HI,
Worthwhile trying, but didn't work for me.
I redeployed the app and changed the pwd & got as the reset - did a "soft-reset" .. meaning holding the volume control knob for ± 15 secs . When it comes up I see it verifying my original/current key user (lets say XXX) for access ... and then I get the user dialog. XXX is still listed alongside 'Guest' but I cannot apply its settings (tech error) .. I cannot delete XXX .. and I cannot add a new user with the new password: "technical errors" everywhere.
The only option I see is do a full factory reset (the nuclear option) .. but I understand I may need dealer approval with registering a new user 😞
So still stuck ...
This whole key user thing has always been unstable; I had issues with my last Audi too and had to leave it at the dealer.
In any case, if anyone has any suggestions/advice it would be welcome
