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.

Hello, can someone explain me how to activate the green menu on MHS2 (AUDI A4 B9) with VCDS , so i can update my license to lifetime the activator not working for me because i have only 1 usb (Charging port only)
hi,
if you have an sd 1 slot, then run the congo activator, it will work for lifetime navi-maps!
it takes 5 min. only,
what actual MHS2_ ... software are running?

Open with VCDS STG 5F
1. Access code: S12345
2. Go to Customization [10]
3. Select IDE02122 developer test mode ==> GEM(Green Eng. Menu)
4. Set it to active
5. Restart MMI UNIT → Press the ON/OFF button for 30 seconds
I think the cango activator will not work for my car because i have 1 usb port only charge, i think the cango activator is for two usb ports unit
my software is MHS2_ER_AU_P2035
it will work too!!!! what you are saying are not true!!!!!
has nothing to do with usb ports! usb port are only for carplay/Android Auto function!
Ok, thanks will try it :)

Hello, unfortunately not, but from the information I read on the Internet, you need to have a D Link DUB E100 revision D1, which is now very difficult to find, Odis or VCP and through the computer through the Puffy program, change the region from US to ER
I have the D link DUB E100, but did try it with the activator with different SD card and it successfully installed

Hello ! I want to try to update the navigator myself . Tell me , if I want to upgrade to ' MHS2_ER_AU_P2035 ' , it doesn't need 2 USB ports under the armrest , I only have one USB ? I understand that you just need to download the firmware (P2035) to the SD card , insert it into the first slot and update using the red menu . Then activate the activator (Congo Activator 2.5) . Do I understand correctly that I can update with one USB port and the two USB ports under the armrest are only for the carplay function ?
Thats correct your undestanding i right, today i learned that for the activator to work correctly the memory card should be SD card and not micro SD card
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: View attachment 185378 Any ideas what am i doing wrong? Thank you
