Based on prior posts I thought I would hear an additional fan when running in Shadow mode. This is our 2nd MS so I know the sounds they make prior to HW2 and all is quiet when I turn off Climate, even with the glove box open. Based on all this input I'm thinking the term Shadow mode refers to the firmware more that what the car is actually doing. No fan would mean the new computer is not On, calibrating and sending info to the net. Would that be accurate?.120 is Shadow Mode.
