Engine is E4 with a kind of particle filter without differential pressure sensor, without DPF temperature sensor, is only a lambda+temp sensor at the exit of the turbo.
ECU is making some estimations about DPF temperature, end when thinks is hot is starting the post injection to burn it.

I need to switch of the post injection because the KAT and DPF is disabled, look at pictures.
Also original file is attached.
