    Component Protection Removal Through VCP?

    Guest-only advertisement. Register or Log In now!
    I saw this as one of the last comments on the 3G+ MMI thread:

    "You can copy the component protection from your old unit to the new unit using a VCP(Vag Can Pro) cable and software. It allows you to read/write to the eeprom. If you are technical minded it is fairly straight forward. No need to visit dealer and you can freely swap between either unit if needed as the component protection will be identical on both the old(3G) and new(3G+) devices."

    Is this real? If so, what cable and what are the steps?? We could all do this and not have to go to the dealer for anything!!

    From what I remember from my MK4 days you could do something similar with gauge cluster swaps to avoid having to adapt the immobilizer to the car.

    Pulling the eeprom file off the cluster and loading it back on was pretty straightforward with the right cable/software. Modifying the file wasn't intuitive at all.

    I had a stubborn cluster that the previous owner had "reset" improperly which goofed the software in the cluster and didn't allow it to adapt to the car. After taking the eeprom file from my original cluster and finding an unmolested file for the new cluster someone was able to put to two together and send me a modified file to load onto the new cluster.

    Where did that quote come from? With the right cable it's feasible that we could pull the eeprom file from both MMI units and have someone create a new file with the component protection info from the old unit. The average forum user isn't going to be able to modify the file.

    Edit: Here is some more nerdy stuff. http://audienthusiasts.com/Infotainment_EEPROM.html

    It looks like it might actually be as simple as retrieving the eeprom file from both units and copy/pasting the component protection section from the old to the new using a hex editor.

    I saw some guy on a forum in Europe that apparently can do it remotely. You connect with vag com or something and he uses some software to do it. Seemed a little fishy, so I just paid the 130 at the dealer and it was done in less than an hour.

    With the right know how and software it's probably possible, but for most of us not really feasible.

    Nothing fishy Scott:), but those guys removing cp online(like dealer), not "eeprom" play like on Davids site. As far i remember OP had concert or symphony, so vcp will not help him!

    I hit him up and he wanted more than the dealer to do it so I passed. If someone knew more about this and had experience I would love to complete my 3G+ MMI swap on my own. I hate anyone touching my car for anything

    It can be done using a VCP cable, you can copy the old CP from the headunit and squirt it into the new one - 3G > 3G+, not 2G to 3G.

    HOWTO: Copy component protection from one MMI unit to another using VCP Cable

    Ok, since this seems to be getting requested quite often now, rather than replying to a bunch of PM's I am going to write up a quick howto.

    This is assuming you are doing the MMI3G to MMI3G+ upgrade, but should also work if you needed to replace an MMI unit for some reason.

    DISCLAIMER: I am not responsible if you brick your MMI or your whole car. If you aren't comfortable with the procedure, just go to the dealer and pay for an hour of labour.

    1. Obtain the parts needed to do the swap, you will need the MMI unit and Control Panel. Do your research, make sure you get what you need to fit your car. Optional: fakra antenna cable for GSM connection. Keep your old unit installed until you read the EEPROM.

    2. Order a VCP cable. I used a knockoff, it worked for this procedure. Really cheap here at the moment -> https://www.obd2cartool.com/vag-can-...scanner-p-1159

    3. Install VCP software on your laptop, make sure it is working. Connect to OBD port in your car. You want to connect to module 5F for this. On main screen under ECU's click the "more..." button. On the next screen click the "Infotainment" tab. Finally, click the "[5F] MMI 3G" button. See screenshots.





    4. In the next window click "CONNECT" to connect to the module. Once successfully connected under "Advanced Functions" click the "FLASHER" button. Note: It may have a different name depending on version of software. See screenshot.



    5. You should now see a window like below. Screenshot is a little low quality but all I could find as I no longer have my car to connect to. There won't be any data in it until you read it. This is just to show you what the layout looks like.



    6. In that window you are going to want to fill out the following fields(just under the toolbar working from the left) as follows:

    Login: 21055 or 20103(can't remember which one I ended up using, if one doesn't work try the other) click the key icon, you should see "login ok" down at the bottom in the status bar.
    Address: 4096
    Length: 8192

    In the pulldown at the end of the row, choose "engineer mode"

    7. Once you have those fields filled out click the little button that looks like a "play" button, you should should data start to fill up. Once it finishes, make sure you save the file for future use as this is where you will get your component protection data.

    8. Here's a youtube video I found which shows the procedure on a different module but should give you a better visual -> https://www.youtube.com/watch?v=dyok8kqoh-U

    9. Double check to make sure you have file saved in a safe place on your hard drive. Maybe make a backup as well. Can't hurt and will save you from swapping parts more than once.

    10. Remove your old MMI unit and control panel. Install new parts. Before you remove your old stuff I HIGHLY recommend taking screenshots of all the options in the green menu so you can reproduce your setup on the new MMI. There's a lot in there.

    11. Repeat steps 3-9, making sure you use a different name for the eeprom dump, also make sure you know which is which. :-)

    12. Download a hex editor of your choice. Any one will work. Here is a free one -> https://mh-nexus.de/en/hxd/

    13. Open the file you saved from your original old MMI unit in the hex editor. You should see something like below.



    14. Scroll down to offset 00000640. Highlight from there until the end of the line at 00000770(basically 0000077F is the end.) It's easy to see as there is no data before or after. Right-click and select copy. You can paste it into a new file and save that somewhere if you want. That way you will have the component protection saved somewhere on it's own. See screenshot to see what you should be highlighting.



    15. Close the original file. Open the file you saved from the new unit. Highlight the same section as you did above, right click and select paste insert or paste write(assuming you are using HxD). Make sure it overwrote the data and didn't insert it. It should warn you if you did it wrong saying the file size will be changed, you don't want to see that error.

    16. If you have successfully copied in the date, save the file preferably under a new name so you can compare the original dump with the edit and make sure only the component protection portion has changed. WARNING: Double, triple check, whatever you are comfortable with. If you write the wrong data back to the eeprom you could brick the unit.

    17. You are now ready to write the file back to the eeprom in the car. Repeat steps 3-9 but in step 7, click the open button and select the new file you just made above. Then instead of clicking the "Play" button click the RED button next to it.

    18. It should start writing the data to the eeprom if you did everything correctly.

    19. Once finished reboot the MMI using the three finger salute. Once it reboots, everything should work normally but with a nice new updated user interface.

    20. Crack a beer and enjoy some tunes on your new MMI, preferably streamed over bluetooth as you should now be able to do that. If you feel like sending me a beer so I can enjoy one with ya -> tip jar

    I hope this helps everyone out. It took me a while to figure this all out back when I did it and it was a little nerve wracking doing it but was super pumped when it all worked out.

    PM me if you have any questions or you notice some errors. This took a while to write up and I am sure I made some typo's etc and my brain hurts now. :-)

    I'll probably have to un-CP these new modules:

    In Terms of Component Protection Hex Dump, Will the Protection Section always be between 00000640 and 00000770. I wanted to upgrade my subwoofer to a newer version. Would this Method apply to all Components? I Have Concert 3G Model AMI.

    Hi. What is the issue If «Flasher» is greyed out? I am not managing to find the correct access code SN: 189j60c7524654 HW: 4g0035666H

    None of these work: VIM Code 1: 05244 VIM Code 2: 02464

    UPDATE: Figured it out. Had to go to up/download.

    But 1 question remains.

    Does the CP always start at 640? I have several lines starting from 580 and all the way down to 770.

    Wow, thanks for such a detailed run down. I will be sure to send a little something your way........Do you happen to know the lines to copy paste for the Climate Control unit CP?
