Peugeot 208 Overvoltage Errors

Hi, I'm having a weird issue with my 2023 Peugeot 208 (electric engine). I'm getting a lot of overvoltage errors and it's causing all sorts of problems. The car keeps throwing fault codes, various systems are failing, and the battery seems weak when I start it. It generally feels like a gremlin is messing with the electronics. Has anyone experienced anything similar?

Whoa, that sounds rough! I had a somewhat similar issue with my 208 a while back. Lots of random electrical weirdness. Overvoltage, huh? Like a dam about to burst! Was the battery light on, or anything else besides the fault codes?

No battery light specifically, just the error codes popping up on the display. Where you getting the same overvoltage errors, and what was actually causing it?

Okay, no battery light is interesting. I was getting overvoltage errors, yeah. Turns out my battery was heavily discharged, borderline defective. It was like trying to run a marathon on an empty stomach. Because the voltage regulator was going crazy trying to compensate, it was throwing all kinds of errors. Honestly, I'd get it checked out at a workshop ASAP. Could save you a bigger headache later.

Thanks a lot for the insight! I took it to a workshop, and you were spot on – turns out the battery was indeed faulty and causing the overvoltage. They replaced it, and everything seems to be working fine now. The bill was 290€ Appreciate the help!
