Hi all,
Within the last two weeks I've gotten this weird whistle on Cold Start. Its quite obnoxious and something new I've never heard before. It's regular, almost every time I start my car, however it goes away after one rev to 3k. I have 75k miles. Can anyone diagnose this or heard this sound before?

I'll attach the videos below

Appreciate any advice or ideas you have. Thank you
