So my passenger seat has become a bit wobbly and i found today that a piece of black plastic that the seat runs on is to blame, as you can see from the photo its broken in half! It goes here; And here it is, still intact, on the other side of the same seat; Has anyone else replaced one of these? Im having a trouble getting the seat out, i have disconnected the battery and removed the 4 6mm allen bolts in the runners but the seat doesnt want to come out. Im assuming i have to first remove the seat itself and then the subframe after??? I have the A3 interior workshop manual but it seems the set up is different on the s3? Thanks.
