Ghostly noise from heating vent!

[RedM]

I've noticed during this cold spell that, until the heating warms up, I'm getting a very low, melancholic whistle from the central heating vent.

It's the sort of noise that should accompany the tumbleweed icon or that you'd make in a scary situation to scare other people. Does that make sense?

Anyone else getting this?

Oh yes very funny.

That vent could also be called the centre heating vent. Sheesh, lucky I didn't write about the hair conditioning unit!

sorry no offence meant thought it was funny myself but then Im senile

Im not sure how the vents work or where the fans are I guess its just a dry bearing somewhere?

I used to have a Ford that did this.
I think it was the bearing on the fan, but it never failed, just wailed at me until it warmed up.

My BOV does this, it's quite eerie late at night :)

It only happens when the car is cold, light throttle and just coming on boost (0-0.1 bar or so)

Maybe it's because I'm easier on the throttle when its cold, I suppose when it's hot I give it more stick so it's boosting quicker and doesn't linger around that point, when its cold, I try to keep it off boost for the first few miles.

Hmm.... that's exactly the sort of driving I'm doing when I hear it. I'm pretty sure the BOV isn't in the dead centre of the car though.
