Hi
I have the same problem in my Audi A7 I got my car in the month of March at Audi in Malmo Sweden. They say that the fault lies in the gearbox, I've waited 6 months for Audi in Germany to repair the problem

Another problem I have on my car is when I brake so crack, the whole front carriage let mighty bad for a brand new car, I leave my A7 at the workshop, they have change the brake pads.
They got away large part of the sound but it is still a sound just before the car stops completely
does anyone have the same problem?
