    Use NCS Dummy to disassemble the E38SGET.000, open up the E38SGET.000.Text file, and add the following two lines below the LCM.C18 entry

    Code:
    SGAUSWAHL_VMSGBD : "LCM" "C19" "A_LCM" "C_LCM3" "LCM" "004" (S015B,S013C)+!S012C+!S018A {} // (LCM_CI_19,PU01)+!LCM_IV+!LCM_CI_20
    SGAUSWAHL_SGBD : "LCM" "C20" "A_LCM" "LCM_IV" "LCM" (S012C,S018A)+!S018B {} // (LCM_IV,LCM_CI_20)+!LCM_CI_21
    Use NCS Dummy to reassemble that file. Copy LCM.C19 and LCM.C20 from your E39 or E53 folders to the E38 folder, and see if it works.
    Im assuming I will need an LCM4 with those coding indexes? Were these parameters pulled from one of the e39 and or e53 file? Terra, with your instructions it is now showing the additional coding indexes available under the e38 chassis in ncs dummy(obviously because you're a genius) next step is to get an LCM4 with these coding indexes and try it. Back to my question of how to determine the codingindex off of the physical LCM4?

    @ Purplecty The way I did it if I remember correctly was that I hooked up the LCM 4 to NCS and basically read the module. Once it finishes reading it, it does tell you which LCM is and codeindex

    Anyway to tell what coding index this is before I plug it in? Either way I will install everything and attempt to to program it since I have ready modified the the setup per Terras instructions to pull in the additional coding indexes and will post back. Not exactly sure when I will have the time may try this weekend...

    You need an LCM C24.
    LCM C23-C22-C21-C20, will NOT properly work with your E38.
    Beside, don't bother to the auto/manual LWR you can code it with NCS expert after.

    Here my note about the several versions of LCM when I was trying to do the same thing as you :



    If you want a LCM C24, you need to find the two last.

    EDIT : my LCM C24 is the last one (6 961 141)

    You don't need a C24. Officially C19 and C20 won't work, but they should if you properly do the mod I described above.

    Worst case it should be possible to get C20 to work by looking at how a C21 should be coded and handcoding the right parameters.

    Actually digging into it, the C20 file needed a bit of modification to load properly. In this case I think it'll be easier to just upload the compiled versions.

    Remove the .txt from the end of the file, open the resulting zip file, and extract the contents to your C:\NCSEXPER\DATEN\E38 directory. Overwrite as necessary.

    Brief explanation of the files inside:
    LCM.C19 = Unmodified LCM.C19 file from E39/E53
    LCM.C20 - Basically there were some parameters in there that the E38 data didn't have any "default" coding information for. So I either hardcoded the correct value or replaced with the equivalent lines from LCM.C21 where appropriate.
    E38SGET.000 - same changes as described in my earlier post
    E38SGVT.000 - Added entries for the new LCM variants. Not sure if necessary, but shouldn't hurt

    Thanks again! I did as instructed and will try and install and program mine this weekend and post back for my findings and results...

    No, it was beyond frigid and rainy this weekend and I did not get around to it. I do not have a garage of my own so it may be this weekend if the weather permits...

    did you copy over all the files to C:\NCSExper\Daten\E38?

    Yes' it errors out very quickly like its rejecting the LCM all together. NCS wont even read it gives the same error so im not entirely sure what coding index I even have...

    Try the "codierindex_lesen" job. And if that doesn't work, try manually setting entries below and try reading it.



    If that still doesn't work, you can code it like this, though it's a little convoluted:

    Click on "Basic functions" and click 'coapiGetNettoDataFromCbd', and enter LCM.C20 for CBD-Name

    Now load an E39 or E53 ZCS (literally any E39 or E53 ZCS is fine), go to the LCM module, and under "Basic Functions" hit "coapiGetFswPswfromNettoData"
    Under Nettodata-file enter "nettodat.trc"
    and for resultfile enter "FSW_PSW.MAN"

    Code the LCM

    It should now be coded with the appropriate parameters for an E38.

    The Codierindex_Lesen job did not error out and ended quickly but what does that do? What is the next step as I've never used this job...

    Tried all these steps with the same error results. Weird that it wouldn't even program using the steps provided using the e39 zcs. It still rejected the ecu identification...

    I gave up and put the lcm3 back in...

    I'm still convinced it's doable, but maybe it'd be best for me to get one on hand myself and get it working on the bench using an E38 profile

    If you're okay with me taking my time with it, that could work.

    Its useless to me at this point so I am fine with that. Just PM me an address. I have already changed it to my VIN and IKE mileage...


    Looks like the one I got is one of the non compatible for e38 ones. Even if you get it coded to the e38 zcs, would I be able to customize any of the lcm options later on my own?

    I ordered a 6961141 from eBay since this one seems to be the one everyone has positive results with... I'd still be interested in sending this one off to you (Terra) for additional e38 testing...

    So 6961141 is a C24 coded successfully. Where can I get a new windshield bracket for the RLS sensor?
