I'm not sure about the 2er, but we ran into this problem after my wife's 2012 328i got rear ended with enough force to activate the battery cutout. The answer appeared to be "You don't". The tranny needs a running engine to shift. There's theoretically a way to do it from beneath the car with a socket wrench and long extension. But that's not realistic when stuck on the side of the freeway.
The tow truck operator got the car on and off the (flatbed) truck by bouncing the bed and winch controls so the tires skipped on the way up and down. The best way I can describe it was "dribbling" as in basketball. This was obviously not the first time he had done that. Believe it or not, there was no transmission or other drive train damage. But we were pretty amazed at the design decisions that created this problem in the first place. |

Information appreciated. Does anyone know if using the jump start points under the hood allow the engine to be started and electricity distributed to the entire car with a blown IBS? The 'mechanical' method is a joke and only applicable to a dealer shop. My Jaguar has the same transmission and provides a lever attached to a cable under the hood that releases the parking pawl.

No kidding. I didn't actually see it go on the truck, but I saw it coming off. I fully expected that insurance would have to replace the transmission, but it's been fine. |

You can start a car with activated IBS by simply putting a screw driver between the IBS cable and the battery head.

So, unfortunately I don’t have any car at my disposal which currently has an activated IBS and since there is no going back on that I cannot show you the exact steps before I destroy someone else’s. However, in the attached picture that I took you can see the cover is riveted to the battery head, you need to break those pins in order to remove that side so you can access the IBS. When the IBS cable is being replaced they are going to do this no matter what so it shouldn’t be a problem. After removing the cover you’ll see the are that IBS as opened in between the battery and itself, this is where you should put the screw driver in. In some rare cases you can start by just jump starting it using the heads under the bonnet as well. If you want you can try this first and then move on to the screw driver level. If you want guidance I can help you after removing the cover, just upload pictures for every step and I’ll do my best explain it to you.
