I'm doing a bit of research into fitting a mfsw wheel to my s3 8l from what I can gather I need I single phase airbag so the 8v steering wheel is probably the easiest. I have a rnse retrofitted so would like to get the mfsw sorted the what steering wheel ecu would I need and airbag wiring harness will one from a 8v work. Also the rnse is coded as in an a6 so would this still talk to the steering ecu or would I need an a6 ecu. Their doesn't seem to be any retrofit guides on this
