204ps DPF Pressure VCDS

It's in the "Advanced Measurement Values".
Perhaps "IDE07744 Particle filter: air pressure sensor 1 bank 1: raw value"
It's fairly simple conversion : mbar = hPa
What's your problem?

Hi.
Long story. Split Intercooler hose, then van tried to do a burn and couldn't, then went into LIMP mode with 2 faults.
Soot level too high and EGT sensor.
Cleaned the sensor and that fault has gone.
VCDS SCAN.

Trying to work out if the Pressure Sensor is dodgy.
Please share engine blockmap files
1) Ignition ON - engine OFF
2) Engine running at idle
VCDS > Applications > Controller Channel Map >
Tick/fill boxes as above and click Go.
VCDS flashes screens for a moment (when finished click "Done, Go Back") and in folder C:\Ross-Tech\VCDS\Logs\.... there will be the files blockmap-01-...
Note: only VCDS HEX-V2 and VCDS HEX-NET cables have the capability to create blockmap files.
Based on the data this is quite obvious:
IDE00432 Particle filter: time since last regeneration 7360 min
IDE00436 Particle filter: kilometers since last regeneration 4172.6
Typically on this engine DPF regeneration occurs at 200-250 km intervals - thus been driven without regen 15-20 times more than normally.IDE00434 Particle filter: soot mass calculated 60 g
The soot counter maxes out at 60 grams - as normal value on this engine is 6 grams right after the regen, and 24 grams triggers the regen - thus accumulates 18 grams during before the regen happens.So the actual value (calculated) should have been somewhere at 300-400 grams.
IDE00435 Particle filter: soot mass measured -1.55 g
I believe that the measured value is actually based on measured pressure across the DPF itself and normally would expect see here values less than in the soot calculated. Normally would expect to see values from -6 to 10 grams - correspondingly with soot calculated from 6 to 24 grams.However, seeing now (long time without DPF regenerations) such a low value of soot mass measured makes me wonder if the DPF has cracked and thus not blocking/filtering the soot anymore.
IDE07744 Particle filter: air pressure sensor 1 bank 1: raw value 7.6 mbar
Also the pressure across the DPF (above) is suspiciously low for not having had DPF regenerations for such ong time. The 7.6 mbar is something to expect immediately after a DPF regeneration at your mileage.Have you checked the tailpipe - is it sooty?
Not bad, but not perfect either.
The way forward would be to recondition the DPF - either clean or replace with a new. Doing a forced DPF regen might be a risky thing to do as the DPF obviously has collected quite a bit of soot.
I'm just trying to get all the info I can. It's a work vehicle and I only have a small window to do it.
I've got some DPF cleaner, which I'll spray. Then I seen a YouTube video about changing values or telling the van its got a new DPF and then trying a Sevice Regen.
Just didn't want to do the NEW DPF when it was clogged due to the fire risk.
