BOOO Problem came back - for a split second just as im getting down to quarter of a tank

I always drive with quarter tank normally, so the difference was i had a fullt ank.
It cleared after i shut down for 2-3 minutes and was fine after that.

Im now suspecting fuel supply Or lack of dpf regen

How would i check regen?

Fuel filter on order to replace.

archoil ar6400 diesel treatment going in next.
