Skoda Octavia 1.6 TDI 2010 (77 kW) - Engine Temperature Starting Issues (20, 40, 50, 60, 80, 90)

And you replaced the temperature sensor ?. It is possible that the temperature sensor in these limits has a break and the resistance is interrupted as it was completely disconnected or gives too high or too low temperature, where in fact it is different than that given by the sensor itself. (Check in the parameters the temperature value in the degree data when the car refuses to start.)

Wait.
The first time you write that a cold 15 degrees smoke and 28 degrees did not start the engine, but again you write that a cold 15 degrees did not start the engine.
Honestly, it's hard to say, because the engine does not smoke cold, it will warm up, or vice versa, and you wrote here that once it smokes and once it does not, I suspect that the engine temperature has nothing to do and probably the fuel dose valve hangs, and that the problem occurs under such temperature and in circumstances it rarely happens.
In this case, it is worth checking the injector overflows or at least checking the correction, whether it does not deviate from the norm.

Quote:

Cold engine 15 degrees Celsius engine preheats the sensor to 28 degrees Celsius does not continue to heat the sensor to 50/60/70/80/90 degrees but the cold engine around 15 degrees C and does not smoke.

As I understood correctly from this description, a cold engine in 15 degrees fires and heats the sensor to 28 degrees and does not fire, and further heating of this sensor above that you gave fires, except that in what last sentence you wrote that again in 15 deg. does not fire, since you wrote earlier that it fires. (I took into account the first and last sentence)
On the other hand, I am surprised that heating the temperature sensor separately and its disassembly to heat the sensor wanting to check, and this is not done and times are over. Because the sensor has many ways of reading by the controller and should not be unscrewed from the engine, this is the computer.
Because the controller has such features that by unscrewing the temperature sensor from the engine, it does not match the original state of the engine temperature or the lack of ground connection with the sensor and heating one of them separately, you also distort the controller and the controller does not know what to do in a given thing.

I mention that each car is different and each has a different starting dose.
I had a similar situation in my car for a long time, where from the same sensor the value on the clocks showed good, but already to the controller, however, distorted and although the sensor had two pins, one pin was responsible for indicating the temperature on the clocks, the other pin on the controller, and the whole sensor screwed to the head is a mass.

This is not strange enough, it is strange only in the way of checking and simulating, because the sensor should not be disassembled if it is not damaged, and if damaged, the computer catches errors or shows a value other than it should.
In my car I also tried to combine with these sensors, and this is a completely different solution, because like the sensor looks ordinary, but it works differently than normal. (Buying a new sensor has solved my problem, the fact does not belong to cheap such sensors, but I do not know how you with the cause).

I already have enough of your nonsense. As usual, you speak on topics you have no idea and make up your own theories. The sensor is a normal NTC thermistor. Warning.
