Citan electric low battery warning

I'm having some trouble with my 2023 Mercedes Citan electric engine I'm getting a 'low battery' error on the dash The lights are also a bit weak and flicker sometimes I checked the error memory and there's something stored there related to the vehicle battery When starting, it feels like the battery is really struggling I've checked the battery terminals and they seem ok Any ideas what could be causing this battery drain

Sounds familiar I had a similar thing happen with my Citan Low battery warning, dimming lights, the whole shebang Have you thought about the battery sensor I had a persistent vehicle battery issue that turned out to be a faulty sensor It was causing all sorts of weirdness Is it possible that's your problem too

Interesting How did you figure out it was the battery sensor Was it obvious, or did you have to do some digging What steps did you take Did you measure voltage across the battery terminals

It wasn't obvious at all I initially thought it was a bad connection or something After the usual checks, still had the same problem I took it to a workshop, and they diagnosed it pretty quickly with their diagnostic tools They said it's a common issue If I were you, I'd get it checked out properly before you end up stranded Cheaper than replacing the whole vehicle battery for no reason

Thanks for the advice I took it to a workshop, and you were spot on Turns out the battery sensor was defective They replaced it, and the error is gone, lights are bright, and it starts like a charm Cost me 315€ all in Appreciate the help
