The lights on the console are a sign that the cars not going to sleep and is constantly sucking the life out of the battery.
I have had door handles do it too me, i've seen on the internet things like bad instrument cluster, tv tuner, water in mmi panel, faulty alarm and probably more that can cause this so its just a matter of figuring out whats pulling it down.
Have a look at the attachments, give you a place to start.

Hmm ok sounds logical, but when you say you've had door handles do that to you. What did you end up doing there? Disasemble the door handle and swap out the switches and coat it up with some conformal coating afterwords? Or swaping out the entire handle? Never had the door panels, let alone the handles of a D3 before so i have no idea how there made lol.
Thx for the doc's mate! I hope i get some time this weekend to reflash the MMI and hopefully get that working so that i can go on with the messuring the drain =/
