Hi folks, i own a 2009 4x4 2.0 tdci kuga which now has a damaged (non repairable) rear diff control unit. I've priced the part of ford but the car isn't worth spending £800+. So im currently trying to get one off a car dismantler. my questions are, which number on the sticker has to be the same if not all of them? And if i buy a second hand one is it plug and play or does it need programmed? Any help is greatly appreciated. Photo of part sticker attached.
