I have a 2008 Pegout 207 that does not start anymore, since the car has parked for a while, I assumed it was the battery (the battery icon was flashing). Even with a new battery the car does not start, and it complains on the dashboard of a weak battery.
I connected to the ODB Port and while there are no error codes on ECU, the Battery Voltage is very weird:
There drops that can go down to 7.5Volts, randomly, this happens, without any cranking, or turn on and off devices. Monitoring the battery directly I see some steady 12.7 volts.
What do you think this may be?
