Car has never had scooter motor come on at 6% battery ......its always plugged in before that. It will run throughout an emissions cucle with no "engine light". Gas tank has been filled 2-3 times with premium. Fuel stablzer added twice...6 and 18 months ago.
My 2017 i3 Rex has run perfectly for the last 2 years since purchase. Lowest battery level was 25%. Scooter motor has run some maintenence cycles flawlessly. I have a Bimmercode OBD plug and activated the "range extender " so as to "hold " the battery level and run scooter to bring the gas tank...
