After 6 happy months of ownership and 6k miles the Beast has decided to prove that I should have perhaps bought a Cayenne GTS

Last Thursday my wife was stranded at the Station car park with a flat battery completely out of the blue. As a side note, on the Sunday we had just come back from 10 days in France where we covered 1350 miles sans trouble, including a 600 miles dash back. Jump started the car, went home, stuck a CTEK to the jump terminals and thought nothing more of it. The next morning, she disconnected the charger, drove the kids to school and herself to the station and yes, that evening she called me again to tell me the car was dead. The GT3 came out of the garage, I jump started the bus and she came back home.
Then I realised I needed to do more work. I think it is not the blower resistor. The car simply does not want to fall asleep within its allocated time - sort of like my 2 and 5 yrs old. But joking aside, here are my thoughts:
I suspected the NAV DVD - its light is on 30mins after the car has been locked. And I can also see the screen almost flicker into life only for it to go back to completely off. I pulled the fuse. Car went to sleep but it took absolute ages. Like 2hrs.
Secondly, while driving today and listening to the CD Changer, every 2 or 3 mins or so, it would disappear. Completely. Not to be found even as an option - suddenly I had tape and radio, no CD Changer showing at all. Then if I wait and press the Mode button again, it would come back on, only to disappear soonish. Took the radio module out - dry as a bone and no signs of water ever been there, but who knows?
Third, when I open any door or tailgate, all lights inside come on, except rear left passenger. The bulb is good, as the light can be switched on manually. Could it be a problem with the GM3/LCM?
Where am I now - 1h 45min, DVD Nav fuse out, radio module out, alarm on, no lights or anything on, yet LED next to gear lever still winking at me with its orange eye. Yet, earlier on we went out for a family meal, spent 2hrs in the Restaurant and when I came out, the LED was off, in other words, the beast was sleeping.
Any ideas or a specialist in SE London/Kent who can help?
Many thanks in advance,
Alex
