New ST Puma Performance whistle

[HRF1T2020]

Hi 

Not sure if my brand new ST is normal or not 

When starting the car from cold or it’s been parked for awhile I have noticed a whistling noise sometimes prominant (with window down) from under the bonnet.

 

This seems to happen in the low revs 1-2k with car parked and when reversing or manoeuvring etc, the whistle seems to go when I’ve travelled and the car has gotten warm

 

Any ideas is it the car sucking air in or normal sound for the turbo etc 

 

Emailed local dealership where purchased to book it in for inspection, after next week as going away In it next week

 

Car drives perfectly no issues at all love it

It's probably a slightly loose boost hose

As typical it didn't do it this morning and will probably not when it goes in

If it is that is it OK to drive as going up north of country for a week next week 

Dealership got it in Monday AM can tell tech what's happening then, they said they'd have it up and check the hoses etc but will say what you've suggested.

So made a couple recordings

Like I say it's OK after a journey and this morning didn't do it but thus lunchtime it is

So back from dealership and they checked car over and road tested it and everything is fine

They also say you can get a whistle from turbo on low revs as recordings

 

Happy now and worth checking as new car and I have no reference to compare

 

Hope this post helps anyone else going forward
