Prueba con este procedimiento :
Resetting the BSI computer:
Open the driver's window and the bonnet.
Close all the doors, switch off everything, like the radio, phone charger etc.
Remove the ignition key via the open window
WAIT 10 minutes
Disconnect the battery.
(change the battery at this point if this is required, otherwise WAIT 30 seconds)

WAIT 1 minute
Keeping the doors closed, lean in via the drivers window
Switch on the 'ignition' (Don't start the engine)

El Citroen también tenía la batería full fondeada; hasta la ECU había que desconectar para poder sacar la original y cambiarla
