Hall sensor malfunction in the Benz EQC 2018: experiences and suggested solutions wanted

Locking/Unlocking issue

Warning light in the speedometer of the vehicle

Car won't start

Hi guys, Do you have any experience with ignition key hall sensor malfunction issues on a 2018 Benz EQC with gasoline engine and 155,451 km on the odometer? Mine shows a warning light on the speedometer, has locking problems and sometimes won't start. After my last visit to the garage, I'm a bit skeptical and would like to draw on your experience. Has anyone had a similar experience? How did you deal with it and what did the garage say? Thanks in advance for any tips and advice.

Hey, I drive a 2015 Benz GLA myself and also had the same problem with the control unit malfunctioning. It turned out to be a pretty serious problem. When my car showed the same symptoms, the trunk no longer closed properly and warning lights were on, I took it to the garage. The guys there completely replaced the control unit. It seems to be a common problem with these models. I would advise you to go to another garage or discuss it with your existing garage. Hope this helps you. All the best with your car!

Hey, interesting that you had the same problem. That's pretty worrying. Can you remember what you paid for the repair? Has anything else come up since the ECU was replaced? Thank you!

Hey, sure, no problem! The repair for the control unit cost me €600, which was quite a lot. But since the replacement, my Benz has been running like clockwork again and I've had no further problems. As for the Hall sensor for the ignition key, I had that problem too, but since the last visit to the mechanic it has been fixed. So yes, you can say that the cost was hefty, but in the end it was worth it. My tip would be not to hesitate when the problem occurs and get it fixed as soon as possible. Hopefully this will help you and you'll soon have no more worries with your car!

Hey, thanks for the info! It does sound like expensive fun, but if it solves the problem and saves me future headaches, I guess it's worth the money. I guess I won't hesitate any longer and take the car in for repairs. Thanks again for your advice, hopefully everything goes smoothly with my car! See you then!
