I guess the euro cars could have a different security system... on my GenII US car you can unlock the trunk with the key even when the central locking isn't working. Perhaps the deadbolt is different on the euro car?

I think the trunk lock is either bad, or you are trying to unlock it with the valet key. If you lock out the trunk from the central locking system (meaning it won't unlock when you unlock the doors), and give a valet attendant the valet key, it will not allow access to the trunk with that key.
I know that if you have the correct key, you can turn the key I think to the left, while holding the key to the left you press in on the button. But again it could be a worn lock or latch.
Now that you have battery power does the trunk unlock when you unlock the car?
I'd get it fixed, some time it might be something more important than a charger that you need out of the trunk!

Correct, it is designed so if the battery goes dead you can still access the trunk, I have never heard of a different system in other parts of the world.
You can "lock out" the trunk from the central locking system for valet purposes as I previously mentioned. To open it from the locked out position is the same as manually opening the trunk.

Car unlocks fine as long as it has some power.

Had the right key .
Read the manual to turn the key to the left.
Tried it in all positions jiggle in out in case something wasn't just right
but couldn't open the trunk.

Not sure how my security system is working but I can't open the trunk or start the car if its tripped.
Seems no power can trip it as its being disturbed & it cuts power to ignition & locks trunk.

I have to try to use it more.
Get it on the road this weekend

the Euro model does open the trunk by pressing in and turning the key counter clockwise.
