Disco 2 ac not cooling

hi all, so a bit of an issue with my ac not cooling. things i hecked/replaced:
1. new ac compressor as it was leaking, replaced with genuine. also replaced drier.
2. new condensor
3. uprated spal fan
4. no serious leaks, topped with gas, low pressure and high pressure seam fine.
5. no error codes from the climate control.
6. ac compressor request and clutch all working well on nanocom.
7. exterior temperature sensor seams to be working.
8. made sure climate control is not on eco, also set it to LO both sides

i will be taking it to the ac guys next week but maybe a heads up of what could be the issue might help a bit?

Is the a/c compressor running? not the belt spinning but the centre of the a/c pulley spinning.
Most a/c is pretty simple, pressure switch sees pressure and allows the relay to send power to the a/c compressor, so a quick test would be to see if the a/c comp is seeing any voltage, low or no pressure means the system will not allow the a/c comp to start.
Are the two pipes to the a/c comp getting cold?

If not fcuk it and get rid whilst you still have your sanity!
