I'm sure when I unlock my car then when I open the drivers door I hear the fuel pump prime

sounds exactly the same.
anyone had this before ?
A little while back the car locked itself with my key in the ignition ( not turned on ) and somebody said check the door because if it is opened it shouldnt lock itself but the interior light comes on when I open the door as does the paddle light.
If i close the door and open it again the fuel pump doesn't prime again. More annoying than anything at the moment.
Any tips appreceiated I am useless with electrics.
Mk4 Golf Gti btw
