I think there is a problem with F15 letting some of the engine heat come back into cabin. Even on not very hot days with A/C (or heater) OFF, I can feel there is some kind of heat in the cabin from lower section. I thought it was because I got a black BMW but I don't think it can make that much difference, at least in low 60's. I also noticed the dashboard gets extremely hot, unreasonably. Maybe dashboard doesn't get much hotter than other vehicles, but it does retain heat for a long time. My vehicles 10 years ago had hallow dash plastic (not solid/filled like BMW's) they used to get scorching hot, but they would get cool pretty fast too.
Is it possible that engine is letting some of that heat come back into cabin, coupled with weaker A/C makes it very difficult to cool the cabin?
