I had a chance to listen to the noise my wife was talking about. When I fired it up this morning the car had a noise that I can only liken to having a Harrier Jump Jet under the hood. The noise is coming from the back of the engine and it was a LOUD air leak noise. So I'm thinking that yes, it is the secondary air pump and it's leaking. I could not see any damage or anything.

Looks like a good reason to go see my local friendly Audi dealer and exercise the CPO.

Thanks for everyone's suggestions.

Every time I start up I hear that jet engine whine for a few seconds and then it gone. I just thought of it as something normal. Anyway it has not been a problem up to now.

My old 01 Tip A6 did the same thing, so I am guessing that this is normal...
