I have an AWD M3, purchased in October 2018. I have almost 10k miles on it now.
I only tried supercharging a couple of times when I first got the car for a long trip. No issues at all. I continue to charge at home, and occasionally with a level 2 at work.
My max range has been stable at about 309-310. I usually charge to 80-85% every couple of days.
Things recently changed. I had to use a supercharger recently and it charged fast at 150kw (I think).
After that charge, I am noticing a steep, and continued decline in range over the following 200-300 miles or so. First 1-2%, now to 3%, with my last charge last night only to 255 at 80%, an estimated max range of 300miles.
So, why is this suddenly happening, and is it related to the supercharge?
I tried running it down to 15% and charging up to 95% in case it was a balancing issue. No improvement.
Any suggestions?
