Peugeot 508 central locking failure

Central locking on my 2023 Peugeot 508 hybrid has completely failed. None of the doors will lock or unlock with the key fob or interior button. Fuses are fine. The garage found an error stored, mileage is 38573 km. Anyone else had this?

Summary of the thread

The central locking system on a 2023 Peugeot 508 hybrid has failed, with neither the key fob nor the interior button functioning. The fuses are intact, and a general error related to the central locking module was found. A potential cause could be a defective cable or plug connection in the door wiring harness. It is recommended to have a professional workshop handle the issue to avoid further complications.

I had a similar issue with my 508. Check the door wiring harness, especially the plugs. I've heard a defective cable or plug connection is a common cause. Was that the error that came up? Did they specify which door?

Thanks! They didn't specify which door, just a general error related to the central locking module. Where exactly is the door wiring harness located? Can I access it myself without dismantling the door panel?

It's inside the door, running from the car body into the door itself. Honestly, it sounds like a job for a workshop with the correct tools and diagnostic equipment. I ended up taking mine in, saved me a lot of hassle.

Appreciate the advice! You're right, fiddling with the wiring myself might make things worse. I'll book it in with an auto-electrician. They quoted 95€ for diagnostics and repair, which seems reasonable. Thanks again!
