I would still have another look at the clutch and try to nudge it a bit or check the voltage at it when it should be working and when it is working. I know you checked already but maybe check if there is a problem with the low or high pressure switches. You should be able to get an evap temp reading with your scan tool as well. And maybe just concentrate on finding what it causing the aux fan code and don't think so much about the A/C.

I had the same intermittent issue for a year. Except when I bought my E53 it had Both passenger side tires blown out That shredded and ripped the wiring harness coming from the DME, yikes! There were a lot of electrical shorts and melted wires fused together. I had to change the DME and trace the fused wires all the way to the fuse box under the dash. I totally rebuild my AC system from The engine bay to the cabin. My AC system is now working "in part" only because I bypassed the pressure AC Pressure sensor black signal wire. To make a long story short, what I did was Connected the black Pressure sensor wire coming from the DME to the black radiator temperature sensor Wire and I my auxiliary fan and Ac compressor works. Only the drawback to this is the Aux fan will only spin at moderate speed which won't move a lot of air across your condenser when Ambient temperatures Are above 92 degrees while sitting in traffic.

If you can command on compressor with the tool, you should be able to see the evaporator temp drop to confirm its working. It feels like safety is intermittent disable eg loose or short wire from pressure switch.
Unfortunately the pressure switch is not a simple yes no two wire switch So maybe you need to measure the voltage and compare to a working car

The voltage is correct 5V on the multimeter

There are three pins on the pressure sensor
