According to the instructions, you only have to have the key fob nearby and you press and hold the button on the connector to release. For some reason mine just turns blue, but will not release. If the car has the AC on, then when pressing the light is green (since the car is pulling power), but it does signal the HPWC to stop as you can hear the switch in the HPWC turn off. But no combination, press and hold, one press etc .. allows the connector to come out. I should not have to fish the key out of my pocket to unlock the car to do this, nor should I have to walk up to the front to get the handles to "present themselves" then walk back to unplug. From Page 85 "Note: to prevent unauthorized unplugging of the charging cable, Model S must be unlocked or able to recognize a key before you can disconnect", does the charging port do its own key recognition, or is the fact that I have the tech package which only recognizes when I am at the drivers door the issue?  I am on V 5.9 "106" software, P85+ with almost all options.
