Engine Bay Noise - 2022 RAM Laramie - 3300 Miles

I am opening a can of worms here, but I will ask anyway.

I just noticed yesterday a new noise that seems to originate from directly behind the steering wheel.

I can only best describe this noise as identical to the sound a washing machine would make when evacuating water from the tub and starting that final spin cycle.

Almost like a suction/slight gurgle sound.

It's present at idle and during driving with zero change in pitch or intensity or anything.

I have looked over everything twice and can find nothing.

I've had 4 CTD, but this is the first one Ive had (for obvious reasons) that wasn't entirely deleted before the first Regen ever took place.

Regen was taking place and currently still is.

Does Regen make any audible sound?

Thoughts from anyone on where to look?

One possibility that comes to mind would be the brake boost line.

See the link below.

I would take a wooden dowel or stethoscope and check that line and the surrounding area to try and locate it.

That will be what I do to see if I can locate it.

Everything seems good, though.

In this thread you tagged, it's very strange, as I installed these emf bushings just the other day, like the OP in your share.

It may be a coincidence, but very interesting to check out!
