A8 W12 with dead battery

[boulevard]

I have an A8 W12 with flat battery. I cannot get in the boot, so cannot get too the battery to charge it.

Any ideas how I can either get the boot open or breathe enough life into it to get it started.

Thanks
Steve

I tried that, boot doesn't shift no matter which way I turn the key.

find a 30 terminal and trickle charge, you will need a current flow diagram but probably best to pick up in the engine bay e box, later models had the battery charge posts in the engine bay

I have a black and decker battery that I can plug into the cigarette lighter socket and it powers the system can you borrow one of those or a C-tek battery charger/conditioner that uses the cigarette lighter to charge?
