A/C Compressor Regulator Valve -N280-, REMOVING AND INSTALLING, AND REPLACING: Removing

WARNING: This page is about a different car, the 2023 Volkswagen Arteon. However, it is still accessible from the selected car via links, so may be relevant.

-- Depending on the vehicle and the location of the A/C compressor, remove the components that block access to the A/C Compressor Regulator Valve - N280-. Refer to Refrigerant Circuit .

Vehicles with a regulator valve that cannot be access when the A/C compressor is installed

-- Remove the A/C compressor. Refer to A/C COMPRESSOR, REMOVING AND INSTALLING .

Vehicles with a regulator valve that can be access when the A/C compressor is installed

-- Discharge the refrigerant circuit. Refer to REFRIGERANT CIRCUIT, DISCHARGING .

CAUTION:

Danger of frostbite due to refrigerant coming out under pressure.

Frostbite on the skin and other parts of the body is possible.

- Wear safety gloves.

- Wear protective eyewear.

- Extract refrigerant and open the refrigerant circuit immediately.

- If more than 10 minutes have elapsed since evacuating the refrigerant and the refrigerant circuit was not opened, evacuate the refrigerant again. Evaporation can cause pressure to develop in the refrigerant circuit.

-- Remove a refrigerant line from the A/C compressor. Refer to .

Continuation for all vehicles

-- Disconnect the connector to the regulator valve -B-.

Tip

Depending on the design of the A/C compressor, the A/C Compressor Regulator Valve - N280- may be equipped with a short wiring harness.
If the A/C compressor has A/C clutches and a shared connection for the A/C Compressor Regulator Valve - N280-, disconnect the wires to the regulator valve from the connector.

-- Clean the A/C compressor in the area of the A/C Compressor Regulator Valve -N280- -B-.

-- Remove the circlip -A-.

-- Remove the A/C Compressor Regulator Valve - N280- -B-.

-- Check the A/C Compressor Regulator Valve -N280- -B- and the mount in the A/C compressor -C- for dirt.

If the screen -D- or the mount in the A/C compressor -C- is extremely dirty (for example, if there are shavings or there is dark, sticky grit), this indicates that the A/C compressor is damaged. In this case, clean the refrigerant circuit and replace the A/C compressor. Refer to A/C COMPRESSOR, REPLACING DUE TO LEAKING OR INTERNAL DAMAGE .
