Just had my software updated a couple weeks ago to version 15.2. I don't know if it's software change related, but my auto climate control system isn't functioning properly. Not much airflow on auto, and it's getting pretty stuffy in the car. Anyone else had this problem?

 

Yes, but not in winter. In summer, when it is humid or raining, the evaporator freezes in our car, completely shutting off all airflow to the cabin-- fan at any speed, temperature hot or cold, direction anywhere.

 

I have just had 15.2 and Auto mode seems to be MUCH more affective than previously - in fact it now works pretty much like my 3 series used to. The airflow starts very low until the engine warms up and then it will increase it until the cabin has reached the desired temp then it backs it off again.

Before I had 15.2 the airflow was always constant!

 

Did you check the setting in iDrive that controls how agressively the climate control system works? There are three settings, one is low, one is normal, and one is high. Maybe yours is set to low by mistake?

 

Yep, checked the setting and tried both high and med but the system still isn't working. I can turn both dials down to the minimum, and the airflow doesn't increase a lot, and there doesn't appear to be any AC. When I hit the Max button, the AC kicks in full steam, so AC is working. Something's not right.

 

Yeah, it does sound like something's amiss...
