WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Audi SQ5, 2024 Audi Q5 e, 2024 Audi Q5, 2023 Audi SQ5, and 2023 Audi Q5 e. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Connect the A/C service station. Refer to A/C SERVICE STATION, CONNECTING .

Observe the test requirements. Refer to PRESSURES, CHECKING .

-- With the ignition switched off, check the pressures in the refrigerant circuit (using the A/C service station). Refer to Refer to REFRIGERANT CIRCUIT, CHECKING PRESSURE WITH SERVICE STATION .

The pressures with the ignition turned off meet the specifications.

-- Start the engine.

-- Bring the engine speed up to 2000 RPM.

-- Observe the pressure gauge of the A/C service station.

NOTE:

The switching pressures for the refrigerant circuit switches are vehicle-specific.

The connection with the valve for low-pressure switch or at the evaporator is only to be used on vehicles with no service connection on the low-pressure side and with an inaccessible connection on the A/C compressor or reservoir (measuring exactness). Only applies to specific vehicles. Refer to Refrigerant Circuit (vehicle-specific Service Information).
