306 Remote locking stopped working

Window and mirror electrics work ok..will have to wait til daylight to check condition of the umbilical

Could be the solenoid burnt out, it can also be the wiring at the door hinge. Just open the door fully. Open the umbilicle connector and check the condition of the wires inside: that's where they break. It can also affect any other system in the door usually it's the windows.

Yeah, same thing happened to me with my 306. Thankfully my fault is that all when locking the driver's door with a key only the driver's door locks. Unlocking the driver's door with a key opens all the doors. Using the remote fob locks and unlocks all doors correctly.

I'm assuming that the wire which broke is the signal to the central locking system that the driver's door has been locked. The unlock signal, and the locking request signal both work fine. Consequently, it means when using the key, we have to lock the passenger's door, as that will lock all the doors.

I've yet to try looking at the wiring at the hinge. I've checked the wiring in the door + locking mechanism - so the fault lies in the hinge wiring, or within the wiring in the chassis, or the central locking unit. Personally, I'm going with the hinge wiring.

Sorry but you will have to remove the trim,i had one go on my 405 and when i removed the trim all i had to do is spray wd40 over all of it and it has not played up since.

Trim to what? I've removed the internal door panel, exposing the wiring and the locks and checked all the exposed wiring which is fine. Spraying WD40 therefore in that area won't make a difference, there's a break or similar problem between the hinge and the central locking unit. If you're referring to trim other that that on the door, could you be a little more specific?

thanks

Try and remove the central locking unit, if you can get to it .or cut the wires just into the door and rewire them into the main loom by the door hinge, good luck from chris Addlestone
