Did you check your batterie? I believe my problem had / has something to do with a low battery. 

Thomas if you haven't already got one buy a battery charger maintainer. I got one for a good price 50euro, it will top up (slowly) the charge of drained batteries and also is good for batteries of cars that don't get regular long drives, by way of topping off the charge keeping the battery healthy. 


I did suspect and mentioned in the post earlier that without an absolutely top condition well charged battery you may chasing a ghost problem. 


The cayenne platform seems to be one of the most susceptible cars to less than optimum battery condition. 


I now have brand new Alternator Hitachi, brand new top quality oem spec battery and use the car almost every day for 100plus km. If I do a few short journeys like move the from the basement to outside or out of warehouse to outside a few times in a row, you can tell it's having a draining effect on the battery such is the amperage draw of this engine cranking and running the subsystems. 

The alternator also has charging cycles, so hence longer journeys are key to battery life and reliability.
