They replaced the whole panel on mine. Not sure what the cost was as it was under warranty. Word of advice though, if thats the only problem youre having with the mks, count yourself lucky. I just got mine back after the dealer having it for 8 weeks to repair what they thought was the cam phasers only to find out the timing chain and tensioner were shot. Kinda ridiculous since it only has 63k on the clock. Before that they had it for 6 weeks replacing a stuck open injector along with the whole exhaust system since the cats broke apart from the heat of all the fuel burning off in them and stopped both mufflers up. Ill be sending this one down the road very soon and will more than likely not be looking at another Ford product again. Between this one and my truck, Im done......
P.S. Sorry for the rant but I do feel a little better now.
