Software update - unable to set low-cost charging

Thu May 18, 2017 12:41 pm

Just had a software update applied by BMW while my 2017 i3 REX was in for the minor REX recall. Now neither the vehicle nor the app will let me keep the "low cost charging" option setting. The low-cost rate window is still correctly set in my car, and I even changed each value by 1 minute (start/end time) to force an update, just in case that fixed it (it didn't). It lets me select low-cost option, it just doesn't work / respect the setting.

For example, if I park my car for the night and try to set leave time of tomorrow and low-cost charging, the car now resets back to charge immediately after a few seconds. Even if I quickly leave the car, or left-click to accept parameters, before it resets the setting, as soon as I plug in it starts charging. This will be a huge issue (>7x cost per kWh) when peak / summer rates come in, and is already 3x more costly (per my local EV tariff) to charge off-peak vs "super off-peak" or overnight.

I tried to use the app to force next planned trip through with low-cost charging and it will not work either. In this case, the new departure time won't even be accepted at the vehicle now.

Anyone else having trouble with the charge scheduling feature for low-cost? It worked until I got the update last week (w/o May 11, 2017). I'm asking the local dealership who provided the update about this and will post any learnings.

This explains something I first saw yesterday. I tried to use the app to precondition the car and it did not work.
