Yes I have a similar, though not exactly the same, issue asking me to complete setup by contacting my audi partner to set me up as owner of the vehicle, see attached screenshot. Audi Digital services just telling me to do the "normal" troubleshooting things, such as resetting password etc, which never work!
Yep, I got the same error.
Noticed it on my iPhone last Friday evening (15th October). Device and app up to date. This screen also displayed a 'vehicle status could not be retrieved' box and the vehicle status would not update.
Contacted Audi Digital Services, who had me (a) log out of myAudi (b) change region and login (c) change region back to UK (d) reset password and anything else they could think of....all without it making a blind bit of difference. The email I was then sent with the case reference asked me for my inside leg measurement, blood group and a screenshot.
By Saturday morning (16th), the app had stabilised and was updating status (mileage, fuel tank %age, location, warnings - the washer fluid needed topping up). Thought no more of it until Monday this week when a new message appeared over the centre of the home screen - "The Audi connect infotainment services are not yet linked to the vehicle. Please enter your myAudi email address on the vehicle MMI."
The app was still syncing in real time at this stage.
Conatcted ADS with an updated screenshot and the response was:
"After checking your vehicle into our system, we can confirm that you need to perform the MMI login in order to be able to use the navigation and infotainment services in your vehicle.
Please follow the steps below in order to log into your vehicle's MMI:
1. Switch on the ignition and access the main menu of your MMI
2. Select Users
3. Click on Add User
4. Choose Log In now and insert your myAudi account credentials (email and password)
After that the 'link vehicle' message will disappear from your myAudi app."
Have yet to try this, but assume that because my password was changed this is the reason. I'll advise an update when I've tried this, but it is interesting to see that other subs have similar issues when the ADS mantra is "it must be at your end, guv."
The app is no longer syncing.
