Hallo
At first I want to apologize for my english but I try to explain best like I know.
I want to ask about Hot start problem of some VW group TDi engines.
This problem is knowing years ago but my question is :
Is better way to change all zero parameters or only some ?
For a better ilustration I attaching a picture.

I try to change all the zero parameters (yellow and red marked) and everything is OK.
But now I have some idea :
Isn´t better way to change only red marked parameters and yellow marked (which is defined in zero RPM) stay on the zero value ?
I want to ask if there isn´t posibility to engine backspin when engine is starting and starting injection value is injecting from zero rpm.
I hope you understand me because it is hard to describe it for me on english.
