It's happening with the block heater plugged in or not. I suspect the BH may have gone away as I don't notice much difference in warmup time in the mornings after it has been plugged.
Has never had any bio in it since I've owned it (one year) and I doubt prior either (owned by elderly gentleman).
I have seen the fuel starvation behaviour before as I had a 240d that did this if you parked it for more than a few days. But it did it at all ambient temps. Lots of cranking but no excess smoke on startup.
I am wondering about an air leak as well. But I have never seen one that magically appears at extreme low temps. The difference between how it starts at -15C and -20C is huge.

Sounds like your block heater is out. There is a world of difference in starting with and without one at those temperatures. Usually you can hear the heater sizzle as well when working. Starting at -20 C at all with no block heater is not too shabby.
Thats about 5 degrees below zero F. if -15 C is plus five F. Just to save general wear and tear at those temperatures a block heater should be working.
This is a strange winter in our part of eastern Canada this year. The ground has not even froze up yet other than a little bit through some nights. Although it was getting colder than usual when I put the dogs out the last time this evening. No snow yet except for once a month ago that melted off quickly.
