Hi all, now my 03 plate 172 has the button for ESP but when I press it I get nothing, no light on dash etc, I even span the wheels by pressing the button couple of times, when I take the panel out there is a block connector connected to the back of the button which indicates its suppose to be working but I don't no why it isn't, all I can think of is the bulb behind the dash for ESP has blown or a fuse, I'm not so sure on fuse as the button still is illumined when dark so surely a blown fuse I will have nothing or am I wrong?
