Suggestion: Can the model year of the car be determined from the VIN? We do that for a few other of the models.

Regards, Mark.

It looks like you might have a 30kWh battery which, in theory, is also supported but you're probably the first to test it. I have a 2016 24kWh Leaf and everything works for me (almost).

In previous model year cars, this hasn't caused any problems but in the 2016 model year they routed the handsfree microphone through the TCU and the microphone stops working when you unplug the TCU. You assistance in this matter is appreciated as I haven't had time to try to override the TCU using the OVMS.
