The seat part in other models is the minimum easy entry will affect and the steering wheel is usually an optional part of that since an electrically adjustable steering column is obviously required and that is usually optional. If on the A8 it is (and is only supposed to be) the steering wheel that moves as part of easy entry, then i’m pretty sure the seats can be coded to join the party. I would look into the seat modules coding because thats where you normally activate that. You can also usually turn on menu controls for the seat part there.
Again, i have not tried to do this on an A8, but i am pretty confident it can be done based on the fact that a lot of stuff is uniform.
