Refrigerant Oil Capacities In Refrigerant Circuits For Refrigerant R1234YF

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

NOTE:

The capacities for the Audi A3 (8V_ or 85_ for china) apply to all versions (Sedan, Sportback, Cabriolet, etc.)

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/Mahle" -, "Visteon" and "Sanden" A/C compressors. Refer to APPROVED REFRIGERANT OILS FOR REFRIGERANT R1234YF .

For additional information about refrigerant oil. Refer to APPROVED REFRIGERANT OILS FOR REFRIGERANT R1234yf / REFRIGERANT AND REFRIGERANT OIL .

		110 ⁺ / _- 10	110 ⁺ / _- 10	"Delphi/Mahle" A/C compressor
Audi A3 e-tron	From 06/2016	120 ⁺ / _- 10	120 ⁺ / _- 10	Electrically-driven A/C compressor With second evaporator in the high-voltage battery heat exchanger Varying refrigerant oil
Audi RS 3 With 5 cylinder engine	From 06/2016	110 ⁺ / _- 10	110 ⁺ / _- 10	"Sanden" A/C compressors with dual belt pulleys and a condenser is installed in another version.

NOTE:

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 APPROVED REFRIGERANT OILS FOR REFRIGERANT R1234yf / TECHNICAL DATA (R1234yf SERVICING) / COMPONENTS, REPLACING (R1234yf) .

Different A/C compressors are installed depending on the vehicle date of manufacture and the engine.

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.
