Is your clutch engaging?
The pressures and temperatures in the refrigerant circuit depend on the current operating conditions (such as engine RPM, coolant fan level 1, 2 or 3, engine temperature, A/C compressor on or off) as well as on the effects of outside influences (such as outside temperature, humidity, desired cooling output).
In vehicles with A/C Compressor Regulator Valve (N280) , the pressure is modified on the low pressure side by the valve.
For this reason, values indicated in the following table are valid only as reference points. They are attained at an engine speed of 1,500 to 2,000 RPMs and an ambient temperature of 20 °C (68 °F) after about 20 minutes.
At 20 °C (68 °F) with the engine not running, the pressure in the refrigerant circuit is 4.7 bar (68.17 psi).
I have attached the compressor and condenser replacement procedures as well as other specifications for your reference.
