i have a 2015 A8. Initially it was annoying me that ever time I backup the screen would pop up and the backup came would come on. I used my vag com and did a mod that I thought would make it so the screen comes up when I reverse only if I manually put the screen up. What I got was the screen still comes up when I put it in reverse but I disabled the backup camera. There is a option in the MMI to choose backup camera or a diagram of a car. This does not change anything if I change the setting. I need to reverse the change I made with the the vag com but I can't find the instructions I used to make the initial change. Thanks for reading. John
