Well that's all the diagnostics I can do done, cannot see anything odd and everything checks fine.
Seems the controller J126 is not switching to 12v when commanded.
I wonder if A8Parts would send a known good fan speed controller to me FOC so I can at least rule things out, I cannot trust my original or the other used one I ordered from elsewhere. I would of course pay for or return the part depending on outcome.
I am sitting in the car now writing this, engine is on and the fan is outputting lovely cool air at 3c according to VCDS via solar power of course.
