Reach out to the field rep in your area , try BMW geniuses and if no resolution send a letter to BMW corporate. The car is under warranty. Ask the dealer to try turning A/C on in a few other 240s with you in the car. Even better, just show up and ask a salesperson for a new unit test drive. Then get the service manager to sit in both cars and have that person come up with an explanation. The other way to go is trying a different dealer service department (unless you are in Tucson as there's only one there).
