Most cars even my old 03 blip the throttle automatically when the ac kicks on. If I'm rolling at idle and press the comp button I can feel it lunge a tiny bit because of that. I don't imagine the software breaks maybe it never had it and you only just noticed. But I don't think it'll turn off. Try to see what happens with it rolling at idle with the ac button off then press it on. Also that's a really nice blue.
