You need to get a pressure test on cooling system which should show any external leaks . If that doesn't show fault , the next step would be a block test .

My 1.8 petrol insignia 2013 keeps having code 3 coming up .
This happens if it’s cold or hot been used or not etc.
Error book says relates to cooling but my coolant is at full mark and has never moved in all the time I have had it. This has been happening for about a month now.
I don’t feel any issues with the car nor see any leaks etc
Any ideas?
