Older BMWs - 'many'- will jump fine. Or use a booster box.
My 2012 wouldnt turn over, tried to jump it- no joy. Connected an AGM charger overnight, started the next day. Actually quite maddening.
Its just a car with a 12V system, right? Not quite.
Generally I agree that BMWs arent special; they dont need magic tools or high priests to affect repairs. But there is something odd with this aspect...sometimes... You ignore the POSSIBILITY at your own peril.

It's hysterical to me. I'm telling you what I've done, but folks still like to say it can't happen. Yes, if the battery is REALLY dead, it's harder to start a car with a jump, but guess what, that's true on ANY CAR!
They are 12V cars, but I do agree, electrically finicky because of POOR ENGINEERING by BMW. But you can jump start them with other cars and jumper boxes, amazing news I guess, I didn't realize that would be the most exciting part of the thread.
