Problem with open/closed door sensor?

[obolikol]

Hi,
I have a problem with my c5 x7 2009r. The Computer thinks that the doors (driver side) is closed at all times. I took off door panel, and unplugged the lock harness, the switch inside seems fine, but when i plugged it back in car told me that the doors are open, even when closed and it wouldnt lock from the pilot. But after a few hours it disappeared and it locked without any problems (now it thinks that are closed at all times again).
Please help!

You need to check the wiring harness as it enters the door - inside the tube protector. Wires can become worn and can break from opening and closing the door.

Do you maybe have diagram for the plugs from the lock and the combined from the doors?

I checked without diagram. And the connection between plug and other plug is good.
What else could it be?

I've been a little busy today, but here's the diagram. You only have Simple Central Locking (so ne deadlocking on this vehicle).

With the exception of the wiring codes, most of the component codes are indexed here:
