For those with the ac issue take it to the dealer. I did NOT have any software or hardware faults but got lucky that the tech working on an m5 next to my car had the same problem and recreated it. They let it run with a thermometer and saw the changes.. They contacted bmw to confirm and new parts arrived about 2 weeks later( ordered from Germany , its multiple parts so make sure they don't just order a compressor, there's some sort of valve too). The parts are Being installed now. Be vigilant; Let them keep the car overnight if needed. I know the "m" dealers are supposed to be the same as the regular dealers but if you have the M dealer go there. I find they're more intelligent (they even fixed my keys which the dealer I got the car from said there as no issue) and have fixed all my issues without hiccup. Not all dealerships are made the same

I had this same problem but it went away once I switched it back into the normal driving mode

Generally the A/C works perfectly, often starting to blow cold air before I even leave my driveway. However, on occasion it simply blows hot air (likely just ambient air temp). Sometimes this persists for several drives. Other times, 5, 10, even 15 minutes into the drive it starts blowing cold air with no intervention on my part.

I've tried searching on here for someone with my specific issue and I haven't seen anything. I'd love for this to be user error, but I think I've tried everything! I've read about setting the vent temperature in the menu and that's not my issue. I have taken it to the dealer twice, and both times the A/C started working as I left to drop it off for the service appointment. Once, I started driving to the dealer when the problem was present only to have it start working as I exited the highway near the dealer.

The dealer claims that there's nothing they can do unless the "see the problem". They checked for errors reported by the system and can't find any evidence of an issue. My fear is even if I take the car to them when it's exhibiting the problem, it will begin working before they can troubleshoot it.

I consider myself to be a patient person with regard to a lot of the glitches with the car and have hesitated to post about this until I exhausted other options. At this point I'm getting REALLY impatient. I've resorted to leaving VMs for my service advisor every time it doesn't work in a passive aggressive attempt to get him to pay attention. When it's working it's perfect, but it's like a roll of the dice every time I get in the car. Considering the $$$ spent on this thing, I just find this whole think unacceptable, but I think I might not be making enough of a stink with the dealer.

Thoughts?

What you're experiencing is because the car is a mild hybrid it shutting off and shutting the system down resulting in the air temperature being warmer until you move again in the air conditioning works
