Technical Blue smoke on DPF firing.

[GrandeGuy]

No oil usage but clouds of blue when the DPF fires.
It's done it twice now. On Saturday driving alone doing 70 all of a sudden clouds of blue out the back, pulled it over cooling fan was running and exhaust note changed whilst kicking excess heat out. Set back off and fine?
Only when DPF fires.
And EGR is mapped out, so not even gonna start cleaning that.
Any idea's?

Blue smoke is normally oil mixed in with the fuel, i had it a few times cleaned the common rail and bits of the injectors and it cleared it
