@kezo I don’t use the scheduled charging so can’t help I’m afraid. I just plug it in after each use. In all honesty, as the car is always garaged when not in use it never gets that cold and obviously never has ice on it during the winter, so I wouldn’t use pre heating even if it had it so, again, I’m afraid that I can’t shed any light on this issue.
Like you, I’m still finding new things, but one thing that I do miss from the BMW is the physical ‘favourites’ buttons. That was a genius idea and I don’t know why other manufacturers don’t adopt it.
