Was the freezing weather at fault? If I recall correctly, sometimes the moisture builds up enough that it will freeze the diaphragm shut and blow all the crankcase pressure out.
I did my CCV system in 2016 and I was happy to report that I didn't have any issues this weekend. We had a whole day where temps didn't get above 3 degrees F, and due to 18" of fresh powder the BMW did a lot of duty, as well as getting parked outside. It's probably about time to start thinking about doing it again.

Unfortunately, I did not have the knowledge, or was given any insight or warning about changing out the CCV system when i purchased it, which has been 3 years ago now. The freezing weather was most definitely at fault.
