This is what kills me! So many threads with issues, and then no real outcome or update!

I would say have the codes read and see if you can get live readings of the oil and coolant temperatures as well as the coolant from radiator temperature. There is a temperature sensor at the radiator and at the heat exchanger - maybe one of them is faulty and triggering the ECU to think that the fan needs to be running...
