Rather hard to judge as I had to run the sound through a stereo amp and speakers to be ale to hear it.
Mine sounded similar on my C5s but happened as the car was unlocked or a door opened. Only for a few seconds but unlikely to be an identical system.

Thank for your answer.

Ofc the pum should do some noise but I find the noise to loud. But maybe it's me cause I never had a french car and maybe this is normal :) Hope it is :)

On my 1.6 BlueHdi there is no electric fuel pump so there's no pump noise.

@joaocpereira If you you have a fuel primer bulb in the engine bay like the one in the picture then you do not not have an electric pump in the fuel tank either. So it cannot be the source of your noise.

However
If the 1.6 is also a BlueHdi then the noise may be the pump for the Adblue priming itself.

Yeah I don't have that bulb.
But is normal for the adblue do this noise? Also sometimes like a 'squirt'? :lol:
