Renault Espace weak battery flickering lights

Sounds familiar! I had similar issues with my old Peugeot a while back. Weak starts and dodgy lights. I thought it was the battery itself, but... a sensor?

Interesting. What Peugeot model was it, and did the diagnostics specifically point to the battery sensor in your case as well? I want to be sure before replacing it. I'm trying to gather as much info as possible.

It was a 308. No diagnostics back then, just a gut feeling after some research online. But yeah, replacing the sensor fixed it. It's worth a shot or take it to the workshop.

Thanks for sharing your experience! Based on your feedback and the diagnostics, I decided to replace the battery sensor. That seems to have fixed the issue. The total repair cost me 315€. I appreciate the help!
