Mercedes M Klasse Hybrid Keyless Entry Problem
Summary of the thread
A 2011 Mercedes M Klasse Hybrid experienced a keyless entry failure, with error codes indicating issues with door handle electronics on all doors. The problem was suspected to be a wiring fault or a faulty plug connection. A similar past issue suggested inspecting the wiring harness and connectors. The problem was resolved at a workshop, where a faulty plug connection within the door mechanism was fixed, restoring the keyless entry functionality.

When you had the issue, was it all doors at once, or just a single door handle? Also, did you manage to fix it yourself, or did you end up taking it to a shop?

In my case, it affected a single door. Given that your issue is present across all doors, it might indicate a common point of failure, such as a central wiring harness or control module. I opted for a workshop visit to ensure correct diagnosis and repair.

I took it to a workshop, and you were spot on. It was indeed a faulty plug connection within the door mechanism, which they fixed for 95€. Keyless entry is back, and no more error codes! You saved me a ton of time and stress!

I had a similar issue with my M Klasse. The symptoms you describe point towards a defect in the door handle wiring or connector. I would advise a thorough inspection of the wiring harness and connectors within the door mechanism.
