Question 2004 745I Hydraulic Trunk retrofit need help

Hello From France,

I'm retrofitting a hydraulic trunk system on my 2004 745I E65 which didn't have this option, I bought all parts on ebay and some parts at my local BMW dealer and built the wire harness but I have a very stupid question remaining : how and where is locked the hydraulic cylinder on the LEFT TRUNK LID HINGE ? I can only see the mount for the spring but nothing to attach the cylinder

Could anybody put a picture of the mount on his car ?

Thanks for your help

Thank you for your very fast reply

I bought the special bolt on your center picture then I'm OK for this side, my trouble is the moving part on the right picture, It seems that there is a little axle on your left trunk lid hinge and it is locked on it but I don't have this axle on my car, could you add pictures especially for this side ? I will probably have to drill and install manually an axle then all the pictures or mesurment will help me

I'm happy to see that it is not the same axel that the spring one (but I already tested this solution with unmounting the spring without success for the hydraulic cylinder.

Last one is the connection

This is the other side in case you need it

Make sure the connections on the left side are not leaking, mine are leaking right at the strut, that's why I have it disassembled.

Attachment 484925

This picture is perfect, it's exactly what I needed, In fact hydraulic cylinder is looked on the spring and not on the hinge It's why I was not able to install it

But on mine I don't have the lock axle pin to lock it on the spring and I can't find it on realoem, do you have a reference on it ?

Then I will have to replace my left spring, I understand now why there is lots of references for the trunk springs on realoem.com http://www.realoem.com/bmw/showparts...65&hg=41&fg=60:

23 Spring, trunk lid 2 06/2007 51248223811 ENDED
23 Spring, trunk lid 2 51247201463 $73.60
For vehicles with
automatic trunk lid mechanism
S316A=Yes
23 Spring, trunk lid, left 1 06/2007 51247042104 ENDED
23 Spring, trunk lid, left 1 51247201461 $80.65
23 Spring, trunk lid, right 1 06/2007 51247058646 ENDED
23 Spring, trunk lid, right 1 51247201462 $80.65

But I don't understand why the right spring is different too, does it have any parts attached on it too on yours ?

No parts attached to the right spring it looks like only the left one is the one that has the hydraulic strut on it

I think that springs for hydraulic trunk must be more powerful than mines which has just to open easy the trunk without any oil resistance, I will look for both spring

Install is finished

I bought the special springs at my bmw dealer and in fact there are less powerfull than the original one because the pump is opening or closing then no need for power springs to open, all the job is done by the pump.

Finally install is very easy, you just need the components end eventually the harness to build. all informations about trunk switch close or open comes from the bus and the CANBUS wire can be connected to the ones of the power module near the trunk module then no difficult to do .

Actually the trunk is perfectly working with opening with remote control or any trunk switch, but closing only works from external trunk switch or inside trunk switch but not from the remote control or the driver button. I read that US law didn't permit it, only CEE versions can close from the remote control then I will have to replace my ebay.com trunk module by an European one.

Or may be anyone succed in reprogramming the remote closing with NCSexpert or another software, can you help me to program it without replacing the module ?

Information from the BMW WDS (online) :

Versions par pays

CEE

La fermeture du capot arrière par clé radio est possible. ==> closing trunk from remote control is possible (and driver switch too)

USA/AUS

La fermeture du capot arrière par clé radio est bloquée. ==> closing trunk from remote control is blocked (and driver switch too)

Then it is normal that the US version doesn't close trunk from the remote control.

Have not played with it yet but looking thru the net I found the following. You will have to use ncexpert to code the hkl and vas option, check to see if you can do it. The first is to close the trunk with by pressing the BMW logo and the second is for the windows

Using NCS expert I coded it to close via the fob or by pressing the inside button next to the steering wheel.

Do you have NCS expert?

Yes i am trying to add it but the module is not visible because it is not an original option then i need to add this option to my car but i don't know what number i have to add in ncsexpert to add it on my car, do you know it ?

Then actually no access to the hkl module.

But the hkl module even with a bad vin inside is correctly working.

hello,

IT WORKS !!!

I added the $316 option on my CAS module with NCS expert and modified the option to activate remote closing and dashboard closing and it perfectly works, then even the US version can do it, it just needs to be modified with NCS expert

Thanks for all

Hello from France,

For the wiring, I just ordered on ebay the trunk module with connector (short wires) to have the good size and I just consult on the Wiring Data Sheet (WDS) how to connect with the others : http://www.bmw-planet.com/diagrams/release/en/

If you have other question, I will try to help

Thanks for the info. I checked today and don't have the HKL module so I will need to wire it to the car. Could you maybe post some pictures of your install, like how you connected the CAN cables from the car to the module.

Your help will be much appreciated, thanks!

Also, how many sensors did you have to get? Was it only the one rotation sensor?

HEllo,

Only one rotation sensor, you can see on the following pictures my installation

To avoid installation of the sensor from the up I used a selfdrill screw


You can see the screw


the wiring is simple , it depends of the year of the car then check the WDS


























To connect the CAN BUS, just connect to the power module



Does it help ?

Hello,

Actually my trunk switch is not connected, I just connected a simple switch near the fuse door to activate the trunk (on the green cable of the wiring photo)

From the WDS I found the following wiring for the trunk switch :

PIN 1 : GR/BL : Ground when you open the trunk to light on the red switch and to activate ground on one side of the switch , I think you can take it from the negative RED light of the trunk door
PIN 2 : GR : other side of the switch signal ==> to the HKL module PIN 11
PIN 3 : RT/GE : +12V from power module connector X1856 PIN 1 but I think you can take it from the positive RED light of the trunk door
PIN4 : Not used

To be clear if your color has not the same :
1) When you press your switch, you should have contact between Pin1 and PIN2
2) If you put Ground to PIN1 and +12V to PIN3 you should have the light inside the button.

I think the only one wire to add is from the switch button PIN2 to the HKL PIN 11
