I have a Fiat Doblo 2015 (263) with a Delphi BCM.
The 2 front doors will not open via the 3 button remote - but the side lights flash to show signal received and i can hear a relay click but that may be the flasher.
The doors lock OK.
They stopped working immediately after resurrecting the car with a jump start following 2 months of lockdown.

Can open the drivers door with key but passenger stays locked unless it's opened from inside.
Nothing obvious to be seen, tried a long car battery disconnect to see if things reset but no joy.
Looms at the door hinges looks intact.
No flashing dash lights.
Can't find a wiring diagram which is a major issue for fault finding.

As an option would it be possible to use the separate cargo door unlock signal to open the front doors.
All doors would then open on the cargo door button.
There is no alarm on the car that may have complicated this possibility.
