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.

The special refrigerant oil (for use with refrigerant circuits R134a only) is not commercially available.

Refrigerant R134a and refrigerant oil. Refer to REFRIGERANT R134A CAPACITIES, REFRIGERANT OIL AND APPROVED REFRIGERANT OILS .

-- Discharging, evacuating and recharging refrigerant circuit. Refer to OVERVIEW - REFRIGERANT CIRCUIT , also see USING SERVICE STATION .

-- Operate the A/C system after filling the refrigerant circuit. Refer to A/C SYSTEM, STARTING OPERATION AFTER FILLING REFRIGERANT CIRCUIT .

CAUTION:

Malfunctions due to filling the A/C system with the wrong refrigerant oil.

Only fill the refrigerant circuit with approved refrigerant oils. The correct refrigerant oil depends on the manufacturer and the type of A/C compressor installed. Refer to REFRIGERANT R134A CAPACITIES, REFRIGERANT OIL AND APPROVED REFRIGERANT OILS .

Malfunctions due to improper filling of the A/C system with refrigerant oil.

Too much refrigerant oil in the refrigerant circuit increases the pressures and reduces the cooling output of the system.
Too little refrigerant oil in the refrigerant circuit can lead to the A/C compressor failure due to lubrication problems.

Danger of corrosion in the refrigerant circuit.

Refrigerant oil absorbs moisture. Do not use refrigerant oil from containers that have been left open for a lengthy period of time. Refer to A/C SYSTEM, GENERAL INFORMATION .

Important information:

Refrigerant oil attracts moisture. Close any opened containers immediately after use to prevent moisture from entering.
