Looking for advice please... RE: Turbo hose popped, blocked DPF... what came first?

I am no expert but it would seem to me that the dpf was working fine as it had its last regen105mins and 87km since the breakdown.
How does that relate to the breakdown - well before the breakdown?

Are the two soot mass values before and after regen? I am not sure why it list 60g and -0.16g?
The values are current values.

60 grams is simply calculated value based on - I guess - exhaust temperatures and fuel consumption. However, 60 grams is the maximum the data item can show, thus we actually can't tell if it is just 60 grams, or even 6000 grams. The DPF regen is triggered at 30 grams calculated, the DPF light is triggered at approx. 35 grams. Anyways, the 60 grams is just insane value after 105 mins/87 km after the claimed last DPF regen. At that point the calculated should be somewhere at 15 grams. The usual case to see 60 grams is that the engine doesn't do DPF regens at all. Also worth noting that OEM ECU won't allow DPF regens above 40 grams - won't happen unnoticed for driver.

The -0.16 grams is a kind of measured - based on differential pressure across the DPF. Normally I would expect to values -5...+10 grams. For a blocked DPF much higher - up to 30 grams.
This coupled with the fact there was no dpf warning light before the breakdown, and the dpf flush company said they have never seen one so blocked
Remap was done around 1k miles ago
I'm inclined to put blame of the blocked DPF on the remap:
  • the reported DPF values are just insane - my suspect is the DPF has been mapped out and the ECU reports whatever the remapper has programmed. Too bad the garage couldn't get full engine data.
  • 1000 miles without DPF regeneration would have accumulated 100 - 200 grams soot calculated - that would have blocked the DPF significantly.
 
Thank you for the explanation. I am still confused as to why the vehicle would record a regen at 105mins / 87 km in the history file. I had no DPF light on the van... ever. The tuning company insist that the DPF has not been messed with, only EGR.
Long and short of it would seem that when DPF is put back on van it will likely run for a while and then block dpf as root cause hasn't been rectified...
Now im thinking best to have EGR reinstated and replaced.
