If you are having cold wather, you can check this by starting the car and checking underneath for any exhaust vapor.

Well did you trade in the old sound? I want to see pics!

You mean you can hear air escaping (as from an air compressor)?

First time I drove my new M2 Wintersports on wet roads, I thought I blew my turbos. Apparently, it seems to be a result of the siping on winter tires and the noise they make when they "open" up under acceleration on wet roads. Just a thought.

I hear the same sound(s) on our S4 and VR6 -- only with the winter tires...
