DPF regeneration

Hello

Recently I was trying to find out when is DPF regen happening to my car.
Via vGate vLinker MC scanner and Car Scanner pro I was surprised to find out the following:

[ECM] Soot level: 42.18g.
[ECM] Distance since last DPF regeneration: 6921 km
[ECM] Odometer: 172559 km





Do you think that driving for 6921 km (including highway driving) with no regen is normal?
What does soot level: 42.18g mean? Is it much?

The engine pulls well and has no other problems.
No warning engine lights or anything.
Actually, 2 months ago I had troubles with DPF, and car had no power at certain time, but after some days on the highway that went away.

Note: Car Scanner is not showing sufficient data with Kia Carens 1.7 CRDI profile, so I was to use another profile - for Hyundai i40 1.7 CRDI.
I am not sure if this could affect in some way the data shown from the scanner.

Any input would be appreciated.

Some updates:

Due to P242F error code "Diesel Particulate Filter Restriction - Ash Accumulation" following was done:

DPF filter replaced (not original).
DPF differential pressure sensor replaced (original).
Exhaust gas temperature replaced.
EGR checked.
Glow plugs and injectors checked.

Result was:
Error code cleared
DPF differential pressure readings were:
At idle 0 hPa and @2000 rpm - 10hPa
Soot level - 0g.

Now 800 km after repair again troubles.
DPF differential pressure readings are:
At idle 20 hPa and @2000 rpm - 150hPa
Soot level - 40g. !!!

Car is making some strange DPF regens and soot level decreases by 5-10g from time to time, but is never 0g.
Manual DPF regeneration could not be performed, I guess due to high soot level indicated.
No errors are displayed, but I wonder until when?

Anyone with similar issues?
