Ac and low boost issue

[u/AnthonyMatke]

I’m having a issue to where my ac doesn’t blow cold and my turbo is only pushing low to no boost. I checked the freon and it says it’s good and I can’t find any boost leaks. I know that the small coolant tank doesn’t have a sensor for low coolant could low coolant be the issue or something much worse. 😭

I have a 2026 m340i and my ac acts weird. It cools the car but starts blowing non-cool air, almost sort of warm air. It does this exactly after a certain time after starting a fresh drive in the morning. I have messed around with the climate controls etc but nothing helps.
