How about pulling one fuse at a time while watching your inline meter. Also turn heated mirrors off (10 oclock or 2 oclock)

As much as it says in the instructions not to ..... At the end i did end up pulling each fuse 1 at a time, and the worst i did was set off the alarm and had to start the procedure again. 
I noticed when i did pull fuses like the Parking sensor, radio and TMPS the current did drop when the module mentioned above had its relay go into the on position but about the best i got was it was still pulling up over 1 amp when this occured. after pulling each fuse out of the ones on left and right hand dash.. this module was still clicking on and off. the power to this module must be fed from elsewhere.
I did not pull out the fuses out of the engine bay as i got a 0 current reading from all of these.. i also did not pull out the large 40 amp fuses unless i try this next.

Confused - please give suggestions
This will be a long post - I apologise but am completely confused re V10 batteries.
Big question: if trunk battery is starting battery, then why have trouble starting due to possible inefficient, ie maybe stuffed, battery under passenger seat?
Let the story begin.
Presently have roughly 150 000km on the clock. At about 100 000km we went on an off road trip. I had connected a 12v cable for fridge directly to trunk battery. When I connected fridge just before departure, fridge showed low voltage. Too late to do anything, so I took along genset for fridge. Car started perfectly!
On our return, dealer replaced trunk battery with new OEM. No problems since, UNTIL went camping couple of weekends ago - remember, about 40 000km later. Had fridge connected and, after one night, the next morning vehicle,on pushing start button, engine went sort of "oomph", and all lights on dash went out. Then lights reappeared and I used the key to start (without anti clockwise turn). Car started ok, but gave "engine fault" and ESP "off" light on. After a couple of km's all settled back to normal.Ok, I thought, I drained the battery with fridge.
Next weekend out, I did not connect fridge to battery. When vehicle started 2 days later, exactly same issue as described above. Important to add- the tailgate and a door left open for long periods - ie, interior lights burning!
I then left vehicle in garage for 3 days - locked, nothing opened or used. Perfect start, no problems at all!
My theory is that the passenger seat battery is stuffed. That would explain the problems when interior lights are burning, they are using the (original) accessory battery.
My question is, if the rear (starter) battery is still ok - relatively new, remember - then why have a "starting" problem? I suspect that it is some "intelligent" electronics is playing between the two batteries.
And, before I get criticism (although most welcome), yes, I should have replaced both batteries at the same time. I also intend to replace battery under seat, but the sequels of events confuses me.
To end, no, I do not have voltage readings or any of those other technical stuff you guru's are going to ask for
I will appreciate the thoughts of the V10 "guru's".
Cheers, Werner
