Cayman S – 2014 Problems

Hello Together, I bought a Cayman S, BJ 2014, which now ran 10’000km. Now some “problems” have occurred, I have the full guarantee on the car and will bring it to a PZ, but maybe someone already has such a clue / can give me more detailed information. 1. Spoiler The spoiler went today into a “neutral position”, meaning that it was neither high nor properly closed. After the further drive, however, he closed himself and the problem did not occur any more. Did this ever happen before? 2. Interim maintenance Since recently in the display it seems to me that an intermediate maintenance is necessary. Is this after only 10’000km “normal”? What is done here and what would the va cost be? 3. Air conditioning that doesn’t seem to work properly anymore. Is the outside temperature > 25 degrees, it only blows warm air into the vehicle. At low outside temperatures, it cools even so much. Is probably lying on the coolant stand? Can this be queried off on the display? Thanks for further information
