The voltage was reading 10.8V, but it started fine! I would get a trickle-charger but there's nowhere to plug it in near my car!
It was clearly in some form of low power mode when I first unlocked it: Interior lights not working, and seat didn't move from the comfort entry position to my driving position until I pressed the memory switch on the door. Otherwise no problems and I drove around Bucharest for about an hour until Start-Stop started kicking in, then a bit more for good measure.
I also visited our local (only) Romanian Porsche dealer. Got the VIN checked for recall (needs DME update apparently) and got a quote for first service of €588 (about £500) which includes extra filters (due to dusty environment) and also Brake Fluid change. Seemed reasonable.
Lots of impressive cars at the OPC - new model Panameras, lots of Macans, loads of Cayennes. I sat in the showroom panny - black with (presumably) agate leather interior (very brown) and wood trim - colours not to my taste but a nice environment nevertheless!
Going for a longer touristy drive tomorrow, probably Transylvania. If my wife permits me to take them, photos will follow!
