I just got a 2019 i3 after owning an used 2015 for 2.5 years. I really liked the aftermarket "hold state of charge" that I got from dvdinmotion for my 2015. It would be very useful for a 2019 given the extended range it will be a challenge to burn up the gas. Dvdinmotion doesn't offer this code any more: is Bimmercode a good alternative? I'm tech competent, but not a coder by any stretch (I can follow a recipe). So need something fairly idiot proof. Thanks in advance for suggestions. Best, WB
