DPF level.increases during Regen

[Jules13]

Hi again.

Yet again the DPF is playing up.
It drives normally, no error codes stored, no EML and DPF filling at normal rate.
During a regeneration, the fill level goes down as usual, but suddenly stops and starts shooting back up to almost full, then goes down a bit before Regen stops as system thinks it's run for long enough. Done this twice now. I'm about to change the DPF sensor as it occasionally throws a fault code about perimeters being outside of range.
Any ideas?
Running an Autel Maxi AP200 app so that's how I see info.

Have you checked both pipes coming from pressure sensor for blockages. The fill level is determined by the pressure.

Pipes clear, but I've changed the sensor now and it seems to have sorted the problem.
