2012 Audi A1 MFSW into 2008 A3
Im actually in the middle of doing this myself, but have come to a complete stall.
You're correct in that:
Pin 1: Data
Pin 2: +12v
Pin 3: GND
Bare in mind that we cant change any of the pins in the slipring plug as this would alter what the car receives, which we obviously cannot change.
I tested the continuity on Pin 3 to confirm the ground which leaves only Pin 1 and 2.
Ive tried both combination in my 2007 A3 running a 'F' module, with no luck.. I dont even have lights on the wheel at all!
My theory is that its purely incompatible, cant really think of any other solution...
