I did not and my car does not have climatronic. I have seen it posted here that someone with basic climate control had the panel with heated seat/heated wheel buttons, an early EU Mk7 with "winter pack" but I never could find a part number for that panel. Even in the EU heated steering wheel was later tied to having climatronic. I'm sure part of that is that climatronic can press the A/C menu button which brings up the infotainment climate control screen and there are heated wheel options in there. No way (that I know of) to access that menu on car with basic climate control.Did you change your climate control panel to the Heated wheel one?
Luckily the Mk8 wheel has its own steering wheel heat button (it's a CAN bus command in any case, or in the case of the steering wheel it's LIN bus to CAN bus). I have also heard that climate control panels without the heated wheel button will turn on the heated wheel anytime seat heat is on, have not tried it.
