Every so often when I start my car it's saying electrical circuit system: have the vehicle repaired, and in the diagnostic menu it's saying battery fault system. I've had my alternator tested that's fine, also replaced the battery, I've also done a bsi reset and had the car plugged in to a Peugeot diagnosis and still getting no answers its a 308 15plate 2.0 diesel. the car is having no issues with starting either and I've looked on forums and most that seem similar are having issues with starting the car or certain components working but that's not an issue currently
