Peuegot 508 problem with drivers door

[Guinek]

Hi,
Problem with the driver's door lock, the car does not detect whether the door is open or not.
I got error B173A 00


The lock has already been replaced because the previous one did not lock the door

Check for broken wires in the harness that goes between the door & body by the hinges. As the wires are constantly flexing this can be a common weak point on most cars.

Did you get the drivers door fault fixed? If so what was it as my car has same fault on a 308 1.5 diesel 2019.
