Refrigerant Oil Capacities In Refrigerant Circuits For Refrigerant R1234YF

WARNING: This page is about a different variant/trim than selected.

NOTE:

Depending On The Time Period Of Production And The Engine, The Compressor Construction Type May Vary.

Depending on the A/C compressor type, different refrigerant oil capacities may be designated for the refrigerant circuit.

There are different refrigerant oils used for the "Denso" -, "Delphi" -, "Visteon" and "Sanden" A/C compressors. Refer To APPROVED REFRIGERANT OILS FOR REFRIGERANT R1234YF .

For Additional Information About Refrigerant Oil, Refer To REFRIGERANT AND REFRIGERANT OIL R1234yf .

Overview and characteristics for the refrigerant circuit. Refer To OVERVIEW - REFRIGERANT CIRCUIT .

Vehicle Model	Production Period	Total Quantity Of Oil In Refrigerant Circuit In cm³	Quantity Of Refrigerant Oil In Replacement Compressor In cm³	Differing Features Of This Refrigerant Circuit
Audi A5, Audi S5, Audi Q5, Audi RSQ5	From 06/2016	110 ⁺ /_- 10	110 ⁺ /_- 10	A/C compressor manufactured by "Denso" from type "6 SES 14" without A/C clutch or type "6 SAS 14" with A/C clutch

NOTE:

The Capacities Also Apply To The Audi S5, Audi RSQ5 And Audi RS 5.

The Replacement Compressor Contains The Full Quantity Of Oil Intended For The Refrigerant Circuit. If the A/C compressor is replaced, the amount of oil in the A/C compressor must then be adjusted. Refer To GENERAL DESCRIPTION - REFRIGERANT CIRCUIT COMPONENTS R1234yf / REFRIGERANT CIRCUIT COMPONENTS, REPLACING R134a .

At the start of production, mechanically-driven A/C compressors from different manufacturers are installed on all vehicles.

These A/C compressors are available as replacement parts with different oil fill capacities, therefore note capacity on the A/C compressor and the exact part number.

The reason for the different oil capacities inside the A/C compressor is due to the design of the A/C compressor (with or with an oil separator on the high pressure connection) or to the design of the refrigerant circuit if the A/C compressors are have the identical design. Pay attention to the different capacities. Too much oil in the circuit leads to higher pressures and reduces cooling output of the system. Too little oil may lead to lubrication problems in the compressor.

A Data Plate May Be Attached To The A/C Compressor By The Manufacturer, Indicating The Part Number And Refrigerant Oil Quantity.
