I noticed that it regenerates even on short trips. From 38g to 29g. After 5 days I made a 30 km trip outside the city. It went into mode 3 and the DPF reached 600-700 C, and the percentage of ash dropped to 1-2 grams. The whole process took place in 10 km. The dashboard light did not come on during the entire regeneration process. Interestingly, after another 40km outside the city, the ash level reached 10-11g. One more thing, I think the maximum level of 60g entered in the PID is wrong. From what I know, it can accumulate 80-100 g. ----- T31 2011 Diesel 84.000.km manualnondisclosed_email@example.com (bogdangepe)Tue, 29 Nov 2022 16:02:15 +0000 Re: Some DPF Pids for OBDii Scannerhttps://baustralianxtrail.runboard.com/p2099226,from=rss#post2099226https://baustralianxtrail.runboard.com/p2099226,from=rss#post2099226Not sure if you can force a forced regen with consumer scan tools. I think you need the nissan software. Also consider that a forced regen is something else than the regular regen. You have to change the oil after the forced regen. Knowing how to reliably trigger a regular regen would be very interesting. I use a cheap ELM adapter and the PIIDs.

I created an additional PID entry then exported it to csv, updated the csv to reflect the values earlier in this thread and then imported those (to save typing them all manually in the app). The additional PIDs are there but when I graph them and run a scan the results aren't very useful. The ODBII wifi ELM327 Adapter I have is able to communicate to read and clear codes. Are some PIDs available depending on what adapter is used? (none of the other DPF related codes in the app sow any data either) Main goal is to find an inexpensive way for forcing a regen and getting more information to convince me if the DPF is at fault or what the problem is. I am considering getting a better scan tool that already has the force DPF regen functions on it. What other information can I provide here to help get an answer to TorquePro setup?

Since my last post I've had a few successful cycles, one to 0 and one to 4g so it seems everything is working okay and those weird cycles aren't too much of a concern just yet. Recently I've started using a diesel additive that's supposed to affect the cetane rating of the fuel and as such it supposedly helps the DPF with burn off and a bunch of other things. I'm not sure if the claims are backed with proof but it wasn't that expensive and worth a try. nondisclosed_email@example.com (lonepolarbear)Fri, 14 May 2021 08:42:28 +0000 Re: Some DPF Pids for OBDii Scannerhttps://baustralianxtrail.runboard.com/p2098416,from=rss#post2098416https://baustralianxtrail.runboard.com/p2098416,from=rss#post2098416Will be interesting to see as i presume unless it gets down to mode 1 then it is probably classed as a failed regen and the failed regen count will be incremented.

Basically there so much soot that driving it like you stole it will remove some of the soot, this is why the soot goes up and down a bunch in mode 4 and can sometimes passively regenerate enough that it flicks back to mode 1. I'm having an issue currently where my DPF cycles, soot hits zero and stays there a while but when it finishes the cycle it's back to 20g. Not sure if it's a bad couple cycles or indicative of a deeper issue. I'm keeping a close eye on the next few cycles. nondisclosed_email@example.com (lonepolarbear)Sat, 27 Mar 2021 21:15:26 +0000 Re: Some DPF Pids for OBDii Scannerhttps://baustralianxtrail.runboard.com/p2098358,from=rss#post2098358https://baustralianxtrail.runboard.com/p2098358,from=rss#post2098358quote:aus dan wrote: John is right. 4 = burn needed and 3 = burn in progress.

I wouldn't surprise me if this is why so many people have problems after a few years rather than blocked DPFs. The consult III doesn't even seem to display the soot mass PID only the dpf pressure diff which is almost next to useless to give you any real information. The soot mass PID is obviously there and i believe is available from consult III+ so not sure why it has to be so hidden for basic scanners.

I'm pretty sure 1 = normal, 3 = DFP burn needed, 4 = DFP burn in progress For the soot mass mine isn't starting burns till it is over 30+ grams, so I guess keep an eye on it and work out what your normal range is. For the Temps I typically see 200c to 300c when it is running normally (depends on the speed and load on the engine) and around 400c to 600c+ when it is doing a burn. The mode is wrong. 1 is normal and 3 in DPF burn in progress. 4 seems to be a bit strange as it goes into 4 after about 12.5 grams of soot. As mine doesn't ever get down to 0 soot it tends to be in mode 4 most of the time until a burn off which may take it down to around 10 grams. I guess either way it is easy to see a burn off, mode 3 and exhaust temp up around 600.

How do you know a regen is taking place? Soot Mass in gram: Shows the soot obviously. Regen should start at about 25mg DPF Mode: 1 is normal? And the higher the number the more clogged the DPF is? Or does a higher number show the regen status or that it's active? Temps: Which values show that the EGR is doing its job and that a regen started? DPF Exhaust Flow Rate: Where should this value be at when the DPF is healthy? And where is it when its clogged?

Something that triggered the regen at lower revs or during normal driving would be better than what we currently have. Looking at the engine during normal regen it only needs over 2k revs and high temp exhaust gas - this could be done without needing an oil change. I don't actually bother with forced regens as mine always failed after 40mins. This to me showed that the regen had actually worked but the soot mass had not gone back down to below the required level to trigger a successful regen. What i tend to do is just do a dpf reset which tells the car it has a new DPF. I then go for a drive and the DPF soot value gradually creeps back up to where it was but then if needed it does a burn off like normal. I know this is supposed to cause the car to do regens at the wrong intervals but my DPF soot mass never goes back to 0 anyway. It does go down to about 10mg and the diff pressure is fine, so i know the dpf is not going to jump out of the exhaust anytime soon. To do this and a forced regen i use the Autel AP200 dongle and mobile app. It's about $100 which together with oil and filter is probably cheaper than taking it to a garage to be done. It will also show the diff press reading which is what Consult III shows. You can then compare that to the service manual. I find soot mass much better for this though and something which is really strange as it is only available using Consult III+ I believe, even though the PID is readily available.

Out of interest @J, how do you force a regen, any chance for some screenshots or something showing the process? Mine seems to be cycling fine but it's good knowledge to have in case. I actually noticed that currently my DPF Mode didn't flick to mode 4 until it hit 24g. I need to give it a run and let it cycle late this week/this weekend and I should be able to plot a new graph. Since that first graph I've done a change from the oil that was in it (Castrol Magnatec crap) for Penrite C4, had to replace a pipe for the intercooler piping cause it cracked and I had boost leaks and installed a Provent 200 with a new oil free air filter.nondisclosed_email@example.com (lonepolarbear)Tue, 22 Sep 2020 08:56:41 +0000 Re: Some DPF Pids for OBDii Scannerhttps://baustralianxtrail.runboard.com/p2097976,from=rss#post2097976https://baustralianxtrail.runboard.com/p2097976,from=rss#post2097976I think more info and a manual regen button (like the hilux now has) would have been a better move. nondisclosed_email@example.com (aus dan)Tue, 22 Sep 2020 07:02:08 +0000 Re: Some DPF Pids for OBDii Scannerhttps://baustralianxtrail.runboard.com/p2097973,from=rss#post2097973https://baustralianxtrail.runboard.com/p2097973,from=rss#post2097973Now that I agree with.

My DPF never goes down to 0. I've had it go back to about 9 once but never got it anywhere near 0. I think my DPF being after market is mismatched to the DPF sensor and eventually causes the DPF/Mil lights to come on. Why Nissan didn't provide a way to access this information easily is beyond me - it would have saved so many people unnecessary pain and trips to the garage. It's also strange that the ECU is easily capable of providing this information but most scan tools including the Consult III, GSCAN2 only show dpf pressure differential not soot mass and that is far harder in my mind to monitor what is going on.

My dpf does make it to 0 during the cycle, once the cycle finishes it usually goes back to 3-5 but I have had it sit as low as 0 for a fair while after the cycle in the past when I was doing a trip to Rockhampton. Dpf mode sits on 1 a lot of the time and seems to flick between 1 and 4 in occasions when there's a bit of soot but it's not sure if it wants to run a cycle, usually from around 12g or so until it does the cycle. This was a cycle I caught back in June and it only hit as low as 7ish and came up to 9ish after the cycle. I think this was before I moved to c4 oil and well before I found a vacuum leak and fixed that. nondisclosed_email@example.com (lonepolarbear)Sat, 12 Sep 2020 20:19:35 +0000 Re: Re:https://baustralianxtrail.runboard.com/p2097815,from=rss#post2097815https://baustralianxtrail.runboard.com/p2097815,from=rss#post2097815Sorry i hadn't seen you reply - not been using the board much as it has gone pretty much to sleep for the T31 also i am just nursing mine until it eventually dies. It's got 300k on the clock so not sure how long these engines are good for. I presume you got all these PIDs working? I would be interested in knowing whether your DPF mode stays at 1 much of the time and what your SPF soot mass goes to once a normal regen has been performed. I changed my DPF a few years ago for an aftermarket one and i think there is a mismatch with the car. Even after a full regen i can never get the soot mass below about 10gms. This does trigger the dpf mode to hit 1 but then changes back to 4 once it goes beyond about 12.5 gms. I think the soot mass not going long enough triggers a failed regen and the light and mil lights do come on every 6months or so. I just reset them and the dpf (which i know your not supposed to) and then i am ok again for another 6 months. I know the DPF is regenerating just not down to the lowest it can go.
