Thanks for the reply! I haven't had the battery tested yet, but I was wondering if you recall any specific diagnostic codes that came up when you had the issue with your Peugeot? Also, did you notice any impact on fuel consumption?

I don't remember the exact codes, to be honest, it was a while ago. No noticeable change in fuel consumption, just the starting and lighting issues. Honestly, I'd recommend getting a proper vehicle diagnostics done. Could be the sensor, could be something else affecting the battery charge. Either way, it's best to get it checked out at a workshop.

Okay, thanks a lot for the advice! I took it to a workshop, and you were right, it was the battery sensor. Repair cost me 315€, but at least it's sorted now!

Sounds familiar. I had similar issues with my old Peugeot 308. The symptoms were almost identical – weak starts, flickering lights. Turned out to be the battery sensor was faulty, messing with the charging and voltage regulation. Have you tried getting the battery tested?
