At how many degrees you have pre-glow?
I need the exact value of the temperature of coolant! You can find out by connecting a potentiometer (4.7 k) for temperature sensor...

It have 4 sensors ( ambient, intake air, fuel, colorant), if any show more than -9 C, no pre-glow! and car can't normaly start.

I think you totally wrong. The time of pre-heating depends only on the temperature of coolant.
And I think that there must be pre-heating to exactly 19 degrees.
