Mazda CX3 DPF problem

Hi
I have Mazda CX3 1.5L diesel
One defective injector is replace and calibrated injectors.
DPF is Cleaned using Diagnostic tool
It take nearly 1hrs to complete the process.
After cleaning that heavy smoke get normal and no faults are shown, but after few mins again heavy smoke is came. So I repeated cleaning process
When done after few mins driving same thing is happen.
Any idea to fix the problem
Thanks

Forced regeneration of a diesel particulate filter is a service item, once there is already a fault with it it’s not always effective, for a lot of manufacturers they only have a 120,000 life cycle anyway.

Is your complaint that it keeps entering entering Regeneration cycles when driving? Sure it’s not just coaling

Yes I did regeneration many times.
The longest time I can drive in normal condition is 15mins. When I change gear position to (P) it automatically engage regeneration.
After 15mins it always smoking while driving

How do you it’s undergoing a Regeneration, the fluid for the DPF Regeneration is not endless so constant Regeneration is not possible.

Hello, i do not know much about Mazda DPF Systems but i had many experiences with Mitsubishi DPF Systems and customers who buy the wrong Car.
tell me if i'm wrong but i think Mazda had no additiv like Eloys and no AdBlue. how much oil dillution has the car from oilchange to oilchange or earlier. if the System constantly in mood to regenerate the DPF on ist own i would check the difference pressure sensor, EGT 1, EGT 2 and so on. the EGT have hi priority for the regeneration cycle, check them to
plausibility to each other not to interruption or something.

This is data streaming show but no DTCs code

have you checkt oil dillution?
log the EGT while driving, mostly there is no DTC but the Sensor's may have faulty value's, caused from bad cable or connection's
another possibility ist the differential pressure Sensor could also give faulty value's caused by brocken or blocked hoses to the DPF
