We are so loving our new 2019 E-Tron! Our initial problem was using the provided charger and getting it to keep charging using our ordinary outlet in our garage...I thought we might have a "dud". First, since we currently had 55% capacity we had to set the intended battery level over that (to 80%) in the car, and to 100% on the home charger. I thought that was going to work, but no! We finally realized that the "convenience" key was unlocking the car, thus repeatedly terminating the charging function as we edged out of the garage. If you have a tight fitting parking space in your garage - leave your key outside!
