At 3000 revs 27 mbar of pressure difference and 1.03 G/L of soot

I guess from that the DPF is good and there is nothing more to do for now than watch carefully the soot and pressure readings and see what happens. Would you agree ?
Nothing wrong with those numbers. I wouldn't bother cleaning it.

In the diagnostics, you'll find information about the average distance covered between regens, and the distance since the last regen. Leave it a few weeks, then take a look at those. Providing that you're having no other problems, the pressures stay something like that, and it's not regenning every few dozen miles, you're good.
