Refrigerant Circuit, Discharging With A/C Service Station: Evacuate

WARNING: This page is about a different car, the 2014 Volkswagen Touareg, 2013 Volkswagen Touareg, 2012 Volkswagen Touareg, and 2011 Volkswagen Touareg. However, it is still accessible from the selected car via links, so may be relevant.

-- Switch off the ignition.

-- Connect the A/C Service Station to the vehicle service connections according to the operating instructions (refer to the appropriate service information ) and start up the service station.

NOTE:

There is a possibility of refrigerant oil being extracted from the refrigerant circuit together with the refrigerant. To ensure A/C compressor lubrication, the refrigerant oil in the circuit must be topped up with fresh oil. Refer to MAINTENANCE (FLUID CAPACITY TABLES), DIAGNOSIS (2011) / MAINTENANCE (FLUID CAPACITY TABLES), DIAGNOSIS (2012) / MAINTENANCE (FLUID CAPACITY TABLES), DIAGNOSIS (2013) / MAINTENANCE (FLUID CAPACITY TABLES), DIAGNOSIS (2014) .

On vehicles with an A/C compressor without an A/C clutch (with A/C Compressor Regulator Valve -N280-), the engine should run less than 10 minutes with the refrigerant circuit empty and closed (the A/C compressor also runs continuously). The engine speed must not exceed 2000 RPM.

On vehicles equipped with an A/C compressor with an A/C clutch, the engine may be started since the A/C Pressure Switch -F129- or High Pressure Sensor -G65- (checks whether refrigerant is present in the circuit) switches off the A/C clutch as soon as there is no refrigerant in the refrigerant circuit.
