Skoda Fabia: Assessing Standby Power Usage of Added Electrical Components

Hello. I added a few things in the car that require electricity. To three of them I added such switches (I add an attachment, it's something like that)
Do they draw any electricity even when they are turned off? Somewhere I read something like this and it doesn't give me peace, besides I added usb, but there is nothing plugged in and I added the radio. All these things are plugged into the radio cables there. When I wanted to check the current at a standstill, the meter showed me 310mA which is a very large value, after removing the fuse from the radio only 130mA, although still too much. I also added a lock on the remote control but wrote that it should charge a mountain 8mA at a standstill.
Also, I want to know if these switches draw some current and if I installed the USB converter, does it download something when nothing is connected to it, because if not everything is to blame for the radio and it consumes over 150mA. Besides, how do you find what gets the remaining 130? Pull out all fuses in turn and take measurements?

Unfortunately, but you have to do it. All fuses in turn. I also struggled with a large consumption. Here is the description of the subject https://www.elektroda.pl/rtvforum/topic3380867.html#16729670 Good luck !!

Attach everything you can under the key and the problem will solve itself.

This usb will switch and the radio may be under the key, but do these switches consume electricity? There are no LEDs or anything, the most ordinary (I added a picture) Because it gives me no peace

Start by connecting the radio to the key

The power switches themselves do not draw (as long as they are working).

And sometimes you don't have LPG installation? Because the controller can draw approx. 150 mA.

In the Vag group, the most common reason for the power consumption at a standstill is damage to the microswitches in the door locks (the comfort module does not put the system to sleep if it cannot see the location of the door locks. Check if the interior lighting reacts to all doors.

I have an LPG installation. The case looks like this, all the things that I installed do not consume electricity except a radio that pulls about 160mA. 6mA probably pulls the central locking controller, there is still 140mA left. After pulling out the fuse 43. (central controller, automatic transmission control lever lock, 20A), this 6mA is probably left. I don't know if this fuse 43 is this, but I found it on the net. Should this be the case and does this driver fall asleep after some time? If so, after what and what should the consumption be then?

Lift the ignition cube and see if the current drops.

Where is the cube?

Connect the meter and check after 15-20min what the consumption is.

Remove the ignition cover and switches and you will see the ignition cube.

The comfort module is connected to fuse No. 43. Maybe this will help solve the problem: https://www.elektroda.pl/rtvforum/topic2944525.html
