A3 1.6 TDI CAYC DPF light is on but regen doesn't work (no limp mode)
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:

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.

Ash over 40g, it won’t regen. The book says if you cheat the figures “warning, vehicle may burn down”. We would take the DPF off and send it to DPF Clean Team in Hinckley. When it is refitted, we fit and calibrate a new GENUINE only pressure sensor and then carry out a forced regen or service regen if the manure provides it.
