Still trying to get the car to start right in winter...
(2007 V50 2.0d)

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?
