Hello, I have a 2019 PP. I have a ScanGauge II connected and one of the gauges displayed is the VCM solenoid. I always drive in "D" mode. You are right in that VCM is rarely engaged while in "D" mode. When it does engage, usually under constant very light throttle or coasting, I would not know it was engaged w/o the ScanGauge showing. In other words, I can never feel it engage, and I am trying to feel it! From what I understand it never comes on when in "S" mode but I've never checked. I never drive in Econ mode.
