You may want one done
after the temp and pressure sensor and forced regen has been done
and the car has been checked for dpf back pressure and it is clear ether unblocked mechanically or chemically
if the problem keeps happening the injectors are most likely at fault
over fueling during and after a regen not operating correctly crashing the regen
maybe worth getting them to check it out or get it done independently mate.
i am strongly debating removing the EGR and the DPF now its one crap system.
