Petrol pump? Or could be the ECU whining, mine does it sometimes.

My Clio does this frequently as well, possibly the petrol/water pump. Always done it since I had the car.

it the climate control fan above your head they start getting noisy after a while vert common do a search, but they are dead easy to change if it really gets on your t!ts

put your thumb over the holes next to the interior light to be totally sure if it stops or reduces in volume then your know

Ive got a 172 cup, and it does it all the time when the ignition is on prior to starting. God knows what it is as I havent got climate control (excluding windows) ;-)
