Mine has also gone up at slower speeds. I know because my wife was behind me and thought I was waving to her. I did not have a clue that it was going up. I can't see the spoiler through my rear view mirror. Maybe it is also raised by rpm. Just a thought.
I could never see the spoiler on my.1. I understood that the spoiler extends higher on the.2 with SPASM--it's easily seen in the rear view mirror. Also, it doesn't extend until ~75 and closes at ~50. Watched it today and checked my speed for both operations. Also I think it does extend when high temperatures are experienced.
I only noticed this about a month ago when a friend of mine was following me to a restaurant we were to have lunch. He thought I was trying to show him how the spoiler works and I had no clue it would go up/down even at lower speed.
My spoiler goes up and down way more than just above 75 too (it's easy to see in the rear view mirror). It happens on almost any drive that I take.
In the 997, the spoiler would deploy if the engine got too hot. In sport and sport plus modes, the engine runs cooler than in normal mode. I would think that the spoiler deploying is related to the engine temperature.
This would explain why they didn't want to do a non raising ducktail lid for the 991.2 sport design...the turbo engine probably runs hotter and needs more cooling, which the wing deployment helps with.
turbos get air from the exhaust which is cooled by intercoolers
They get air from the intake (cold side) which is then cooled by the intercooler, and compressed before the air hits the engine. The exhaust gasses (hot side) are used to spin the turbine to compress the cold air. They don't get air from the exhaust which is then cooled down and injected into the engine.
