weird noise on cold start

[BIMMAMAN]

Hey,

Just wandering if any of you guys with e46 BMW's have had a weird noise when you start the car in cold weather (usually around or below -10 deg celsius).
The noise comes from the center console inside the car and sounds like a fan/belt rubbing against something. It lasts for about 30 seconds or so and then stops. It is pretty consistent.

I went to BMW and they could not simulate the noise cause the car had already been warmed up. The bmw service guy said that it probably is the secondary air pump? But my question is wouldn't bmw fix a noise like this. Maybe its just my car?

Anyways if anyone knows about this would appreciate some input.

Thanks,

my car also makes a noise as if i was trying to start the car again when it was already on. by the time i get out of the car it's already stopped.

It's probably a combination of cold start procedures the car goes through to minimize emissions on cold start up.

Its normal guys, i hear the same sound on my old E36.

Yeah, I don't get how BMW can igonre a noise and just say that, the noise is basic, it is quite loud althought doesnt last that long. There has got to be something they have done to prevent it if they know it occurs in all cars, consistently. I guess I will just have to live with it, unless someone knows exactly what it is and I point it out to the warranty guys.

Thanks,
