3 the interior panel to remove.
20 is the no pass through option, 21 pass through option.
You would need to cut through the square bulge on 20.
I don’t think you can remove the inside rear bulkhead trim without access too the boot ?

Why oh why didn’t BMW fit a boot release button somewhere in the car or even a key lock in the boot lid somewhere like the previous Z4. This sounds like an absolute nightmare. I hope you get it sorted somehow without too much damage to your car.

Like i said, in desperation, you would have to cut through the bulkhead carpet from the cabin.. It's molded fibre.

Fitting the switch i have done i can open boot now if say roof fails in any position. Access to boot required to access pump screws to dump pressure to manually move roof.

Hey Robert, what you are doing there without any knowledge of the car and a mechanic, who doesn't even know anything about the car's electric/electronic system is:
HARAKIRI

Absolute no recommendation to do anything by yourselve with that huge lack of knowledge!!

Search a garage with a minimum of understanding of these full electronic cars to not loose thousands and thousands of bucks with your current "strategy".

Yes, the red box next to the battery is a fuse box for higher currents. Even the terminals will be routed through it. Due to the "forgotten" watter issue this box might have been destroyed as well.

This might be an option and can be tried out:

Put the negative terminal of a loaded battery onto earth, i.e. the terminal screw under the hood. But not on the terminal with the red cap!!!

Then you can connect the plus 12V from the battery with a tiny wire into the hole of pin12 of the correct(!) black 54-pole sliding plug taken off below of the junction box. It only needs half a second to get the central locking motor activated.

Making any fault with this operation will kill your car - fullstop.
are you blind or just ignorant? i stated in my original post on here that i had a water leak and explained everything and also explained why i removed the battery because the rac rescue man that was called out informed me that i would be able to remove it

just made an account because i read what you said about this not being a fault of the designers, which good design relies fully on technology to do something as simple as opening the boot but also not having a mechanical backup for it? many things could break that prevent the boot lock from opening electronically not just taking out the battery. It's a bad design and everyone knows it, simply blaming the people for being stuck in this position in the first place when it shouldn't be a problem is extremely stupid RobbiZ4.

Poor show. You only joined this forum as you had an issue with your car. Members are trying to help and give you advice and they don't need to be insulted for it.

Yea, you are right.
Will drop all my hints. Would be nice, if you'd drop my quotes as well.

Good luck destroying more of this nice car.
