Door locking, Yes i've searched, no it's not the door control module

Hi, my situation is as follows:

 

- Centrally unlocking the doors with the key in either door works fine. (the opposite door unlocks too)

- Centrally locking the doors doesn't work. (I have to walk to the other side and lock it manually)

- Pushing the buttons inside the car only works unlocking it too. (next to the electric window controls in the driver door)

 

BUT:

- both doors do get locked when I disconnect the battery. (So it's not the mechanism or control motors or anything)

 

AND:

- I've tried putting in a different Door Control Module (a blue one, mine originally is red) but this has made zero difference.

 

So I'm thinking the problem must be somewhere in the route from the door contacts to the Door control module or ECU?

I'm trying to find the appropriate schematics, but it's pretty cut up within the manual, you have multiple pages concerning this topic.

 

If anyone has had the same or similar problems I'd be happy to know how to fix it or test certain things.

 

cheers
