Hi, I've had an i3 for about a month.
I intend to monitor the battery capacity through the hidden menu at the start of every month.
When I got the car I managed to access the "hidden menus" on the heads up screen. (hold the button on the side of the screen for 10 secs).
Now, when I try to access the menu I get a message saying "Reset not possible"
Anybody suggest what I might be doing wrong?
