SOrry I can't give you any definite answers, I put a mk5 MFSW into my '06 Caddy and that required a new steering wheel controller unit
But when I put a GTI steering wheel with flappy paddles into my '10 Maxi Life (which already had MFSW) it didn't need a new controller. You just need a computer to 'enable' the paddles. Best mod, changes the whole feel of the car!
