Hello all, I have a standard S line 3 spoke non multi function steering wheel fitted and have just purchased a flat bottom steering wheel with multi function buttons. The new wheel part number : 8JO 419 091G and circular airbag part number: 8JO 880 201N. My 2007 A3 has RNS-E and Cruise control, will I need a loom or slip ring etc to make everything work as it should? I'm aware I have to code in the new wheel, is there a how to guide anywhere? Cheers Rob.
