Ahh really dont have the engine code to hand sorry it doesnt actually have a fault drives fine no smoke no struggle up hills ectAntipollution fault is NOT a fault its a warning message.
Your code reader may not be giving you correct codes as handhelds rarely work well on peugeots
It would be more useful if you could describe what is actually wrong with the van is it smoky does it drive ok or struggle on hills etc what actual engine code is as different ones have different systems there are at least 20 1.6 hdi engine codes !

Engine code is part of the VIN its stamped in its on a sticker on the lower edge of dash its on the V5 its on the MOT you should be able to get it from 1 of these sources.
I have mate still doing it :/ pain in the arse only had it for a couple of weeks the centre screen wires had been cut so when I reconnected them it showed it9hx is your engine code so it should not have a DPF to worry about most likely thing is poor airflow causing the ecu to get upset give it a bit of a thrashing for a couple of miles sometimes they just need to clear the cobwebs out.
