Fiat Fullback Battery Draining

Hi, I'm having a weird issue with my 2020 Fiat Fullback diesel. The battery keeps draining. I'm getting an error message on the speedometer, the lights are weak and flickering, and the error memory has a fault stored. Plus, the engine is struggling to start. Mileage is 90098 km. Anyone experienced this?

Sounds familiar. Had something similar happen with my old Skoda Octavia. Battery kept dying on me. Did you check the battery terminals for corrosion?

Yeah, I checked the terminals, they seem clean. Could it be something else causing this battery drain?

Could be a faulty battery sensor. Had the same issue with the Skoda. Ended up taking it to a workshop. It cost around 250€ back then. Save yourself the headache and get it checked.

Thanks for the tip! I'll get the battery sensor checked out. Turns out that was exactly the problem, the sensor was defective! Cost me 315€ to fix, but at least it's sorted.
