Car: A3 1.6 TDI CAYC
Issue: DPF light is on but regen doesn't work and car is not in limp mode
So one day driving I got DPF light on but nothing happens. I tried to run regen while standing with VCDS and it finished intantly with "finished correctly". I turned on regen while driving and drove 30 mins with ~2500 RPM and nothing happens, light still stays on and soot mass measures & calculated keeps slowly climbing up.
VCDS version: 22.3
Particle filter blocking: active (not sure what this means)

Data from vcds:
IDE00025 Coolant temperature 90 °C
IDE00196-ENG100000 Engine oil temperature-TOIL 96 °C
IDE00432-ENG103847 Particle filter: time since last regeneration-T_WOUT_RGN 41184.30 s

Maybe someone has had similar experiene, seems that nothing works. I wonder if ash mass is too high and its time for change but then again car is working as usual, no limp mode, no faults, no nothing.
