Hello all! I’m new to this forum and thought I’d join for some help.

This noise has been happening for about 4-5 days now. It’s a very loud whistle that comes from the engine bay on every cold start. It goes away once the RPMs drop. I had to cut the video into 2 since the file was to big. You can hear it stop once the RPMs lower. There’s also alot more whistling when driving the vehicle.

Any help would be much appreciated! Thanks.

Sounds like the secondary air pump. Normal under cold start.
