Today was the first day I used my glass sunroof, and noticed that when the sunroof is fully opened at highway speeds w/o spoiler button active, the spoiler position goes up to what I thought previously was stage 3 (full downforce) with the entire spoiler visible in the rearview, but no visible space between the satellite receiver and the spoiler while looking back through the rearview mirror. I thought the stage 2 position was so low that the spoiler essentially was not visible in the rearview. Well, I then hit the spoiler button and it popped up a few more inches, with a gap now visible between the spoiler and the sat receiver. So now I'm confused...is this intentional, and is there a difference in stage 2 and 3 positions based on the sunroof position or is my spoiler malfunctioning? Obviously I can't take pics of this without a passenger in the car, the spoiler comes down when I drop speeds so I can't bring it to a stop in full up position w/ the sunroof fully open. What are other people's experience w this? Thanks.

From the Service Information Technik - 911 Turbo - Turbo S document:

"The variable aerodynamics of the 911 Turbo models offer further adaptability in
addition to the functions and advantages described here. If the slide/tilt roof option
changes the aerodynamics when the roof is opened, the rear wing is extended higher
and tilted earlier or further in the ‘Speed’ and ‘Performance’ positions."

Mistery solved! Thanks!

It was in fact the sunroof causing the rear wing to further extend.
