that is a European Audi RS6 steering wheel that I got through
www.europrice.us. Europrice modifies 1 pin in the harness to make it plug and play on the D3. Paid about $1350 for it including a new airbag as the old one would not fit. I put it in myself with a triple square bit, really easy. Unfortunately I left it on the car when I sold it. The guy at Europrice I dealt with was Alex, and you really need to do it through email, he does not have this stuff on his site. I have his email
contact@europrice.us i believe
sorry for the late reply, sold my car and have not checked this in a while
