opel insignia 2014 battery dc transformer location

i have problem with insignia 2014 a20dte engine with start stop
car in standby current consumption is 0.22A and i think it is too much
when i remove fuse 43 inside engine compartment consumption goes to 0.02A
according to information from manuals fuse 43 is for "Battery, DC transformer (only vehicles with stop-start system)"
where is this module located and what is it for?
if someone have full schematics for this vehicle please let me know
when i remove this fuse instrument cluster turns off and when i check for dtcs some other modules lost communication with instrument cluster
why this fuse turns off instrument cluster?

It can happen that a single fuse is used for multiple consumers. And there isn’t space to denominate the fuse for all it supplies. 
Why removing the fuse takes off the IPC? That’s a silly question you ask, I’m sorry!

Your answer is silly friend and here is another silly question why only isntrument cluster turns off and not "all multiple consumers"??  According to information from schematics found on internet instrument cluster use another fuses and not f43 thats why i asked why this fuse turns off IC however i found the answers
Fuse 43 is for dc/dc transformer module and it is used to give stable output voltage to modules like instrument cluster and navigation etc during engine cranking (stop-start)
But i still cannot find any information about location of this dc/dc transformer module
I hope someone can give clear answer about location

problem solved dc/dc transformer location is behind instrument cluster

Did you solve the problem my friend? I have the same problem in Insignia. Did You replace the transformer DC/DC?

Maybe I can help someone with this problem. I found the fault. The rear radars in the bumper are damaged (flooded with water).
