    The M5 cluster retrofit

    ------------------------------
    UPDATE: FEBRUARY 2014
    ------------------------------
    Since upgrading my OEM wheels from 17" to 18" my dsc light no longer comes up
    Must have to do with wheel's revolution/distance
    Settings related to this might be stored in the cluster or DSC module
    ------------------------------
    UPDATE: NOVEMBER 2013

    ----------------------------------


    After a few more work on with other peoples e39, I noticed the following:

    The DSC light does not appear and works as expected if the IKE module (Cluster) is coded with NCSExpert only.

    What I did recently on a 1998 535i are the 2 steps below only.

    - Wrote the car's VIN number in the cluster (IKE module) using BMW Scanner 1.4 (Could be done with Tools32 most likely too but I have not tried on this cluster yet)
    - Ran NCSExpert in ExpertMode, select the IKE module, then selected the job to be : SG_CODIEREN then ran the job. This fixed the temp gauge/RPM. The car was manual so I do not know if this is enough to show the gear numbers if your car is manual.

    That's it. Those 2 steps only and everything works, except the oil temperature. No tamper dot. Coolant temperature/gauge working fine.

    I tried to recode my IKE module with NCSExpert, no luck, my DSC light still comes on after 2-3 miles and stays on until I turn off the engine. If anyone has a solution, please let us know.
    -------------------------------------------------------------------------------------------------------------------------------------------------------







    What car will that work:
    Any e38, e39 and e53 but it seems only TU engines with DME 7.x from 09/1998 are capable of sending the oil temperature over the CAN bus.



    Seriously?

    Well you can fit the M5 cluster on an older model, but you won't get the oil temp and nice red lights to light up on the RPM gauge.

    What do I need then?

    - M5 cluster.
    - A computer with XP/Vista/7
    - BMW Scanner 1.4 from PA Soft and the compatible interface/plug.
    - NCS Expert/Dummy and the usual BMW tools (Precise software and steps to be determined)
    - Screwdrivers to remove your cluster.
    - Access to a local specialist in mileage correction that has the right tools. The chip that contains the stored mileage, called M35080, can be recoded, with the right tool, not need to replace it.
    Most likely the cluster you are going to pick will have a different mileage than your own cars.

    The easy way: Autologic
















    The hard way

    1. CLUSTER REMOVAL

    Remove your current cluster.
    [pictures]

    2. M5 CLUSTER INSTALLATION

    Install the new cluster. Once installed, turn your key in position 1.
    Voila, 1st look at your new M5 cluster. This is what you will see after you take the car for a spin. The DSC light will stay up, the coolant temp's needle will go up ton 3/4 (Don't panic this is normal, well for now), and the tamper dot will be on too. The fact the tamper dot is on is because the VIN coded in the cluster is different from the one in the LCM. The tamper has nothing to do with the mileage difference between the modules.

    1st observations:

    Is working fine:
    - Gas gauge
    - Speedo gauge
    - RPM gauge

    Is NOT working fine:

    - Oil temperature and red/orange lights around the RPM gauge: Not working. You only see the last 2 lights, which normally indicate the car can be driven at full speed.
    - Coolant temperature: Not reporting correctly. Goes up to 3/4. The reason why is that the M5 uses a double sensor to monitor the coolant temperature.
    - DSC light: Goes on as you as you drive a few hundred yards. Can not be disabled manually (By pressing the button)





    3. CODING

    Turn you key to position 2 and plug in your PC to the OBD port (I or II) and start your BMW Scanner.
    [pictures to be added]

    When you start BMW Scanner, you will be presented with the car identification screen.
    As you can see, the IKE information on the left contains this poor M5 data (I wrote over as I forgot to take a screenshot)
    The data will be highlighted in red too by BMW Scanner to highlight the difference from your IKE (Your instrument cluster) and EWS module (Alarm basically).



    As you can see, on the left you see the IKE data. It is showing your car is a M5 with S62 engine etc. Obviously it is not. So we need to change that.

    3.1 Go to the top menu: Units > IKE (Instrument cluster instrumentation in english).
    You will be presented with the following menu.
    Have your VIN number handy, the last 7 digits.

    Now click on Reprogramming on the left, the Used Module Reprogramming will then popup. Click on Write FGSTNR (No idea what that means). You will be asked to enter your VIN. Make sure you enter it correctly, then press ok. At this stage, the new VIN has replaced the previously recorded one from this poor dead M5.
    Now the cluster will "reboot" and the tamper dot has just vanished.



    The tamper dot is now gone. It was underneath the "miles" text in the middle of the cluster.



    3.2 Copy the ZCS info from your car to the new cluster. The ZCS is a unique identification code that matches the level of options your car had from the factory.
    Same idea as the step 3.1, click regrogramming then copy ZCS/FA. You will be prompted to copy from the car to the IKE and from the IKE to the car.
    Make sure you select "From the car to the IKE". Click ok. Again the cluster will reboot.



    3.3 Go back to the main screen of BMW Scanner. On the left column, click the Car identification. As you can see now, the IKE shows your actual car. Now the IKE is synced up with the EWS. In other words, the cluster now knows it is installed on a 540i




    4. MILEAGE CORRECTION

    Now, mileage correction. I don't have details on this, I don't have the tools. But I found a guy locally that has the tools. He had to take out the cluster in order to access the board of the cluster. The operation in total took about 30mn.
    Again, the chip(EEPROM) was overwritten. This is often thought to be impossible. Oh well, obviously it is.
    There you go, my cluster with the correct mileage of my car now (105k miles). The M5 cluster when installed had 141.700 miles recorded in it.



    4.1 ADJUST THE IKE CHECKSUM AND LCM MILEAGE

    Now you have 2 problems. The checksum of the mileage stored in the IKE is throwing an error because the mileage was changed (It seems to be checking with the LCM module too).
    The LCM module at this stage will have the mileage of this original M5 cluster before it was corrected. The sync up took place when you did sync the cluster to your car in point 3.2

    Here are the errors.



    In order to fix the second error "Data filling difference to central light module..." you need to enter the mileage you have now on your cluster.

    Go to Units > LCM > Reprogramming > Write odometer






    Now that the mileage has been corrected in the LCM module and after you cleared the codes, you will see this error will come up again.



    Go to "Reprogramming" > ... TO BE COMPLETED

    5. SHOW THE GEARS ON THE CLUSTER


    Let's show the gear indicator on the cluster (Steptronic for sure, not sure if manual car do show here normally?).
    In order to do that we need to do some IKE coding.
    Pretty easy.
    Go back to BMW Scanner > Units > IKE as shown below



    The click Coding data > Write coding data as show below



    You will then be presented with the following interface



    Tick the box on the top left called "Gear indicator via CAN"
    Take this opportunity to select the appropriate gearbox you have. For instance here "Steptronic" means "Steptronic 5 speed". But for some reasons it shows as 4 speeds in INPA. Am I wrong here?
    Select also the proper engine you have, 4, 6, 8 cylinders...

    Once you are done (DO NOT TICK BOXES YOU HAVE NO IDEA ABOUT), hit the Write button, it will take a good few seconds then your cluster will reboot (Yes really like a PC)

    Ok so now the cluster will show your gears with the Steptronic/Auto gearboxes (Do they show on manuals?)
    See the difference?



    WORK IN PROGRESS I WILL UPDATE THIS THREAD AS I PROGRESS...THANKS

    BMWPlanetdude - I could kiss you lad. I really could. This is the most information I have ever seen posted about the M5 Cluster Upgrade. Brilliant! Thank you very much.

    I have some questions:

    1/. Does the Oil Temperature Sensor / Dial work now?

    2/. Do you know if this same process will work on an E38 (740i). They have the same M62TU engine as the E39.

    Thanks again mate!

    Just a quick correction: It's TAMPER dot, not 'temper'.

    Other than that, great deal of information pal! Usually this mod is done by guys that for some reason keep the secret to themselves. Bunch of a-holes.

    Thanks guys, yes it is long overdue and people in the know never published a DIY. Money is involved, but coding a M5 cluster is NOT something you will make a living on...anyways.

    I will publish other info and pictures in the next few hours once I am back home.

    You can actually adjust your miles for that menu on the IKE you have shown. If you see where it says "Write Odometer" click on that and enter your milleage in KM then save. No need for soldering and doing anything with other modules.
    As far as the oil temp gauge, I really don't know of anyone that's gotten that to work.

    No you cant if the cluster has a 35080 chip, I would have saved myself 70 euro otherwise.
    BMW Scanner is unable to write over mileage when a 35080 chip is on the way.
    You can on older models though.

    Yes the oil gauge can work, it has been proven already.
    Stay tuned.

    I have a slight uneasy feeling about showing reprogramming of the IKE & LCM.

    Pretty much all the people that want to mess with mileage with "evil" purposes already know how to do it. I understand your point, but in reality anyone with the slightest knowledge of how go Google can find instructions. This is part of a very good DIY that can't be omitted.

    Work in progress my friend, it takes time to figure those things out. There is no DIY out there remember?
    Stay tuned.

    Interesting thread mate. I long knew this was possible despite all the doubters that pop up on here whenever its mentioned! I've retrofitted high OBC in my E39 using a used cluster in much the same way, the only thing I wasn't sure about was the rev counter lights and the oil temp. There is a temp and pressure sensor next to each other on my 528, so its must be possible.......

    I love a good retrofit thread.....
