In anticipation of the cold weather I've just tried swapping my summer and winter wheels. Didn't get any further than the locking wheel nut. I can't see a way of getting a reliable purchase on it using the supplied adapter. Is there a knack to this that I'm missing? I tried locating it and then tapping it gently with a hammer. That gave me enough seating to undo it but then I couldn't get the adapter off the nut. Am I doing something wrong?

No, you are not doing anything wrong. I don't know the year of your Cayenne, but mine was new in 2014. I had exactly the same problem, only worse in that the locking wheel nut adapter, appearing to be made of soft aluminium, actually split. Sadly not of Porsche's usual high engineering standard.
My solution was to buy four ordinary wheel nuts.
How to remove yours? Once you have the additional conventional nuts, I suggest you take the car to a friendly tyre dealer. This problem is not new, they may be able to remove the locking wheel nuts.
But now with ordinary wheel nuts my wheels might be stolen? Yes, it is easier, but my Porsche Centre at Silverstone report that this is almost unknown. The wheels are of sufficient size to deter almost all but the most determined thieves.
As you will be changing your wheels twice yearly, get some copper grease to smear onto the threads, which helps removal and refitting. Use a torque wrench to tighten the nuts opposite each other to ensure correct seating. For safety, check the torque again a week later.
I trust this helps.

I have had similar issues and no you are not doing anything wrong. In my case, over the years on different Cayennes, I have had the locking wheel nut split/give way on 3 separate occassions - each time Porsche have replaced it (and bolt as well). I use a socket extender to give better purchase and to give me a little space from the wheel.
It does seem to be a design fault. I now torque the locking wheel nut at a slightly lower level than the other ordinary bolts.
Did not know about the copper grease so thanks for the tip.

] As I recall, copper grease has some sort of adverse chemical reaction?
Thanks for the advice - good to know I'm not the only one! Mine is a 2015 car by the way. I think I'll get the locking wheel nuts replaced with normal ones. I'd rather take the risk on the wheels being pinched than end up stranded with a puncture I can't fix.
