This is it!
The proper activator for Audi MHS2 systems made by delphi.
It a result of deep system analysis and some good reverse engineering.
The time has come and i have decided to share it!
Now is available free of charge for everyone!

Unlike the leaked version of the activator this one is tested and in use for quite long time now.
You will not loose ability to install custom POI's and for sure it will not cripple your legal function enabling codes.
I cannot guarantee that will work on every MMI out there, but i never had issues ever since i created it back in 2016.
Regardless of what some might say, update of the MMI is not mandatory. This is entirely up to you.
If your MMI is working properly and you have not noticed issues then you can continue using same version.
Believe me, i know these systems inside out.
As you will see bellow the supported versions list is quite long and will only get longer with time!
In case that you do decide to update then subscribe to this topic as i will update it to include software update info and files.

In the archive you will find a manual how to use it.
It is very simple process and you will only need one empty SD card size 8-32GB FAT32 formatted.
After activating the MMI you will be able to use latest navigation maps.

Here is list of supported versions, it was tested on many more but for now i decided to include the following.
If your software is not the support list then send the backup that the activator will make and i will add it. Always make sure you are using the latest version of the activator.
Almost any version out there!
If for some reason you cant get it to work following the manual then its likely that your unit was already patched.
In such case contact me and i will see what i can do about it.

Please have in mind that im doing this in my free time and that means that im not 24/7 available :)

The map of MHS2/MST2(soon to be released) is not installed, you copy map on SD and just insert in the unit. If coding is ok and fecs are shown as valid then map will work.
Simple as that :)

MAP 2022/2023 -> 11.64 GB file on MEGA
MHS2_ER_AU_K0129 -> 2.09 GB file on MEGA
MHS2_ER_AU_K0471 -> 2.53 GB file on MEGA
MHS2_ER_AU_P1242 -> 2.55 GB file on MEGA
MHS2_ER_AU_P2035 -> 2.54 GB file on MEGA

MHS2_US_AU_K0471 -> 1.02 GB file on MEGA
MHS2_US_AU_P1242 -> 1.01 GB file on MEGA
MHS2_US_AU_P2037 -> 1.02 GB file on MEGA
Software update instruction -> 720.9 KB file on MEGA
After using the activator unit will accept modified meta.
What you need to do is take the meta from 1242, remove any SupportedTrains or BlockedTrains and then replace MetafileChecksum with skipMetaChecksum.

For for example with the meta from 1242:
Remove those two lines
BlockedTrains = "MHS2_EU_AU_P01*,MHS2_EU_AU_K01*"
MetafileChecksum = "cd15b1487917b24e0ca50e0716bfa3d6dd7d710d"

And add these two:
EnableUserDefinedSWDLMode = "true"
skipMetaChecksum = "true"

Then make sure all components are select, the bare minimum is - MCM,78K0R,AP_ZR_HIGH1,TNRREF. Nice to select SpeechRes,SpeechAppRes.

Keep in mind that if something goes wrong you might not be able to fix it yourself and might need to send it to me.

Hi everyone, new owner of Audi A5 Sportback 2018 here. Looks like my car did not have Navigation in the package since it displayed "Navigation system not activated" or something like that. So i searched through internet and found this forum with Congo activator and latest maps. I successfully patched my unit, but when i copied the map data on the SDcard, loading stops @24% with the message "the navigation data is invalid". Do i need to have an original SD card? I used a plain Verbatim 32GB SDcard.... Thank you
All you need is a 32GB FAT32 SD card, unzip the contents onto the blank SD card and insert it into the mmi's SD1 slot.

1. maybe the download was corrupted, so do it again, or you used a mac pc for it, that also causes problems, only use windows pc for it
2. Do not use Micro SD card with adapter
3. which current software is running in mmi MHS2_xx_xx_Xxxxx
4. what says the log.txt file on congo activator you have used
Hi Alex, thank you for a reply.
1. Already tried that, used windows PC, same result
2. Don't have full size SD card currently, could it really be an issue?
3 and 4. This is a log file:

Activator for Audi-MIB Scale made by Congo
SW rev: 1073
Device type: MHS2
Brand: AU
Device region: EU/ER
FW ver: MHS2_ER_AU_P2035
FW MU ver: 0235
HW: 050
FAZIT: GRO-63331.03.1809010146
VIN: WAU*****
Install location ffs - should be as safe as possible :)
SE: 1
Metainfo patch successful.
SWaP patch successful.
EL list created successfully.

So i assume the only solution would be to buy a full sized SD card and try again?

thats the way buy a good sd 32 gb or 64gb for the future, the maps are every year bigger, I use only Extreme 32 or 64GB View attachment 185372
Hi Alex, bought 64 GB full size Sandisk SD card ultra, extracted 2022/2023 maps on it, put it in the SD 1 slot, still the same result:
Rectangle Gas Font Gadget Automotive design

Any ideas what am i doing wrong?
Thank you

the map on sd card FAT32 (tool )or test if working exFAT will only work in sd1 slot if you installing the congo activator!!
otherwise the FEC that your actual unit has, will not allowed to use newer maps
FEC maps
02500028 > 2021
0250002a > 2021/2022
0250002c > 2022
0250002e > 2022/2023
02500030 > 2023
02500032 > 2023/2024
Thank you for the reply.
These are the codes in my unit currently:
Font Gas Display device Electronic device Auto part

Does it mean i have to activate maps? My unit didn't come with navigation activated.

sd card slow FAT32 formated needs or then maybe downloaded file corrupted or Mac PC used?
its working with other/before used sd card with maps?
I have exactley the same problem, think i tried everything sugessted on this forum, always the same result... I've read on some other forum someone had this problem, turned out he had GPS deactivated on 5F coding. No specifics though how he re-enabled, but when he did it, navigation started working again. Anyone have idea how to re-enable GPS?
