Seat Formentor Hybrid Battery Drain Issue

Having a weird issue with my 2021 Seat Formentor hybrid. The vehicle battery keeps getting heavily discharged. I'm getting an error message on the speedometer, and the lights are weak and flickering. Diagnostic check shows an error stored in the memory, and the engine is weak when starting. Suspect it's the battery sensor. Anyone else experience this kind of battery drain?

I have a Formentor as well, though I'm not sure of the year. I experienced something similar not too long ago. Error messages popping up, lights acting strange. Did you check the battery terminals for corrosion? That was my first thought.

Interesting. So, did cleaning the battery terminals fix it for you? Or was there more to it than that?

Cleaning the terminals didn't solve the problem. The issue was a defective battery sensor causing excessive battery drain. I'd recommend getting it checked out at a workshop. They'll be able to properly diagnose the vehicle battery and electrical system.

Just wanted to let you know that you were right. Took it to the shop, they confirmed the battery sensor was defective. New sensor installed and the electrical system is behaving normally again. Cost me 315€. Thanks for the help!
