Not sure what year this vehicle is but BMW’s in general do not like to need to be jump started for many reasons I wont go into.
However one of those reasons is the “Power Distribution Panel” that they have… It is usually located in the trunk or on top of the battery and it consists of a rack of flat fuses that protect many circuits in the vehicle. When one of those fuses blow for whatever reason… you have to replace the entire power block … Its an ABSURD design and boggles the mind how or why they used such a thing… when a fuse blows you should be able to replace it…and it alone… not replace all the fuses in the panel just because someone decided that was what they were going to force you to do.
Not certain if you have this panel (which in this case mounts on top of the battery in the trunk), but if it looks like this one I have here next to my computer desk, then when one fuse blows… you are stuck replacing all the others along with it…whether they are blown or not… and thus wasting a lot of money in the process. There was also a similar unit in the passenger side fender well in the trunk that handles other circuits. My point being… look to see if you have this style of fuse block in your vehicle.
Look at your distribution panel… see if its conventional or like this one for an 11’ BMW 530
