How accurate should a coolant temperature sensor be?
Car was left standing for 8.5 hours outside. Whole day it was temperature around negative 5°C, right before starting car instrument panel was showing -6°C, but engine coolant temperature -1°C
Sice car was standing still for so long, it should be competely cold and I assume readings should be closer...
As ususal it started quick but was jerking and misfiring right after starting for a couple of minutes.
How much this measurement difference could impact the cold start?

If your coolant was really -1 I think you would have a really serious issue
The sensor is probably not accurate enough, that would be my guess.
I dont think it is related to misfiring at all, to be honest. Maybe bad quality diesel, or glow plug relay? Did you have those issues when temps were more normal?
