Hi to all, Im new to OBD11 forums. Was wondering whether I can get some assistance as I have a complex issue with my infotainment system and need to get to the bottom of it. I have a MK7 R MY15 with a retrofitted VW genuine Discover Pro MIB2.5 infotainment system that was retrofitted by the previous owner. History goes that owner purchased the unit from VW Central in Syd, AU already pre-coded to work with installed firmware (1155 I believe) and system was working OK when I used it. However, given that VW had released the latest and final update to these units (1367), I wanted to update the unit to the latest version. But having not done my homework beforehand, I didnt realise that updating firmware required a re-code and reset to the unit in order to make it work with the newer firmware. The update 1367 completed successfully but I can no longer use it as it restarts every minute or two and screen goes blank. I did a scan of control units with my OBDeleven tool (have the Pro subscription) which also brought up a bunch of Component Protection errors ( U110100) in MULTIMEDIA 5F and GATEWAY 19 control units. Tried clearing them using OBDeleven but nothing worked. I have attached below the details of the scan. Ive been advised that to get these removed and make the unit work again, I need to take it to a euro specialist so they can reset and recode the unit to work with the newer firmware. But Id rather do it myself if there is a way. Hoping someone/anyone, maybe DV52, has the answer  Reading the forums, he seems like the go-to man around here and I'm also in Melbourne, AU. I'm hoping you can help me out here as I need to get issue fixed. Thank you.      |

@v1r : Hi. hmm......... i'm guessing of course - but based solely on the information provided, my suspicion is that what you actually have in the car is a retrofitted MIB unit which was hacked by the equipment seller. The reason for my hypothesis is two-fold: - You say that the new MIB was " already pre-coded to work with installed firmware". At least officially, it's not possible to install a new MIB into a mk7/7.5 by just plugging-in the module; after the fitment, the entire car needs to be connected to VW's remote servers (called FAZIT) and a process implemented to re-authorize the new MIB into the car's VIN and to transfer the licenses (called FECs) from the old MIB into the new MIB,. When this process is successfully completed, the Component Protection (CP) errors can be deleted
- Your car has CP errors active both in the new MIB and in the Gateway module - which is the CP master module. This is a classic indication that the formal VW process for deleting CP errors has not been undertaken. I suspect that these CP errors were active before the firmware upgrade. If I'm correct, the fact that the MIB worked before the firmware update strongly infers that the new unit must have been hacked.
So, here's the thing- when a MIB is hacked to by-pass CP, VW's standard firmware in the module is necessarily broken because software needs to be changed to implement the hack. The actually changes that are made can be different for each hacker. This means that it's anyone's guess how a module firmware re-write/update will affect a hacked module. My suspicion is that the new SW in the module may have overwritten all, or some-of the hack, so the CP errors (which have always been there in your car) have now become binding. Hence your observations - but again, I'm guessing
Your could try the easy stuff like perform an XOR calculation on the "software Version management" error (see HERE) and then re-set the MIB unit - but I suspect a trip to a dealer might be required (if a dealer will agree to play with a hacked MIB). Or, I guess you could contact VW Central and ask if they can fix the problem (either remotely, or by sending the MIB to Sydney)
Also, I note that the software switches on the long-code string for the new MIB have DAB radio activated - but your scan has an error showing that the digital radio antenna is open-circiut. The suggests (to me, at least) that your car may not have had DAB radio factory fitted and therefore the car may not actually have a DAB aerial! If I'm correct, maybe consider resetting Byte 10 from hex11 to hex00.

Hi Don, Appreciate your reply, i wanted some with your kind of knowledge to better explain the MIB2.5 issues . Im really pissed at the original owner due to all the issues im now facing. Not only did he disable the seatbelt reminder (ive fixed that), he also physically disconnected the structure borne sound (lol, why would you do that when you can disable it). See my responses below:
Point 3: Thanks for providing me with an overview of what transpires, now I better understand what is going on. Your guess seems about right.
Point 4: the first bit I've already done, i followed the instructions in the other thread for Software Version Management fault, so Ive cleared that fault. I used an XOR calc to do it. But all the other stuff is still there and i suspect thats only part of the solution. Btw, when you subsequently say 'reset the MIB unit' is that just a soft/hard reset using the menu items (factory reset) and/or hold power button for 15 seconds.
As for sending the unit away, im trying to avoid that as much as possible, given time and expense. VW Central referred me on to a contact of theirs, but Im guessing it will be the same deal, I still need to send the unit to Sydney and that requires me to disassemble the entire unit from my car, which Im not really keen on doing. I also have a contact here in Coburg (CVE electronics) who said they can provide a fix for around $500, but they need the car for at least one day, maybe two. Option 2, taking to dealer, dont know, they may want to steer clear of hacked units, period.
Point 5: I believe you are correct, going off what another contact also explained to me. I'll just change the HEX code, which I'm assuming will allow me to permanently remove the error. PS: another thing, my START STOP, was working perfectly but I hate the feature so I used OBD11 to disable it which worked. Now for some reason, I cant re-enable it. I believe Ive configured everything properly but on the instrument panel next to digital speedo theres a '/' thru the SS feature. . Looking at my menus, i can see the reason for it, 'operating power too high' or something like that. But why did it work before i changed it. Setting is on 7.6 atm. I would like to know your thoughts. |

Your link says : Package Contents - Genuine VW MIB 2.5 Discover Pro Infotainment Radio Control Module (Fully Unlocked)
As is their normal practice - VW Central is being a tad devious IMO by using the words "fully unlocked". In truth, this is code for what VW Central really does to their so-called "genuine MIBs"; the module software is hacked to allow the MIB to operate (after fitment) while CP errors are active in the car.

I would like to know your thoughts. I'm not sure why you can't restore SS - but there are a number of ways to delete the function. Are you certain that you used the "voltage method" originally? Also. there are lots of reasons why SS might not work when the function is activated - like engine temperature, Air-Con setting etc - could these other factors be the reason? |

Can I just add a couple of things? (Not wanting to step on dons toes here)
SVM is only a error for dealers to tell if they have updated the software (like the security update), it doesn’t do anything, I had a word with a VW tech mate and he explained that and that’s why Vw don’t delete it
If you have a mib2.5 then you can use a sd card to clear the CP and add FEC codes but as I’ve not done this myself I won’t go in to it (google is your friend here, plus you may have a problem getting into the unit if it’s switching on and off tho

No i didnt use the voltage method originally, I believe I used the 'deactivation of start/stop function' parameter, but cant be certain. But you know when you do something and forget what you did days later, thats my case now  Whats the other way to disable it. |

After that, screen goes blank and system normally reboots. Can buy an SD card, no issue, but I wanted to know how to do it before I play around with anything. Ill check on Google, do you have a specific URL you already know, that you can point me to. |

Not much point guessing what change was made - best way is to examine the records in your History report - find the tweak details and revert to "old value" Don

Hmm, the below vehicle history image, it appears that the start-stop function wasn't done via adaptation or long coding, but rather via the 'app'.  |

update: just sorted everything out and made necessary changes. SS is now fully operational.
Just wondering from VWJap if he/she has a preferred link I use instructions for the MIB CP/FEC codes. I tried searching but didnt really get anywhere.

Maybe search for Vw M.I.B tool
not toolbox that’s just for making your screen pretty
Most info is on telegram, but I don’t know how to post a link (plus I really don’t wanna put it here)

Okies, thanks vwjap.
With telegram, isnt that the cross platform secure messenger platform. I must say I havent used it, i normally use the signal app.
How do I get info from there, though. Can i somehow add you to the list of contacts so you can provide me the links on telegram.

Hi DV52, just wondering. I have managed to re-update my MIB2.5 correctly and installed MIB toolbox, but need to clear an SVM error after MIB toolbox install. Ive followed instructions on another thread but for some reason, my Confirmation Installation Change value = 0. When i input that into the website XORY, comes up with an adjusted HEX of 5f. But my obdeleven wont allow me to change the code under Adaptation. Says function not available. Any ideas.

Hacked units sometimes do that, depends what hack they used, it’s part of the hack
Toolbox or mib tool?
Sure mib tool has a SVM clear on it (just checked it does)
