On my way back from Busfest to Scotland, I got Professional Retro Fits at Nuneaton to install cruise control to my Euro 6 DSG shuttle. Apparently there isn't an official kit available but they source the OE wiring loom and the required left hand stalk. Once fitted its coded by them. Works as if it was factory fitted with the speed and green on/off status symbol displayed in the instrument panel. Delighted with the service. Think I'll back for a multifunction steering wheel.
