CAPS user name is no longer needed. But if you get a Connection Error after a long Please Wait then check that your eSIM module is OK. Mine was stuck in Service Mode and needed to be unstuck to start working.

Just remember that to start it up, you need to go to the Telephone menu.

Ok, to avoid further irritation here's what I did to get it working:

Symptom: you got your brand spanking new Audi with MMI (in my case an SQ5), and in order to activate functionality like remote status report, remote locking, etc, you have to become the key user. However even after doing all the paperwork, the friggin' MMI menu does NOT show you a 'Key User' field. Instead you just get this lousy 'no users - refresh list of users' message.

So, here's what worked:

1) Menu -> Audi connect -> Options -> Log out (!)
2) Switch the car off and make sure the nav system actually shuts down. Your display might go into sleep mode. Want to speed this up? step out & lock your car.
3) Get back in, start ignition (not engine), go back to 'Menu -> Audi connect -> Options -> Audi connect user management'

Marvel at the beauty that is "Key user - add key user". At this point you think: Success! However, more to come:

4) As the username use your myAudi account email address that was used with the dealer activation paperwork. IN ALL CAPS. Everything. Even the ".com " or whatever you have. All in caps! Even if your registration email shows lower case.
5) Then use that silly 10 digit code (hidden behind a scratch-off surface) as the password

Now you're golden. It'll tell you that you are now the key user.

Go back to the MyAudi portal, log back in or refresh the page that has the connect services widgets, and you'll now be able to remotely set geofencing, see a report of the car, see status of doors, etc.

In the mean time, if Audi AG is reading, PLEASE update your damn documentation to show what happens if the menu isn't exactly what it shows in your PDFs. (e.g. this one is broken as it misses the whole point of becoming a key user when you are in a half activated audi connect situation: https://www.audiusa.com/content/dam/...etup-Guide.pdf )

Lastly: if you get a 'Great there is NO myAudi account registered' then you have a) successfully typed in the 10 digit code, but b) typo'd your email address.

Security through obscurity. Please next time just have the email give us an image that we show one of the myriad cameras of the car. See "Whatsapp Web" for a MUCH easier way to solve for this problem.
