I have a '02 996 C4S. It is ordinarily garaged and kept out of the wet whenever possible which is most of the time. I have noticed if it is left out in cold damp conditions for as little as an afternoon and evening that the warning display illuminates for the spoiler function and the spoiler either doesn't function automatically when it should or it raises and stays there. After being returned to its garage (warmed up to dry) overnight it returns to normal working order without attention.
Does anyone have similar experience and/or knowledge of how to prevent it occurring short of leaving it garaged!
