I live in Phoenix, so yeah, this is a problem for me...I purchased my 530i in March of this year when it was considerably cooler than it is currently. About a month ago I noticed the same behavior regarding throttle input and air volume. When left for a couple hours in the sun the car cannot blow cold air.

Immediately after starting the ac will produce a high volume of air, but it is not very cold. Then when driving as soon as you accelerate the volume of air stops. Lift off the gas and it slowly will build up again. Come to a stop and it will produce a high volume again, but as soon as you accelerate it repeats the process.

Does not behave like this when it is covered or in a garage though, but I still think the air is not very cold, especially compared to my A6.

Currently at my dealership to have them look at it... will let you know what they say.

Not my first issue with this car unfortunately.
