Firstly at €875, I'd just buy a normal GTI DSG steering wheel for £300 and get it recovered for £120 odd, and cruise control can work on them through specialist coding (Alex Retro does it in England) but for the most part you can't get it working from the steering wheel. I think you can just keep using it from the stalk though.
Yes Alex is local to me, the mk5 steering wheel looks it age now, I really prefer and like the gti clubsport steering wheel.
If you bought the controller board off Alex today congrats!
Secondly you can get regular cruise control working on the wheel as far as I know it just doesn't do adaptive.
I too am on the hunt for a new steering wheel, though finding a GT badged mk7 DSG paddle MSFW is a nightmare.
I was one of them indeed! Reading threads from a couple months saying it was no longer possible was a real downer, didn't want to take any risk and miss out on what was needed to get it all working.. I just wasn't expecting to pay what I did for it though eeeek!!
That's good news, when I get some extra cash to spare I'll get the clubsport steering wheel, can't wait!
P.s any particular reason why your only settling for that steering wheel?
