whining noise on cold stat up ?????????

I have this if I have my aircon (turn the blowers on the wind screen and the AC turns on no matter what) maybe try turning that off to see if it goes away? I just assumed it was the aux belt in the cold weather
 
It's the turbo spooling up.........






Joke, mine makes a slight whiney noise but I doubt it's anything wrong as it goes away quite quick.
 
iam so glad i asked the question as i was about to take it into renault and get my a£se slapped ! thanks all ......mmmm what else can i ask mmmm
 
mine does too - had me worried at first.

I once had mine started up from cold on a ramp and you can hear the noise change when the car gets to temp from underneath.
