This is my first car I've owned with a sunroof (my B5 did not have one) so I guess I'm a sunroof n00b. I've had my Avant for about a year and a half now and just recently while looking at the car from the outside, with the sunroof open, I realized that it seemed like the roof should go back more, even though the dial was turned all the way over. So I got in the car and twisted some more, and sure enough the dial gave way and the roof opened more.

Did anyone else take a long time to figure that out? And why would they do this?

I drive my B6 for over 3 years and never realized that the horrible buffetting noise would go away if I had just closed the sunroof 1 notch after turning the **** to the default fully open position.

Audi designed the B7 sunroof to not fully open by default because of the airflow/noise issue with the B6.

I'm sure dealer service departments got sick and tired of having to explain it to complaining B6 customers.

the buffeting. In fact I just got back from a 25 minute run on the freeway where I was between 55 and 80 most of the way. Only time I had it was at about 40 on an arterial, and it was only for about 2 seconds. I wonder if the Avant shape changes the effect a little or something.

i knew from the get go...my '02 jetta was the same way.

Did you have the rear windows open at all?

On my B6 sedan, the buffetting only occurred (well...was only really obnoxious) when the roof was all the way open and both rear windows were totally closed.

I used to crack one rear window a bit to make the buffetting go away.

It never occurred to me to simply close the roof a tad.

I do remember my friend complaining about his B5 being bad about that too, now that I think about it.

I tried mine but after putting a fair amount of pressure on the dial, I decided to not force it any further. I don't want to show up at my Dealer trying to explain how I broke-it.

... and said it was for buffeting and drag, both of which I notice in my Avant when the roof is open all the way (it's certainly likely that some speeds suffer from it more than others).

Dealer is Barrier in Bellevue, FWIW (I know you're local).

There should be visible painted marks showing the extra area for the dial, past the point it normally stops. If you turn the dial into that extra area (requires a little extra force, but not much) and hold it, the roof will open up more.
