Yet another DPF drama

[YoungEnthusiast]

Hello,

I have replaced my dpf with a brand new one.
Plugged in all the sensors and the hoses to the pressure sensor
But the light is still on so I'm starting to think the pressure sensor might be bunk as per a post from 2013 but haven't the foggiest where it is or how to actually test it.

Would love some advice or to know if there's a service manual I could pinch perhaps?

I've got a 2011 Nissan Navara D40 Rx Thai built

UPDATE: I took it for a drive to the mechanic half an hour away on the highway which seems was enough time for the DPF to consider itself cleaned and the light turned off

I have purchased an Ancel X6 and will report it's functionality none the less on a separate thread

The DPF routines in the ECU don't respond to the normal clear commands. There are two ways to clear it, hopefully the first is the only one needed.

With a workshop (eg Snapon Tools) OBD tool, select "DPF Reset" from the menu. This should get the ECU to go back to normal monitoring of the sensors.

You could try looking to see if a "Regen Required" flag has been set in the ECU too, make sure that's cleared. A new DPF won't need one!

If that fails (and with a new DPF, it shouldn't) you'll need to do a regen (available as a task on the Snapon etc device). This is a nasty process, start with a full tank of fuel, and have a new oil filter and enough oil to do a full engine flush and replacement afterwards. Expect to hear the engine screaming - it is NOT kind to the motor. This will cause the ECU to reset the DPF flag.

Thanks for your reply I had a feeling there was a secondary system hiding a DPF light reset from me

I'm taking it in for a blue slip on Monday and was gonna ask them to have a geez at it so I figure they'll have the tool to reset it, but I plan on kitting up to beable to do it all myself what tool exactly would I need so you think and are there alternatives to snap on cause those things seem to range from expensive to eye wateringly expensive

The common garden variety OBD adapter + phone app will NOT do this AFAIK (I've tried a few). Some will report the error, but won't allow you to reset the DPF routine.

I used "Snapon" simply as an example. There's a whole bunch of these available, some of which exceed the "eye watering" level and actually reach "one kidney and your first born child is enough for a deposit" level.

Any workshop tool that can talk Nissan Consult 2 ought to be able to handle yours (automatic gearbox too).

Do you think an ancel x6 would be fine for my use case seems to be within budget for me and claims DPF/all system scan

And pure curiosity, what makes these kidney and first born child scanners so much better then others?

The Ancel looks good, supposedly manages most vehicles from 1996 to present. It does specifically talk about DPF service ("numerous functions" ) so it SOUNDS good.

Feedback on a few forums seems to indicate that it's a reasonable unit with one revealing comment "works on everything including Mercedes ... a mate has one and it is his go to scanner now."

Sounds promising, but I can't guarantee it because I've not tried it myself. My local mechanic hasn't let me see his unit, so I can't say what he's got. I'm taking the bike there during the week for rego so I will try and remember to ask.

Awesome I might go for it on payday and I'll update on the forums if it's worth it or not
