Engine running at minus temperatures

Good morning together, I wanted to go to work this morning, so my Tarraco greeted me with a very rough run. The engine was running on 2 cylinders. The whole car wobbled and stuttered. After the 5 times the run normalizes something. The car is the 150ps diesel machine. I don’t know such a bad run from my other cars. Also all diesel vehicles. My Laguna has not had such problems today. How do you like that? that normal? Seat said that was not normal but not understandable either. Thanks for feedback
