When I say working - I mean that the park heating comes on when I tell it to. Ie the FBH turbine spins up and the internal fans also turn on to push the heat into the car.
After approx 18 mins it is then all shut off (as per spec of the revised software).

The outside temperature while I have been testing each morning has been around 12c. As I understand it, if the outside temp is >= 15c then the parking cooling is engaged where as if below 15c then park heating kicks in - the user cant choose for them self.

Of course there are other parameters I guess - eg is the coolant temp already high?, no low fuel warning etc etc..

sounds promising. I had issues when the FBH occasionally did the full 17 mins 50 seconds....
like when it had just been on a charger !
left to the car's own systems it would mostly do 8 or 10 minutes.
