Good afternoon colleagues,

In my A4 B9 from 2016 I had the firmware MHS2_EU_AU_P0114 MU:0102 installed and overnight, because yes, the USB has stopped playing music with the pen that I have always had, it was not detected by the MMI, however, by cable the android auto worked perfectly

Searching, I have decided to update the firmware to MHS2_EU_AU_K0137 MU: 0243 and everything has gone well, but once installed now I can not enter the car settings when entering, it tells me that the services are not available

"the settings for the vehicle systems are not available"

Could it be that I do not start because of what I have previously activated with obdeleven?

Have you tried to patch the system with the activator?

Hi,
I just installed the patch, I got a green screen, it rebooted and I haven't done anything else. I went into the red update menu based on the .PDF file but it doesn't give me the option to install anything. I still can't get into the car configuration, I don't know what else I can do.
 
Hello again, I fixed the error. 4:30h coding the entire 5f module based on a backup that I made when I bought the car with obdeleven. I don't know why, but all the values were deactivated and at 0. With the backup I left the serial values.
Glad to hear that you’ve managed to fix it! Maybe the values got deleted while saving the changes you’ve made.

Thank you very much!!
I can sleep peacefully now :)

I don't really know why the configuration was not correct, but I updated the MMI firmware because the USB stopped playing music and now when I coded the whole module from scratch, line by line and code by code, I saw that this option exists and it was disabled and when I activated it it started working again.
I don't know why it was disabled, nobody touched it...
If anyone needs the backup, please ask me. It might help people with the same car as me

Thanks again
 
Hi there, could you please share what codes you have changed on VCDS?
Hi guven,

the changes described by alex:
Go to the Module : 5F. (Information Control Unit)
go to Adaptation -> Vehicle Configuration
Enable Apple_DIO and Google_GAL



And the last change go to byte19 and set the value of the bit 6-7 to *usb_ipod

The changes are also described in the activate instructions pdf on page 7.

Best regards,
Edi
 
Dear all, I have already applied congo activator and my navi can handle latest maps.

So if I buy this cable, and then remove my unit (MHS2-MIB2)(without removing glovebox compartment), attach yellow tip to back of my unit, attach black and red cables to green connector accordingly in this video, finally connect green tip to usb out (part code 5Q0035726E). Will I have carplay once I update coding via OBD11 as below?

[*][*]Module : 5F. (Information Control Unit)
Adaptation
Vehicle Configuration
google_android_auto (on)
apple_car_play (on)
Apple_DIO = On
[*]byte19 usb, has to be ipod (not full)
If you have the charger with the two USB slots under your arm rest, after installing the patch and performing the changes with obdeleven, you should be able to use apple carplay via your already build in USB Data slot (Not charge only).

If you have only the charge only slot then:
You also need this Adapter (OEM 5Q0035726E). The adapter is capable of not only charging but transmiting data. And the adapter itself has some build-in license or some sort of.
This adapter can be placed in your glovebox. By using an wireless adapter (like the carlink 5 2Air) you can configure it to work via bluetooth and wi

Or you could buy this set and replace the whole unit under the armrest: Original Audi Smartphone Interface Nachrüstung USB MMI-Display Sprachbedienung 8W0051472

PS: I am stil waiting for the small adapter to arrivr. I’ll update my comments as soon as I tested it out.

Best regards
Edi
 
just install the CONGO ACTIVATOR, then if hardware missing see here the video how to do

you need the cable(because of data connection/connector) today your usb are only charging! and
you need this 1x usb interface because inside they have the chip for data (license) inside!
costs:
Update:
The package with the hardware arrived today and I already managed to install it. Everything works as wished:

the usb slot I managed to install in the glovebox, in a pocket that I never used. I attached both, the usb device and the carlink adapter with velcro to the upper wall.

it‘s important to install the cables in such a way, that they‘re not vibrating during the drive.

voilà:

Anyone knows how to clear SWDL History in a MHS2 unit? I know the error I have in obd (B200087 Software incompatible) is due the downgrade I did, but probably there's a log file somewhere that I should be able to clean and keep only the firmware version I have now. I can connect through telnet, but I don't know which file should I look for.
