2 minutes is more than enough time in severe cold.
What he said. This will be my first winter back in North Dakota with a diesel engine, but I rarely let any engine warm up for more than a minute - even at -20 degrees.
Don't the ecodiesels have the same kind of electic cabin heater that was on our old 2008 CRD to supply some warm air to the cabin when the engine was cold? The 2008 had 3 50-amp fuses for that system so I assume it supplied at least 1,200 watts to the heater.
