My Ride: 325ci 2001
whistling noise when starting

2001 , 325ci 5spd.208k, 33mpg, I love this ride...9th BMW
This just started.
High pitched whistle when cold engine started.
Goes away after engine warms up.
Both intake boots new, icv cleaned, disa cleaned and inspected.Both idlers and tensioners replaced.
I looked for torn or ripped hoses , nothing found.
Any ideas?
