Could be your 12V battery. Just a guess. I'm no expert.

2014

2014

If the 12v battery has never been replaced then that is the first place to look for problems -as already advised by nickp. You can get all kinds of weird errors when the 12v battery has died. It might also explain why the traction battery empties while at rest.

I replaced and coded the battery 4 months ago, when I got the warning on the dashboard . Is no error or warning display or the battery discharge .

In that case, check the 12v battery again to be shure, and I hope some of the other members may be able to help you out. Otherwise, if your car is still drivable there is the option of having a diagnose by a BMW dealer.
