Last few weeks I have been getting a warning on the radio saying "Unknown Driver.....delete primary user" when I first start my car. After a few seconds it goes away. I have a 2021 GTI S DSG and have taken it to the dealer and for some reason they can not figure it out. Wondering if anyone has had to deal with this problem and how did they fix it. I have disconnected the battery, reset the radio, searched the menu....nothing.
