Jumper Battery Draining

Hi, I've got a 2015 Citroen Jumper, diesel engine, with a weird battery issue. Mileage is 182103 km. The battery keeps draining heavily. I'm seeing an error message, lights are weak and flickering, and the error memory has stored a fault. Starting the engine is a struggle. Any ideas?

I had similar symptoms on my Jumper. Have you checked the battery terminals and the vehicle battery itself? Maybe try fully charging the battery with an external charger and see if the problem persists?

Thanks for the tip! Terminals look okay, and I did try charging it, but the issue returns after a short while. Could it be something other than the battery itself?

Yeah, sounds familiar. In my case, it turned out to be a defective battery sensor constantly draining the battery. Best get it checked out at a workshop; they'll be able to pinpoint it properly. Cost me around 315€ to get sorted.

Appreciate the insight! Sounds like a battery sensor issue. I'll get it booked into the workshop to check the electrical system. Cheers!
