Insignia Battery Drain

I've got a 2019 Vauxhall Insignia, gasoline engine, and it's been giving me grief. The battery keeps draining. I'm getting error messages on the speedometer, the lights are weak and flickering, and the error memory has stored a fault. Starting is a real chore due to the weak battery. Mileage is at 148043 km. Anyone else had similar issues?

Could be a few things. Is it completely dead, or just struggling? Have you checked the terminals are clean and tight?

It's heavily discharged, definitely not just struggling. Terminals are clean. Any ideas beyond the usual suspects?

Right, heavily discharged points more to a parasitic drain or a faulty battery sensor, maybe? I'd say it's time to get it looked at by someone who knows their stuff, just to be safe.

Thanks. Turns out it was a defective battery sensor as you suspected. Cost me 315€ to get it sorted.
