I am replacing a rusty drivers side door on an A4 Avant which has seat memory with an A4 door which does not. Can I just swap my original door panel over to the new door and all is good or does the mirror have anything to do with it? Also if I wanted to swap my driver seat (cracked leather and finicky motor) with a non memory A4 seat, is that possible or are there electronics to worry about in the seat?

Thanks
