Peugeot 207 Battery Drain

Hi, I've got a Peugeot 207 diesel from 2008 with 114065 km. The battery is heavily discharged. I'm seeing an error message on the speedometer, weak lights, and a stored error. The battery seems weak when starting. I think the battery sensor might be bad. Any ideas on what could cause this or how to diagnose it?

Whoa, sounds familiar! I had almost the exact same thing happen with my 207. Battery kept draining itself. Did you check the battery terminals for corrosion? Also, maybe get the battery charging system tested. Just a thought!

Thanks! When your battery drained, did the diagnostics point to a bad battery sensor, or was there something else? I'm trying to figure out if replacing the sensor will fix it.

Honestly, I couldn't figure it out myself. Tried cleaning the terminals and even charged the battery, but nothing worked for long. Finally, I gave up and took it to a workshop. They said it was something draining power when the car was off. Best to get it checked properly.

Thanks. Based on that, I'll get it checked out at a service facility. Sounds like a more thorough look is needed. I appreciate the help.
