sorry it took so long to return. Been out of town for work and working daylight to dark.
the only errors I’m having are
9c79 and 9c7a both water valves, in which I have replaced and the error code is still there after clearing.

2f0d radiator blind activation (I don’t believe mine has active radiator blinds)

a36b Bluetooth fault (MULF ) Not sure why that one is throwing. I did replace, program, and code replacement CCC unit but Bluetooth works fine. Minus the microphone and voice control but I was told a code was needed from BMW to reactivate. That is all the codes listed.

im leaning towards a bad replacement valve but all values in analog diag. Are exactly the same as the old one.

Have you tried something as simple as adding refrigerant? It's $35 at Walmart. Easy thing to try.

I’ve tried but something is keeping the compressor valve from opening. The system will not take refrigerant. The system vacuumed down fine and held with no problems.

I still haven’t found any answers. Can anyone help? Can anyone explain or point me in the right direction in understanding what the powersense driversupply is? I’m certain this has something to do with the water valves but I have no clue what. Thanks!
