Just picked up the brand new Q6 Etron first edition and it has the same issues and others,
Does not save radios.
Keeps asking you to accept privacy statement to use Audi Connect.
Front and Rear UTR cameras will not connect to app.
So Audi's brand new designed from ground up Q6 has issues with the MMI and this car is 4 days old.
So you are not alone with the A3 or S3 range.
Problem has not gone by October 2024.
