Re: Battery draining problem
It would appear that you have something not turning off properly when you switch off. The first thing I'd do is a BSi reset following the procedure in the link below. If the fault is still present after that you will need to isolate which circuit is still active, possibly by removing fuses one by one until the fault clears. Most times this type of failure is due to dampness or corrosion in a connector somewhere so check all the fuseboxes for those issues and see what you find.

Re: Battery draining problem
There may well be a multi-plug on the fusebox that carries all those circuits and has been infiltrated by damp or something.

Re: Battery draining problem
I cannot see the fuel low level light in the pictures unless i am not seeing the obvious which is something i am well known for.
Is the AirBag light for the passenger side? Both of the seatbelt/airbag lights are close together so could be light bleed if very faint but could be on a similar circuit for the ECU ?
To drain the battery in 5 hours is a heck of a drain. Have you checked earth strap points?
Just throwing out some thoughts, not technically qualified but i have owned a various number of Citroens

Re: Battery draining problem
The terms you mention are in the subsection headed:
For C5 X7 Tourer V6 Engines, with / without motorised tailgate or vehicles where the battery is in the rear boot:
So don't apply to your van.

Re: Battery draining problem
Since the only vehicle mentioned in your signature is a DS3 it would be sensible to confirm the full details of the vehicle you are talking about

Re: Battery draining problem
Totally random thought but interior lights are i guess one of the things that wake up first when unlocking the vehicle. A cheap first experiment would be to remove all of the interior bulbs( including those in the boot area ) and see if the drain is still there. If the drain is still there i would then still leave them out and remove all of the rear light bulbs, including number plate ones and see if the drain is still there.
A blown bulb can short to earth and become a right PITA.
