I've had my 2018 530e for 20 months. When I first got it the electric range would show 21 after a full charge, 9 months and 10k miles later it was serviced and got a software upgrade and next morning the electric range showed 16, 20 months and 21,000 miles later (this week) got it serviced and a software upgrade and now electric range shows 11 in the morning? I live in Southern California so weather isn't impacting the results due to want vs cold. I don't know if the software is just getting updated to forecast the range more accurately or if I'm actually getting less range? Has anyone experienced this?
