There doesnt seem to be a physical button or something to press like the e9x platform. Trust me I looked for it. If someone else knows how we can put it into N ourselves, i would i appreciate it too. |

I know on the F10 M5 there is a way to manually do it. Read the owners manual around towing.

Please report back if you figure this out. It would be good to know just in case. BTW I recall in my quick initial read of the manual that it said the can could not be put into neutral without being turned on, but I also think this was in the section dealong with towing. So it might not be 100% apllicable.
One of the reasons I want to know is I have been burned by this before. Once upon a time with my '08 535i disaster (qualified lemon/dealer assisted buy back) the thing broke down on with with a ruptured fuel line right in front of a toll exit by my office. Caused a massive traffic jam for all of my pissed off coworkers. By the time I figured out how to get into neutral without having the car running (since it couldn't start because of the ruptured fuel line) to get towed away by the truck BMW had sent out for me a second tow truck had the car configured on these skate contraptions that attached to the locked wheels. Wound up costing me ~$400 for the tow but if the one BMW had sent out would have taken me in it would have been free. |

There is not a good way to do this. I believe from other internet posts it can be done physically on the trans if you lift the car, but that's not what you're asking.
If you're planning on pulling the ECU, expect the car to be stuck for the duration.

Indeed - here is a pic of the underside where there is a release lever to put the trans in neutral for DCT cars - have never done this and not about to suggest anyone does without more info!!

THIS IS CRAZY. If there is no way to easily unlock park from the cabin then this is a MAJOR flaw of DTC transmissions. This is my first DTC and I took stuff like that for granted. There are SO many scenarios where someone may need to put car in neutral with out power. Can the automatic park engagement after switch off be coded out?

Don't like the thought of blocking a road for over an hour just because you can't get the car into neutral, that's not only crazy but obviously in some occasions extremely dangerous as well. |

I've seen somebody with an e92 M3 race car with DCT rig up a release lever positioned up by the shifter to be able to put the car in neutral. We will probably do something very similar.
But in the meantime for us, we have a battery cutoff switch that allows us to disconnect power to the car while in neutral. Before we had that, and when the car had to go to the cage builder, we disconnected the ground cable on the battery when the car was in neutral. And it stayed like that thru the entire cage build process.

Interesting - good info - so you've tried this on the F8X platform and it works or only on the E9X? Like the idea of a battery cutoff switch - seems like an easier mod for our cars than the more involved release lever.

Yeah, when the M4 we were supporting at the 25 Hours of Thunderhill crashed and ended up on the tire wall, they used a crane and lifted it with a strap under the roof.
The car can have power disconnected while in neutral when it's convenient, but in the case of a crash, especially if the battery safety cable is blown, the car is likely to be stuck in Park.

The problem with the power disconnect while in neutral is that you need to start the car first to get the car in neutral. In the case of a wreck or blown battery cable, you may not be able to get the car in neutral first to then disconnect the ground cable on the battery.
