Mercedes GLC Diesel Battery Issue

I had similar issues with my GLC. Check the battery sensor. Was it a dead battery?

Thanks for the quick response! So, it sounds like you had the exact same problem? When you say check the battery sensor, what exactly do you mean? Did you replace it yourself or take it to a shop? Was it a low battery beforehand?

Yeah, same symptoms. I took it to a workshop. They confirmed it was the sensor. I'd recommend doing the same, before doing something wrong.

Alright, thanks a million for confirming! I really appreciate the advice. I bit the bullet and took it to the workshop and you were spot on – faulty battery sensor. They replaced it, and everything's back to normal. That 315€ stings a little less knowing I wasn't chasing ghosts. Cheers!
