Toyota Dyna 2008 - DPF burn off every 300 miles #

Hi

This Toyota has been needing a DPF burn off about every 300 miles or it will go into limp mode.

The main agent has been looking at it and has replaced the the DPF and the DPF sensor but with no luck, and now it has landed at my door.

I haven't had much of a chance to look at it yet, this is more of a fishing trip!

I have scanned it with no codes, checked for vacuum leaks with Smoke-Pro, checked for fuel contamination and am not sure where to go from here.

From my understanding the need to do a burn off is when the DPF has restricted flow and the ECU forces a burn of. However, this vehicle does not seem to have symptoms of a sooty/smokey exhaust which would cause 'dirty' running.

Any help would be great, I apologies for the lack of info at this point.

Regards

Simon

Sounds like the customer needs educating on how to drive a dpf equiped car, sounds like it's probably only doing short journeys?? (never getting the chance to regenerate)
You'll never see any signs of smokey sooty exhaust as it's trapped by the dpf, that's it's job.
Any idea what kind of ecu is fitted, a DPFoff solution might be better?

Chris.

I don,t know much about New Zealands roads/ traffic or its speed limits etc.
But i do know getting a DPF to regen in London is pretty well impossible.

propably denso ecu , not much to help without seeing the car. Why dealer replaced dpf and sensor? What symptoms was there before? No fault codes what about parameters ? Ash cumulation , p[ressore diferential anything . Definitely more info.

also how do yopu know is in regeneration mode?
A lots of white smoke when it worms it up? Some of the systems they check dpf every 200 miles? Very inetersted thing . Keep posting .
