V Klasse keyless entry malfunction

I've seen similar symptoms in my V Klasse My locking system failed due to a sensor issue in the electric door's wiring harness The CAN bus signal was disrupted by a wiring fault Inspect the door electronics wiring, especially connectors and insulation Have you done any diagnostics besides reading the error code

Thanks for the reply I haven't done any other diagnostics Can you tell me more about the sensor and how you found the wiring fault

The sensor is part of the keyless entry module in the door handle assembly I found the fault by testing each wire in the harness for continuity and looking for corrosion or damage If you don't have much diagnostic experience, a technician should do a full check A defective cable or plug connection is likely In my case, the workshop found a similar issue and the repair was around 95€

I appreciate the explanation I'll get a technician to check the door handle electronics and wiring harness Thanks for confirming the price, it gives me a good idea about the cost The problem was a defective connector as you suggested, and was replaced The system is working again
