: 50 cm) when charging
the refrigerant circuit. If a difference in height is large
enough, a difference between the amount of refrigerant displayed
on the service station and amount actually filled in the circuit
will result (depending on the version of the A/C Service
Station). The ability of the A/C Service Station to perform an
exact filling can change.
- For compressor allocation ("Zexel/Valeo", "Sanden" or "Denso/Nippondenso"). Refer to the Parts Catalog and to
→ Heating, Ventilation and Air Conditioning; Rep. Gr.87; System
Overview - Refrigerant Circuit (vehicle-specific
repair manual).
- Refrigerant circuits converted from R12 to R134a are to be
filled with the quantity indicated in the repair manual "Air
conditioner with refrigerant R12". (This repair manual 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".
Approved Refrigerant Oils. Refer to
