Hi all, I'm wanting to change my 2005 S-Line (B7) steering wheel to a MFSW (not a FB). They keep cropping up on ebay from time to time but I wondered if anyone had that parts software thingummybob that would confirm if I needed a new slip ring and/or control unit? Presumably they would need my chassis number? Would the software (is it called Elsawin?) tell me the part numbers of what I need? Would anyone have a MFSW going spare after upgrading to a FBMFSW?
