ood morning all  

Bit of a strange one , now the mornings are getting cold 7 degrees here I have noticed if I rev my car even stationary after a 5 min warm up I can hear a noise Luke a quiet vacuum cleaner. The noise goes away when the car is warm. The turbo pulls like it should and no extra smoke or rough running etc (i don't put the engine under strain when still cold)

I'm just wondering if this is like a built in technology to by pass the turbo when starting from cold or a secondary air injection set up etc ? 

When starting the car on a warm day I don't get it , have heard it a couple of random cold days.

The noise isn't a high pitched siren etc more like there is a small quiet vacuum cleaner.

I can't help, I'm afraid.
But it might help the next person along if you could say which engine you have in the car

Should clarify it's not the sucking sound of the vaccum but the motor sound of a vaccum cleaner

Does the sound change with the engine RPM?

Was just hoping a couple other folk had it and it was down to some fancy thermal shenanigans
