Have you turned it off and on ?
pull fuse of MMI or disconnect battery. Unit got stuck in reboot. reset is not working here.
Yes, I tried to turn it off and on but no change.
Also pulled fuse and disconnected the battery. Still not working. Does it mean that I bricked my unit? I connected the obd11 and it doesn't show the 5F control unit at all. There is error code on engine control unit as well which is DTC U105400 (Information electronics control module 1 No Communication). I'm not able erase this as well. Hopefully there is a way out for me. Please suggest and help. Thanks in advance.
I do not see anything in M.I.B LOG, that should lead to a brick. Patch was done one reboot earlier, so that has worked.
Did you leave some time between disconnecting and connecting power again? Like min. 30s? If you are too quick MMI will not power down fully.
Do you have D-LINK?
Next step would be to get UART equipment and check output on MMX RCC?
No, I don't think I gave the min. 30secs after pulling the fuse or disconnecting the battery. Let me give that a try again this evening and update you. Fuse is mentioned as infotainment and not MMI. It is a 5amps fuse. Is that the correct one? And the battery in the boot needs to be disconnected and not the terminals under the hood in the engine bay, right?
I don't have D-LINK. Nor heard about UART equipment. Will search for them on Google and get myself ready for it.
I'll keep you posted.
Thanks again for your timely support. Much appreciated.
Best regards. Rohan.
Sounds a bit like you might have missed the right fuse/battery. labeling of fuses is quite confusing. Also screen and MMI are most likely on different fuses.
Pull unit and disconnect quadlock
Ok. Let me check the manual thoroughly for the right fuses and re do it. So do I need to pull the fuse for both infotainment and scree if they are separate? Anyway I'll keep you posted. Thanks for the pointers.
MMI is important
Ok. Will look for MMI fuse. And what is pull unit and disconnect quadlock? Is this the SD, sim and DVD unit? If so can you direct me to the instruction video or link. Else I'll search the Google if you just confirm. Thanks again.
Quadlock is the connector on the back of the MMI. After you removed it from the car.
Hi @harman-f . I did pull all the fuses which had "infotainment" mentioned in the description in the manual and left it for a couple of hours and then put back all the fuses and turned the ignition on. Voila! The MMI came back to life and loaded everything successfully. I bet I missed the right fuse during the 1st attempt like you said. Thanks for your advice. Much appreciate your ever supporting and helpful nature. You are the best! I was very much stressed and was panicking thinking that I might have bricked the MMI. Anyway, all good now. Do I need to insert the SD card again and take a new back up in the MIB? (I'm a bit scared now to run the MIB tool 😬.) Or just leave it as is? I think I need to connect the obd11 and clear all faults for sure. Please let me know your suggestion and we can close this issue. Best regards, Rohan.
This can happen, but does happen rarely. Use M.I.B as you wish. In case you get stuck again, pull known fuses ^^
All done. Took the latest back up and everything is okay now. Thank you very much again @harman-f . Cheers!
Which fuse did you pull out?? Too many infotainment fuse there..

I tried to enable the dual navigation on my 2018 Audi Q5. To complete the process MIB restarts the MMI and it never restarted. The screen started to flicker and in VC "initializing" kept doing rounds. MMI shut off after like 1 minute. I tried MMI rest with left, right and center joystick button. It then started to repeat the same flickering and then stops and shows as "unknown" in the VC.
I tried removing the fuse and disconnecting the battery terminals. Didn't resolve the issue.
Background: I had just updated from stock firmware MHI2_US_AUG22_P3252 to MHI2_US_AUG22_K3347 and then patched to update to latest maps just yesterday. While patching it took MHI2_US_AUG22_K3345 automatically. Everything was working fine. The navigation map were the latest and no issues were there. I just wanted to enable the dual navigation and this happened.
Please please please please help. I am stressed out and panicking.

Looking forward to your support in resolving this issue. Thanks in advance.
