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 down. I am having to put the i3 thru a emmisions cycle and wanted fresh gasoline in the Tank .With in a few start cycles the Yellow check engine light illuminates. Car is still running perfictley.Checked the gas cap, no change. Then decided to De- activate "hold state of charge and light went out within next start cycle. Car still running perfectly. Anyone have ideas on why its doing this?
