Hello everyone ,i'm curious about a sound which my punto evo 2010 makes whenever i open the driver's door after a long time beeing parked. It's strange and it looks like an airplane beeing landed from ground or something like this , it continues about 2-3 seconds and stops and it comes from engine or near it. Does anyone knows something about it?

Is it a dualogic (semi-automatic) version in which case it is the pump priming the system up to 40psi.

Thank you, it is indeed a dualogic.
