Hi, I'm a newbie here and my air suspension is currently inactive, but got me thinking, how do I know if I have all round air suspension or just at the rear, I'm driving a 53 place 3.0d Sport?

My self leveling suspension is inactive and come to think of it I transported slabs/bags of stones recently, which fuse number is it and which fuse box so I can check and rule the fuse out or perhaps its a simple as that, that would be a result.
