Sporadic tugs on road after change of particle filter

Good morning, after changing the particle filter, I will have about 800k and the EGR valve, some thyns have appeared from time to time, I have taken the car to the workshop and after putting the computer has detected the P0234 failure, the turbo tubes have been checked and they do not appreciate that they are wrong or they are heard blows or nothing strange, the fault has been erased but at a few km, they have appeared again. They are removed after about 5 or 7 pulls, the car is going great, without any fault signal appearing in the control box. All filters and oil were changed 10,000km and the additive for the departicula filter 30,000km, since every 60,000 they fill it
awaiting your opinions, I thank you in advance.
