Hi. I am after some help and advice on upgrading to a MFSW... Off my build sticker i have found the code - 1MR = Leather steering wheel At the moment i have this style of wheel. I would like replace this with a multi-function, is it just a case of getting the same style, but with the buttons? Will the same Air Bag work / fit? Is the loom there for the buttons and just a case of a few clicks in VAG-COM?
