Anyway, what are the factory-fitted cold start aids into your car? Just the glowplugs? What do you think about a grid heater?

I only have glow plugs who run a few seconds before start. And around one minute after start. After that. No glow plugs anny more.

I was thinking of heating the pressure fuel line only after start up. So the expansion is equalled out with fuel use. Maybe a fuel filter heater to.

But first of all. I wil messure temp of the metal high pressure line from the rail to the fuel injector after driving a long route. Then i know how hot i may make it
