Hi, my F30 320i LCI aircond is quite good, i jz left the dial at 25c, doesn't take long to cool down. I do find sometimes its much colder especially if car is parked in shade...My car has 3M tints.
Btw, don't forget to "air" your car using BMW mobile app if parked in the sun, it helps a little! Another tip is, if driving under hot sun, put the blower facing upwards for a while to have the cool air above your head, keeps the heat from radiating down to your head... :smile:
