Peugeot 5008 battery discharge

That sounds frustrating. I had a similar issue with my Audi A4 a while back. Same symptoms: the car struggled to start, and the dashboard lit up. Did you check the battery terminals for corrosion or loose connections? Also, have you tried jump-starting it to see if it holds a charge?

Terminals appear clean and properly connected. I jump-started the car, but the issue persists after turning off the engine. Does your experience align with this behavior?

Yes, that's exactly what happened to me. Jump-starting was only a temporary fix. Eventually, it turned out to be a faulty sensor draining the battery even when the car was off. Given your symptoms and the jump-starting results, a visit to a workshop is probably the best course of action to properly diagnose and replace the faulty component. Don't let them just replace the battery; insist they check the sensor!

Appreciate the confirmation. I took it to a workshop as you suggested. The diagnostic confirmed the battery sensor was defective. The repair, including parts and labor, came to 315€. Thanks again!
