I just purchased a 2010 with just over 23k miles and love it. Just had a couple questions. I've read about earlier years having trouble getting their gas flap open, but on my 2010 it never locks. By looking at it, it seems it wasn't meant to lock. Is this normal for this year or is there some reason it isn't locking when the door are locked. Also trying to change my display from "miles to empty" to mpg or instant mpg. I have NO BUTTONS on the end or on the bottom of my wiper stick. I understand this switches it on those models equipped with the buttons, but anyone know how to change the display on the 2010 a4 with no buttons on the stick. thanks! any help is appreciated!!
