    Since this is a DIY category, then you may have better luck in the E36 sub-category forum, however, to try and answer your questions. IF you just swapped out the OBC with another OBC, then the problem is likely the OBC interpretation of the signal, or it is a malfunction. If you did an OBC upgrade, where you spliced the wires, then the problem could be a wiring issue.

    I would likely borrow a friends OBC (make sure it works), swap out OBC's and give it a try first if it works. If it doesn't, you got a faulty OBC. If it exhibits the same behavior, you could have faulty wiring. I would just diagnostic the problem one step at a time. :-)

    Hope this helps....

    i had already thought the above but! : the wiring is good because the previews obc working great...and i have already tested another obc and does the same thing! thats the reason im asking about different programming of the obc...is this exist?

    I have posted some pretty detailed instructions for replacing a 7- or 11-button MID with an OBC, that I wrote them some years back for the BMW CCA Roundel magazine. They don't have a lot of pictures, but they explain many details and offer a number of tips and tricks. The first half of the instructions, on replacing the turn stalk, appeared in 1997.

    As our cars were still new back then, the instructions try to replicate or improve on the factory's work, and avoid anything that could jeopardize the warranty. (I had a contentious German Meister, at the time, who was just itching to deny a claim.) For example, the instructions don't add the CODE function, partly because it is just too easy to defeat, but mostly because it was an added and possibly expensive complication. They also mention dealer coding (which you have to do for an unused OBC) and what "faults" a dealer might see when they run diagnostics: so that they don't draw the wrong conclusions from your work.

    The instructions also have a nifty schematic that summarizes the retrofit on a page.

    One quick question,

    I have a euro E36 323i and i'm currently parting an e36 320i with a 18 button OBC on it.

    My car doesn't have the required plug for the big OBC, but would it be possible to get the wiring loom and everything i need from the other car? Or is it more easy to just wire it by myself?

    Thanks,

    Follow the instructions and do it yourself. There are really four or five new wires you have to drag to locations behind the cluster and/or to the glove box. It is likely harder to remove the original wiring from car that you are parting out then having to add 4 new wires....

    Hi, Paul (brunp):

    So after you found and spliced into the black/green wire on the red connector behind your glovebox, does your CODE feature work properly on your retrofitted OBC? I guess that pin 15 is indeed populated in that red connector, and there is no need to source a properly sized contact?

    Also, for everyone, did your contacts recycled from your extra X1070 (black) OBC connector work properly in the X16 (white) connector on the instrument panel? Or do I need to source the correct Siemens contact (BMW P/N 61 13 0 005 201 - thanks, johnf!)?

    BTW, my car is a '98 M3, currently with an 11-button unit. Thanks very much in advance!

    P.S. OP (delmarco), thanks for taking the time to write and post this up!

    So, I look basically for the black/green wire which delmarco had discussed and found one that goes to the Red connector in behind the glove box, right here.





    Consequently, it is also in slot Pin 15....so I end up cutting the wire, like this:



    I know I can always re-solder it if it doesn't work, but before permanently wiring the connection, I wanted to test it, so I did a open-ended tap on the one end:



    A three way tap on the other:



    and viola, after turning the car on, I get this:

    Answer to question 1: I took the wrong picture. I assumed originally it was for check control, but it was for CODE instead. I did try it a little while later and it does work. I can type in a code, turn off car and then have to enter the code before I can proceed future.

    not sure I follow your second question....regarding contacts....you referring to pushing the PIN into the missing slot in the one instrument panel pin-out? PIN 21, I think or whatever. If so, then yes....recycling the one pin worked....I just had to insert it carefully and used a electronic plyer to push it in to the front.....

    Wow, that was quick! Thanks very much for the response.

    On the second question, yes, that was what I meant, the contact needed to populate pin 21 in the white IP connector. Sorry about the confusion.

    All right, I'm set to do this now. Again, I appreciate the information!

    Hey guys, I am in the middle of this DIY, and have a question.

    When you say "e. Pin Slot 15 (Blue/Purple/White); X17 Pin 24 (Odometer)".
    Do I just splice into the old connection, like the other ones? Or do I splice into the old connection AND X17 Pin 24?

    Thanks, quick response would be appreciated!

    if you have r6 engine and the obc seems to be "miscalibrated", then it means that the obc came from r4 engined car (and vice versa).
    need to get one from r6 engined car...

    In this specific case, the wire from Pin 24 on X17 ends up @ Pin 15 on the OBC connector, so you need to make sure that you just move/splice that wire into the new OBC connector.

    Hope this makes sense.

    Ok, so just splice the Pin 15 to the new connector then?

    Thanks.

    yes.....what occupied Pin 15 on the old connector is spliced to Pin 15 on the new connector....that is all there is to it...

    All the wires from the old collector should go to the same pin-outs on the new connector except for the power/grd which go to the new locations on the second connector that comes with the 18 button OBC kit. If you are coming from an 11-button variant, then you should have one new wire headin' to the glove area and I believe 3 new wires getting routed to the instrument cluster area.

    Hopefully, this clarifies it all. :-)

    Hey Paul,
    I am close to completing the swap, but I have encountered a problem...

    My check-control wont work!. If I press CHECK on the 18 button, the screen just goes black. My pin slots 1,2,3,4,5 on Black OBC connector are all just spliced into thier matching colors at the OBC. Is this correct?

    Also, My temp was initially working, but after re-wiring a few wires to try and get the check control to work, and plugging OBC back in, now the temp doesnt work either!!! (just flashes -35 f....)

    I read somewhere that it may take the temp a while to recalibrate after uplugging the OBC. Do you think that this is the case with mine? I donno, because the F begins to flash, as though its not working at all....


    Ugh, im frustrated...so close to being done...
    Any ideas?
