2011 A4 with CVT. 1400miles

From a cold start (74 degrees in garage) I'm hearing this odd lower pitched woosh noise when I'm backing up. Almost like the car taking in a huge swallow of air.... It goes away within 20 seconds.

I parked today so I can pull forward from a cold start and see if the noise is there.

Any ideas?

This has been brought up by many other owners. It's just one of those things about the B8's. If it bothers you, just wait until the RPMs drop under 1K before moving and you won't hear that noise.

Cool, thanks. I did some googling but didn't quite find what I was looking for.

Doesn't bother me, but have never heard a car do this before.

Been told it is an old fashion air pollution control pump for the motor until it reaches a certain temperature. I think chevy gave up the air pump in the 60's. Hey go figure
