Well,
Happy days are upon us. I'm pretty sure I cried a little.
Popping out Fuse # 115, waiting a bit, then putting it back in, followed by deleting the app, downloading it (which I had tried many, many times before popping out the fuse) logging in and...
IT WORKED!
Just so you can appreciate why the app is valuable; (which I'm sure everyone already does).
Yesterday I did my 40KM commute, arriving at the office with 48KM left of battery, plugged in when I arrived at work, and went about my day. When I left , I unplugged the car, got in, started it up... and had 48KM left of battery. I had turned on the "charge at off peak hours', so the car never charged. (I would normally check my app during the day)
So, 40KM to home, 48KM of charge. Oh yeah, that can be a bit hard on the heart.
Made it home with 5KM left of battery life.
Still loving my 'i3.
Thanks to all the people that replied, very much appreciated.
