Boot opening (from inside the cockpit - like e85)
I have a door lock solenoid lying about, i keep meaning to have a go at fitting on the arm of the boot mechanism that the boot emergency cable should be attached to. Then lead some wires to the cabin where i could in a emergency unlock the boot. I could wire it to the boot switch i bought and fitted, or even take the wire outside the car.

Seems like a lot of work just so you can push a boot release button once rather than the central locking button twice.
In fact, I have a feeling that, if you have driven so the doors lock automatic, it’s only one push to unlock the boot.
And it’s a button that’s far easier to reach than the standard boot release button location.

An alternate boot opening method could be worth its weight in gold if the normal method of opening became faulty, no manual key opening on an e89 so you would have a problem!Lazza wrote: ↑Sun May 03, 2020 7:27 pm Seems like a lot of work just so you can push a boot release button once rather than the central locking button twice.

I meant flybobbies additional solonoid idea that’s powered by an independent supply?

My initial idea was to just trail the wires from the solenoid to the outside of the car, so that remote power could be used to unlatch the boot.
I suppose an emergency back up for boot latch switch failure is the remote key.
I was looking at attaching the solenoid to the white triangle to replicate the hand pull.

I will play with it tomorrow.

Trailing wires to outside difficult.
But something i noticed below the boot badge when you lift it is a rubber bump stop.
I pulled it out and the fitting is hollow behind.
I stripped out the boot lining.
The metal is solid behind but looking it could be drilled through with a fine drill.
Then a pull cable attached to the white triangle terminating where the rubber was.
Just seems like a lot of trouble for nothing.

Boot opening (from inside the cockpit - like e85)
Finally, had some time to install my Boot Opening switch on my Z4 E89 28i.
Here are the steps i took to complete same. May not be the same for every model. I Take no responsibility for the instructions, This is my effort and may help others to do the same.
Tools needed
Torx bit to remove the Panel in the driver footwell.
Pliers, snips
Soldering iron
Small heatshrink
Sharp Blade
Insulation tape
Automotive wire.
Parts needed
BMW Genuine Wiring Bushing Contact 0 2-0 5 Mmâ² 61130005201 from Lloyds Carlisle BMW via ebay page. This is used to get the signal to the CAS module.
5 SERIES / BOOT LID OPENER SWITCH WITH PLUG 6921846 - ebay. Standard Item - Important to find one with the plug and wiring as easier to connect to. REALOEM Link item number 5 https://www.realoem.com/bmw/en/showpart ... 1319200316
The first module and cable bank you see is the Footwell Module. It has 2*51 pin plugs.
The CAS Module (A149A) you are looking for is Piggy Back onto the footwell module but is recessed so unable to see until you remove the 2 * 51 plugs from the Footwell module. These can be removed by pressing a little plastic spring at the top of the plug and sliding the locking lever to the side. They remove easily
Having disconnected the plugs for the Footwell module, I could see the 41 pin connector X13376 for the CAS (A149A). Same process as above to remove this plug. There is also a Ribbon connector X10318 which I think feeds to the Dash but this does not need to be removed.
you also need to remove the cover from the X13776 plug in order to insert the new connector into PIN location 39. This slides out from one side.
Refer to https://www.newtis.info/tisv2/a/en/e89- ... m/BtXFbKuT for the PIN definition of the X13376
Refer to X13376 connector layout schema at https://www.newtis.info/tisv2/a/en/e89- ... 6/CTVJiEMv
Refer to https://www.newtis.info/tisv2/a/en/e89- ... a/CTBq4FXm for the Switch connector
On my switch, Pins 1, 2, 3 have connection,
Pin 1 is 12 V
Pin 2 is Ground
Pin 3 is FEM signal which connects to the CAS Plug position 39. (using the BMW Genuine Wiring Bushing Contact 0 2-0 5 Mmâ² 61130005201 from Lloyds Carlisle BMW) See below
I used the +12V and GND from the X13376 connector to connect to my switch.
12V at PIN 34
Ground at PIN 12
FEM signal from Pin 39 (This is the signal back to the CAS to trigger the boot latch to open.
I used a meter to ensure connectivety to the switch before reconnecting.
In reverse order
Lessons learnt
Would have been great to have found alternate 12v switched source with ignition, The LED in the switch is on constantly. It is so low in power/visibility, I hope it will not create problems with power drain. If it does I can remove as the FEM signal is a GROUND Connection so no power is needed. It would also have been good to access the ambient light power but the connection to this is under the passenger floor and other web articles have advised against.

- Flexible body of a 15 year old, which i do not have
- Great eyesight, good flashlight.
- Lots of Patience if doing this for the first time.
- Lift steering wheel to its highest position to get as much space as possible
- Remove 3 Torx screws from Black panel in order to remove the Cover and access the wiring behind the dashboard, In order to remove the footwell cover entirely, 3 further steps are required,
- Remove the Bluetooth Module,
- Remove the Speaker cable for Buzzers/Dong
- Disconnect power cable from Footwell light.

- I Inserted the new Pigtail from BMW Carlisle into location 39 on the X13376 and connected this to PIN 3 on my Switch
- I attached my 12 V from PIN 34 to pin 1 on the Switch
- I attached my Ground PIN 12 to Pin 2 on the switch
I used a meter to ensure connectivety to the switch before reconnecting.
In reverse order
- Tidy cables.
- Reassemble the cover and Reconnect X13376 to the CAS Module
- Reconnect both connectors to the footwell module
- Re attach the GND Lead to the Battery
- TEST, TEST, TEST and all going well, IT WILL WORK
- Re attach the Bluetooth, Speaker and Power cables to the Footwell and re attach.

You talents my friend are wasted,if you can go to that trouble and do all that magic to fit a boot switch,you should be working on finding a vaccine for the flu that seems to be going aroundbluetooth wrote: ↑Mon May 11, 2020 11:01 am Finally, had some time to install my Boot Opening switch on my Z4 E89 28i.

This is where it gets confusing and took me a while to get my bearing. I managed to squeeze into the footwell on my back to view what was up there first hand with a torch.
- Disconnect power cable from Footwell light.

How you connect to the cable loom at X13376 is your own preference, I spliced and soldered/insulated each connection. My Preference.
- I attached my Ground PIN 12 to Pin 2 on the switch
I used a meter to ensure connectivety to the switch before reconnecting.
In reverse order
- Tidy cables.
- Reassemble the cover and Reconnect X13376 to the CAS Module
- Reconnect both connectors to the footwell module

Nurse your back and Have a beer or two
- Re attach the Bluetooth, Speaker and Power cables to the Footwell and re attach.

RobbiZ4 - I had read your article and decided against the ambient light route X1019. Time will tell.
Sw4nny....it was not that complicated once you have great articles from members on this forum and others....
