The particle filter should generally regenerate each oil change and this can be done through the software of the diagnostic equipment or the vehicle is regenerated after traveling without interruption between 20 and 40 km on the road. In addition, to avoid this filter, it is necessary that the oil that is changed complies with the manufacturer's specifications, since it must be low in ashes. On the other hand, Code 84 is turned on because the oil change notice has to be restored on the board or display. It can also be done with the scanner or many cases can be done manually. I leave you a league to check if you can do it yourself.
