S Klasse Door Handle Issue Keyless Entry Failure

I had a similar problem with my S Klasse. The door actuator on the driver's side was the culprit. Check the door switch and the wiring harness that connects to it. It could be a sensor issue affecting the door electronics. A broken wire within the door mechanism is also possible.

Thanks for the information. When you say 'door actuator,' are you referring to the entire door mechanism, or just a specific part? Also, did you have to replace the whole unit, or were you able to fix a wire?

I meant the specific electrical component within the door mechanism that controls the locking and unlocking. In my case, the entire door actuator had to be replaced because the fault was internal to the unit. You should get it checked at a workshop to pinpoint the error.

Thanks for the advice. I took it to the workshop, and it was indeed a faulty connection on the door electronics. The repair cost was 95€. Appreciate your help!
