Refrigerant Oil Capacities

WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2017 Audi SQ5, 2017 Audi Q5, 2016 Audi SQ5, 2016 Audi Q5, and 2015 Audi SQ5. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

The allocation of the A/C compressors ("Zexel / Valeo", "Sanden" or "Denso") can be found in the vehicle-specific repair information. Refer to OVERVIEW - REFRIGERANT CIRCUIT .

Beginning from production year 2006, the name of the "Zexel" A/C compressor was changed from "Zexel" to "Valeo".

With "Zexel", "Denso" and "Sanden" compressors, the amount of refrigerant oil in the replacement compressor corresponds to the total quantity of oil to be added. On A/C compressor replacement, the quantity of refrigerant oil in the A/C compressor to be installed must therefore be adjusted (an incorrect refrigerant oil quantity will damage the A/C compressor).

When pouring refrigerant oil out of replacement A/C compressor (or malfunctioning A/C compressor), a small quantity of oil generally remains in the mechanically driven A/C compressor (20 to 30 cm³ ). This amount of refrigerant oil does not affect the function of the air conditioner and can therefore be ignored (always remains in A/C compressor). On electrically driven A/C compressors depending on the construction and version a large about of refrigerant oil remains in the A/C compressor when pouring out, so instead of emptying these are flushed. Refer to ELECTRICALLY DRIVEN A/C COMPRESSOR, RINSING (REMOVE REFRIGERANT OIL) .

Following initial switch-on, the refrigerant oil is distributed throughout the entire refrigerant circuit.

The specified capacities for the refrigerant oil apply if no other different specifications given for the "S" and "RS".

For refrigerant oil capacities when replacing refrigerant circuit components. Refer to REFRIGERANT CIRCUIT COMPONENTS, REPLACING . Additionally. Refer to OVERVIEW - REFRIGERANT CIRCUIT (Vehicle-specific repair information) .
