Mercedes Sprinter Central Locking Problem

Have you checked the key fob battery? Also, does the car alarm still function as expected? It could be related if the central locking system is integrated.

Good point, I'll check the key fob. If the alarm is working, does that eliminate a problem with the security system? I'm trying to narrow things down before I start taking apart the door panels.

Not necessarily, the alarm might use a different circuit. If the central locking isn't working and there's an error stored, it's likely a defective component. I'd recommend getting it checked at a workshop.

Thanks for the input. I took it to a workshop. It was a corroded connector, as the error code suggested. 95€ later, the central locking is working again. I appreciate the help!
