Hey I recently got a Mazda 3 about two weeks ago. On the first day of having it a flashing DPF light came in the dashboard. Since then I’ve tried various things to try and get it off none of its worked. Even took it to a Mazda dealer and they erased the fault code and reset the parameters. Lasted 3 days and it’s back on. The car is also going into regen every 18 miles. And takes 10 miles for it stop. Im not sure if anyone would have any sort of idea of what’s going wrong?
side note: it is a 2017 1.5 Mazda it has 49k
