As I said in one of my posts, I had this happen in a '72 W115 220, where the evaprator would ice up, accompanied by blockage of airflow. Then it would dump about a quart or more of watr if I shut off the car and let it defrost for awhile.
On my 240D, there's no reduction in airflow through the evaporator or ducts, and no dumping of massive quantities of melt-water after shutoff. Just a repeating pattern of gradual loss of pressure differential in the system, sufficient to reduce, then eliminate cooling, until after the system is turned of for about 30 minutes.

Happy Motoring, Mark
