Dispatch 1.6 2015 - Filter Clogging Problem - Help needed

Please can someone advise - I recently purchased this van from my workplace, so I know the history, it's done 250k miles, There was a problem with an engine fault and the message "Danger of filter clogging" and into limp mode with the radiator fan always coming on. The company had it cleaned and the message went, it flew through an MOT and then 2 weeks later bang, the same thing happened. They again had it cleaned and same happened. So they decided to sell it. I purchased it, took it to a garage who cleaned the egf? Valve, replaced the fan sensor. Cleaned the DPF again and it was ok for 3 days, then the engine management light came on, then the same problem occurred.
Please can someone advise me as I have been told the problem is that although the people who cleaned them can remove fault messages even if the filters are cleaned/replaced the messages will keep coming back until I get someone with the ability to tell the computer that the DPF is CLean or Replaced. Sorry to sound like a dummy but I'm stuck with a van I cannot drive.
Thanks in advance.

The DPF needs to be removed from vehicle and cleaned of all soot if this is done on van through regen and its been heavily clogged it might still be 70% full......

If cleaning off the van was done It could be a software problem and not recognising the instruction or as you a say needing one  more specific OBD reader to Citroen....
Could maybe be a faulty sensor either at the front or the rear of the DPF registering incorrect pressure reading and tripping warning ......
In which case a proper full OBD scan/reading and not just a generic one..........

Also is it one of those PSA Vehicles that needs the FAP/DPF fluid refilled

Thank you very much for the reply. I think the dpf is clean but the garage only had the generic lights out info gone computer and I need to take it to a main dealer. Can you advise if it's ok to travel in limp mode with the fan constantly on.

Driving it would be very much your decision............
1.If DPF is clear and in Limp mode it sounds as though it's not doing job properly..............
2. if it's FAP (DPF) Fluid bottle is empty it's definitely Clogging at a faster rate and bottle needs refilling and reset.............

The safest option is obviously have it trailered/recovered there ...........

If the Dpf is fully blocked I would  have thought engine wouldn't run ( Had a Cat do that on a petrol engine  vehicle before) ........
But if it's restricting exhaust flow greatly  engine damage could follow.....
Hence limpe mode..........

I Dear Say the question is "How longs a bit of string " .............

I'm Sorry I can't really answer your question .... Don't know what I'd do..........
