2016 Volvo V40 T5 Cross Country (4WD) with ALL the toys including adaptive cruise etc. etc. Osmium Grey with Blonde/Charcoal leather interior. Polestar performance "optimisation". (Even rarer than a D2 S8!) Oh, and a brand new engine at just under 30,000 miles on the factory one!
Finally: gone, but not forgotten.....
1998 D2 PF S8. Agate Grey/Platinum. Every option (I think) except electric rear seats, Tiptronic steering wheel, ski hatch, towbar & dimming door mirrors.
e.g. Cruise control, NavPlus/TV, Bose, GSM, Xenons, Solar roof, Parking sensors, Alcantara/leather everywhere of course. (internal dimming mirror added later)
1998 (very early) Ford Focus 1.8 Zetec; ABS/TCS, Heated screen/mirrors, Aircon. Added Auto-dim mirror, Leather seats, Trip computer, Cruise control, OEM Ford SatNav with CD changer.
And before that a lot of Rover 800s, a few oddities, a lovely Triumph Dolomite 1850HL with Overdrive and way back in my schooldays an Austin Seven aka Mini 850!

If it's a PF, which it probably is, replace the cruise unit box.
I did that on my old (PF) S8 with excellent results. Thread here somewhere about it....

I spent ages analysing symptoms trying to decide if it was the box or the stalk. Eventually decided on the box (failed caps are a common problem on other Audis with the same system) and got one from A8parts.
Local VAG independent did the job as it's a bit of a PITA being at the very bottom of the box of electronics modules under the bonnet.

It is a PF , I've emailed a8 parts any way just to see if it was tested prior to selling

Is there a way of testing the cruise control module through vag-com , I don't really want to go to all the trouble of changing it just to find out the stalk switch is faulty
