BMW F10 550i Electronic Shifter Neutral override

This is a quick little procedure on how to engage Neutral on a BMW F model 5 series, if the car has power but does not start.

On my 550i there was no plastic transmission key in the trunk, and there is no way to unlock the transmission under the cup-holder.
Lifting the car, climbing under and dismantling portion of the undercarriage is not really an option on the side of a major highway either.
I did a lot of searching and found a procedure on Bimmerfest from tim330i , which seemed to do the trick. Tim if you ever see this video, Thank you.

The procedure Is:
1. Turn on ignition
2. Press and hold brake, and hold it for the remainder of the steps
3. Press the Start/Stop button (starter will engage)
4. Press the unlock button on the shifter and move it to Neutral and hold it there until a transmission error is displayed.
5. Release the shifter, and immediately re-select Neutral
6. If Neutral is displayed on the shifter you can release the brake and the shifter, now you are in Neutral

To re-engage Park, either turn off the ignition or select Park .

Good luck, this should buy you enough time to pull the car safely onto a flatbed tow-truck. DO NOT tow the car like this without a flatbed, as park may re-engage after 10 minutes or so or if the battery runs low.
