Aircon will always power down when stop-start kicks in. The system will engage recirculation only to retain that colder air.Simmo wrote: ↑Wed Aug 14, 2019 10:34 pm This is the first car I've owned with the start/stop function.
It seems to work perfectly well, whether the engine temperature is cold or hot. Not noticed it cutting out before coming to a stop like some have but I am trying to remember to switch it off before driving off after starting engine for the first time.
It would be beneficially to have a setting to permanently switch it off as it doesn't benefit my driving in anyway whatsoever. Aircon tends to power down when engine auto stop is engaged and I'm convinced this system is bad for the battery and starter motor, let alone wear and tear on cold start/stops.
Manufacturers have put in more robust starter motors and batteries designed for stop-start systems. The first cold start is the one with measurable engine wear - the one with no oil circulation. After that, even if the engine isn't warmed through, wear will be minimal with stop-start restarts, as there will be oil between the moving parts.
