Zoe Overvoltage Faults

Sounds familiar! I had a similar problem with my old 2008 Peugeot 207. It drove me nuts! Did you check the alternator? While the Zoe is electric, a faulty 12V battery or its charging system could cause power surge and all sorts of weird electrical gremlins. Does it happen at specific times, like when you use certain functions?

Thanks for the quick reply! You mentioned the alternator on your Peugeot – where is the equivalent component located in the Zoe, and how would I go about testing it? Is it something a novice can do, or should I leave it to the professionals?

Ah, on the Zoe, there isn't a traditional alternator like in my old Peugeot, it's a DC-DC converter that charges the 12V battery from the main battery. Honestly, diagnosing issues in electric vehicles can be tricky. Given the overvoltage codes and the potential for damaging sensitive electronics, I'd strongly suggest taking it to a workshop. Better safe than sorry!

Thanks for confirming. Sounds like professional intervention is needed. I'll take it to the shop. The repair ended up costing me 290€. They replaced the 12V battery.
