2007 Citroen C3 Repair Question
Citroen C3 Battery Problem
Replaced the radio with a Sony. Worked for a few minutes then the centre display went black, windscreen wipers and headlights stayed on. Car turns over but will not start.
Citroen C3's have the ISO radio pin 4 and 7 inversed they are switchable 12V and permanant, if you inverse them it stops BIS related gremlins
If your car still wont start unplug the battery google for te correct procedure involving opening drivers window then opening bonnet, leave it open unplug battery leave a while reconnect and switch on sidelights which resets the computer.
Google it to check the exact timings and order
