Electronics problems and battery weakness in 2016 Benz E Class: experience and solutions wanted

Hey guys, I have a problem with my 2016 Benz E Class with 174,091 km down and a gasoline engine. Electronics are spinning, errors are stored, lights are flickering and the battery is weak when starting. It used to be like this, my mechanic said something about terminal 30 being interrupted. But I didn't have any good experiences, so I'm asking here. Have any of you had similar problems and how did your garage fix it? Thank you very much!

Summary of the thread

A 2016 Benz E Class owner is experiencing electronic malfunctions, flickering lights, and a weak battery, with a mechanic previously suggesting an issue with terminal 30. Another Benz owner shared a similar experience, where a faulty battery sensor with a loose connection caused similar problems, and replacing it resolved the issues. The suggested solution is to check and possibly replace the battery sensor, which previously cost €315, leading to a stable and problem-free vehicle operation.

Hey buddy, I drive a 2013 Benz C-Class and had a similar problem to yours. I had a faulty battery sensor. This caused my electronics and lights to go crazy. The mechanic said the sensor had a loose connection and had to be replaced. The battery was also low at the start, just like yours. I can tell you, it wasn't a minor issue. But after the repair, everything ran smoothly again. Hopefully my experience will help you a little. Good luck!

Hey, thanks for the tip, sounds pretty much the same as mine right now. How much did it cost you, if you can still remember? And have you had any more problems since the repair or was everything quiet after the battery sensor was replaced?

Hey, I'm glad if I can help. I had to pay €315 to repair the battery sensor. It wasn't cheap, but it was definitely worth it. Since the mechanic solved the problem with the interruption of terminal 30, everything has been running like clockwork, no more bitching from the electronics. So far nothing new has come up either, so you could say, yes, peace in the box. Hope it works just as well for you!

Great, thanks for the info! That gives me confidence that the problem can be fixed without falling into the garage's rip-off trap again. 315 is quite a lot, but I'm comforted by the fact that you didn't have any more problems after the repair. That gives me hope. So, off to the garage tomorrow and fingers crossed that it's nothing more serious. But with your tips in mind, I feel better prepared!
