I feel you! I've definitely had my share of headaches with Audi customer service too. It’s such a drag when the reps aren’t helpful or even just nice - it just makes everything way more frustrating. Fingers crossed they get their act together!
I had the same thing happen with my e-tron a few months ago. Out of the blue, this warning popped up. I just gave it a quick reboot, and it’s been smooth sailing ever since! No more issues, thank goodness!
