bmw z4 28i m sport 2015 model cant get into the boot no battery inside

[robertlancaster1094]

Could later buy the pass through parts and fit, like i did. It is useful.

thanks for the advice ill probably try that as a last resort

 

[robertlancaster1094]

Well, having forgotten a massive water issue inside of the trunk can be forgotten, of course. :x

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".
E89 are no playgrounds for children.


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

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.

i dont need to get insulted because people are unable to read

 

[robertlancaster1094]

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.

apparently thats my fault cos i need to be an expert on z4s and mechanics in order to own one going by his logic

 

[RobbiZ4]

are you blind or just ignorant?

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.

One final wish:
Learn to quote in a senseful manner.

i screenshotted it all anyway so your pettiness was in vain work on your people skills next time

Robert you have pissed off the forum roof and electrics expert who has helped many on here and probably saved us 10s of thousands of pounds in roof diagnostics and repair. I suspect you are in a bit of a panic, been there myself, feeling totally out of options
Everything he said was a warning to tread carefully things can go from bad to worse if you take the wrong steps. He is German and a bit Direct .
The good thing, he confirms the pin 12 trick which was linked on the first page of your thread should work, so read up on that.
I have used it myself so ask questions if you need to.


*12 April 2024, Just spotted i'm the culprit who wrote pin 15 trick, corrected to 12!

 

[RobbiZ4]

He is German and a bit Direct .

Thanks for this excuse and coronation.

Well, I’m not “direct” because I’m German.
But I will argue very loudly and directly to prevent people who panic from drifting down the path of violence against our beloved E89.

This Z4 needs no chainsaw, no hole digged into the trunk, no violence. It's a little diva with lot's of electronics, which has to be orchestrated.

I'm an electronics engineer.

 

[RobbiZ4]

...you would have to cut through the bulkhead carpet from the cabin..

No, that is not required at all! No violence. :evil:

 

[flybobbie]

Just a suggestion if the person cannot open the boot.
The trim is replaceable, if not up gradable.

 

[RobbiZ4]

Agreed of course, but it's the wrong direction.

To check the tyre pressure, you can also cut it open and measure the volume. They are replacable as well.
It's a valid option.

 

[flybobbie]

i got a mechanic to try everything on it today with the terminals under the bonnet etc and he said im gonna have to contact an auto electrician , also i thought of another idea is it safe for me to cut out the metal panel behind the seats and installing my own ski hatch for boot access

Not needed the hole is already there behind the cabin bulkhead trim, just remove the trim.

Writing stupid now.

 

[flybobbie]

By the way volume and pressure are two different thing.
Something can have volume......but be vacuous...

I would even suggest reason why hole is there, gain access to the boot.
Ski hatch just secondary idea.

 

[RobbiZ4]

An upgrade to integrate the ski hatch is another topic and not required as a roof repair option.

But to get the trunk opened, only two thin wires are required as far as the rear central locking motor is in a working condition. Ignoring this is a valid option.

i did nothing to piss him off he started being rude to me first trying to say i didn't mention the water leak making sarcastic rude comments that's not being direct its just making up lies cos i said in my original post that i had a water leak, he then went on to blame me for the issue all together when the rescue recovery person is the one who told me to remove the battery and as someone who doesn't know and been informed by a mechanic that i am ok closing the boot there would have been no way of me knowing that he was incorrect so if he is just coming on here to bully people due to their lack of knowledge i want nothing to do with him, i took heed of his advice and was good advice and i had no issues with him till he couldn't help but be rude because he didnt read my original post properly

he's clearly got a chip on his shoulder he probs works for bmw or something and helped create this terrible design fault

the 15 pin trick does sound like a good idea my fusebox is behind the glove compartment i checked my manual so ill have a look but might just get an auto electrician in if it looks too confusing im just weighing up all my options so i dont end up spending a fortune and as for anything that involves damaging the car too get in the boot is an absolute last option, but im assuming if the fusebox method doesnt work then there must be something else electronically wrong like the fuse being blown which would mean getting into the boot and putting the battery in is irrelevant would you agree?

Robbi, I am sure you have a good enough sense of humour to take this in the manner it is intended:

It's been quite a while since a Lancaster last upset a German quite this much.

Having read through all this thread, please do understand that there are a lot of people on here who do appreciate your input, listen to what you say and consequently have saved themselves a fortune.
Keep up the good work. Thank you.

PS. I am also struggling to work out why the Pope joined up just to slag you off.
