My Q6 Quattro has lost its onboard internet connection, this has the following consequences:

Together with the dealer we performed a MMI Factory Reset and now the MMI doesn't switch back on anymore

I left my Q6 e-tron quattro at the dealer yesterday.

additional info: I am pretty sure it lost its connection when I crossed the border from Italy to France last Friday, until that moment everything was working fine (I drove ~1000km in Italy before this trip to France). Once in France I noticed the navi was not showing traffic jams anymore, and we ended up in a pretty big jam. At the time I though that maybe I should have enabled roaming somewhere. Later I also noticed I could not check upon my car from the myAudi App.

Back in Italy the problem persisted. And I started investigating a bit more. On the MMT screen the connection icon (usually showing 5G signal) was indicating 2G, in the Navi screen on the bottom left I would see a cloud icon with a diagonal stripe through it and the text offline next to it.

Thta is when I decided to visit the dealer and leave the car. I suggested a reset of the communication module since it was all due to the MMI being offline.

UPDATE: I just received a call from the dealer, the issue has been resolved by resetting the OCU (I guess it stands for Onboard Connection Unit ;)) by removing and reinserting some fuses. The bigger issue should be resvolved in the next software update. Will pick up the car after lunch and see... Ow and I will ask which fuses to remove to reset myself in case I might need it again.

@bwa unfortunately I have no photos of the MMI at that time. Will do next time, although I hope it won't happen again

Update: picked the car up tonight. And after spending half an hour setting up everything I had set up in the past two weeks I was ready to leave.

They didn't want to explain me which fuses I had to pull to reset the OCU so I hope it doesn't happen again.
