S40 Central Locking Failure

Hi, I have a 2005 Volvo S40 with a gasoline engine. The central locking has stopped working. The doors can no longer be locked or unlocked, and there's an error stored in the error memory. I suspect a defective cable or plug connection. Has anyone experienced something similar?

A 2005 Volvo S40 is experiencing a central locking failure, with the doors unable to lock or unlock and an error stored in the system. The suspected cause is a defective cable or plug connection. A similar issue in another vehicle was resolved by addressing a faulty connection in the door wiring harness. It is suggested to check the fuses and wiring loom, and if unresolved, consider professional repair, which is estimated to cost around 95€.

Hey, sounds familiar. I had a similar issue with my old Opel Astra. The central locking went haywire, and it turned out to be a faulty connection in the door wiring harness. Have you checked the fuses and the wiring loom between the door and the body? Maybe it's a simple fix.

Thanks for the tip! Which connection was faulty in your case? Was it obvious, or did you have to measure the voltage?

I didn't measure the voltage, to be honest. It was a broken cable in the door wiring harness. I couldn't fix it myself and decided to go to the workshop. Cost me around 80€ if I remember correctly. I would recommend going to the workshop.

Alright, thanks for sharing your experience. I will check the wiring harness, but probably take it to the shop. They quoted me 95€ for the repair, so that sounds reasonable.
