Hello Audiot
First of all: Very well documented and good initiative
!
From what I've read so far I deduce that boot lock motor V53 is O.K. but you have a problem/shortage in the wiring.
The reason beeing that always both signals (locked/unlocked) are on or off at the same time. This can be caused by a shortage or a loose (floating) ground connection !
The wiring error is located somewhere between motor V53 and control unit J256.
Pin 1,2,6 (belonging to the micro switches) of the boot lock motor connect to a green 3-fold connector in the lid.
The signal of Pin 6 is then conducted by a brown 1,0 sqm cable to another red 2-fold connector in the trunk lid. This connects to 0,5 sqm ground connection in the boot loom.
The 2 signals of Pin 1+2 end in a green 6-fold connector in the boot itself, right side.
Now several measurements have to be taken
Remember, that with a faulty boot loom measurements can vary between open and closed state. But you said that you replaced the loom already. (With what ? Both sides ?)
Best of luck

Now several measurements have to be taken
- Green an red connector in boot lid securely plugged
- Is Pin 6 of the V53 plug really connected to ground with low Ohm's ?
- Is a shortage between Pins 1+2 of V53 plug measurable, when green 6-fold connector in the boot is unplugged ?
- Is a shortage between Pins B13+B14 of J256 plug measurable, when green 6-fold connector in the boot is unplugged ?
