Also I asked them to check if the Turbo Drain Mod had been done and if not to do it.

Any comments on the number of regen fields?

Matt & other gents,
Interesting....
I have never removed the Mass air flow sensor on mine, but it is a very easy job so will have a look at it next week.

Rob,
I am waiting for Greg’s comments on your screenshot, but my first thought is that they are a bit useless unless you know over what period of time they have clocked up ?.
Can you reset them to Zero and check again in say a months time, or at least take another set of readings in say a month or 1000 miles or whatever? and calculate the difference by subtracting today’s ?

Mike
Not sure how to reset them on the IID?
I don’t get an amber DPF light so am just curious if the field values are normal if that’s makes sense?
What is difference between demanded and successful ?
I have the famous P040D-00 (2F) so booking it into Rovertune soon to have temp probe replaced...but all my EGT values change and none stay on 100. Bank 2 Sensor 1 rises if you boot it, otherwise it stays on 100.

Hi team,

Matt - Great news
The techs there definitely know their stuff to diagnose that. (They should though).
Plus great customer service to boot.

I still think you should get the drain mod done under warranty.
Mike pleaded his case and got his done under warranty, that's right isn't it Mike?

From AJG on another thread:

Quote:

The turbo drain mod in my view is essential. Oil builds up in the second turbo that only spins up above 2500 rpm which in normal driving can be never! Teh first time you overtake someone or give the beans the scene behind will be something out of a James Bond movie. The smoke can be so dense as to be dangerous. The drain mod gives an independent line back to the sump for each turbo stopping the back pressure building up and oil leaking into the second turbo. Not all 4.4's do it mine definitely did, if you drive round continually like a boy racer no problem, do sedate driving for 10 or 15 miles and then open it up oh dear, not good.
I was sceptical the drain mod would cure it, Green Oval garage knew all about it, assured me it would and it really has sorted it.

actually DrRob, it's here on your earlier screenshot.





but the 'units' is missing.

Do we assume grams?

Somebody screwed up there (at JLR)

At least it's a more accurate label description by saying inferred using differential pressure.
Which I suspected all along.

. Cheers, Greg

Hi team,
Turbo drain mod...
Yes I eventually wore them down at the MD, mainly by taking the Service Manager out for a little run which included me booting up to 2500 revs going down a motorway slip road whilst I told him to look out the back.
His actual words were, “quote”, er I see what you mean, it’s pretty bad isn’t it “
I knew I had won at that point and just told him to get it sorted, because it was still under Approved Warranty.
In fairness to him he said he would deal with it personally, and he did.
I have never seen so much as a whiff of smoke since, and at my last MOT it got a Zero reading on the smoke test even when he revved it pretty hard.

Father’s Day was good to me.... 62 miles each way motorway trip to my daughters saw my soot level drop from 17g at start to 6.4g back home.

Click image to enlarge

From your 2nd screen shot.
This is showing a passive regen in process..
Exhaust temps 290c and 320c.

Soot concentration and soot mass in grams seem to behave the same and the passive regen has brought the figure down from 22.4 to 14.7, which is what I regularly see happening when I monitor soot mass on my iid. although I have never seen a mass figure over 20g on mine.

Yesterday I had completed over 40miles non stop at over 50mph before I saw a full “active” regen at which point the exhaust temps shot up from 240c ish to 620c and the soot level fell to 5.0g, rising to 6.4g after 5-6 miles of non motorway driving at the end of my trip.

Matt - see if you get no amber warning lights over the next few weeks. If none, job done : From experience, analysing the IID can send you potty
Plus our tools don’t read Non Continuous Soot Mass unlike Greg and Mikes but it looks like they are probably the same given Mikes explanation in last post
Out of interest, do you have the famous P040D-00 (2F) fault code? https://www.fullfatrr.com/forum/topic50202.html
Read and clear your fault codes. Then read again. This one will come back instantly if you have it.

Just for comparison, I have had the PO40D.... Fault error showing ever since I bought the iid.
I have discussed it at length with my local independent Range Rover specialist garage , but not had the sensor replaced.
He did however tell me that his diagnostic tester would not be able to initiate a “Forced “ regen because the alarm would inhibit it.

Matt although some of these have been answered, pls see my answers:

1) My L322 was force regenned on Friday.
2) My car was idling for about 30 mins earlier - unavoidable, it was killing me!...
3) As soon as I plugged in the IIDTool my reading was 22.4
It should not be back up that high, take back to garage

4) I took it for about 40 mile blast at 50-70mph.
5) The reading went to 19 stuck for a while then later to 14.7 and stuck there until I got home. It immediately went up to 19 when I got home.
6) When I dropped a few cogs and revved the engine during the run my EGTs went from 500ºC to about 260ºC.
You don't need to rev it, I do mine at 50-60 mph / 1200rpm.


1) Has anyone found out whether "Soot concentration inferred using differential pressure" is correlated to or the same as "Non-continuous Soot Mass"
Thinking is that it is the same, the new label is more elaborated

2) Is is usual that this number will go down a bit then stick during a blast?
Maybe if traffic interrupted the burn enough and it's below 17g then it thinks it no longer needs regen

3) I note I did note reach 600ºC like Greg's does when he is regenning.
That's good. But since your garage did a forced on Friday you shouldn't have needed this.

4) Can a regen happen at 400-500ºC
Yes regen happens in 'steps' starting around 350, mid-400's, 500's and finally around 630 degrees. The higher the temp the more soot is fried.It goes though each step like a gate, 400odd degrees for a few mins then it asks itself speed constant, fuel level ok? Onto next 'step' Eventually reaching the full incineration 620 degrees.

5) I am wondering if I am not regenning at all... and the blast is just burning some soot out.
anything over 400 degrees will burn soot. It's just that, if a regen was done recently it tries not to do them too often but will do a mid burn as I've witnessed. Call that passive I guess. Like upkeep. When driving conditions allow it will set to work even if not a 630 degree burn it still takes the opportunity to have a little burn if soot is over 17g

6) It is usual to be stuck 14-ish grams whatever, or should I expect single digits. -
Yes a full burn 630 degrees will (should) see your soot drop to 2-5grams. Sometimes this can take 20 mins and it will stay at 630 degrees but it might drop to the lower 'step' around 550 and if speed is constant it will rise temp again. I've had burns end early leaving me with more than I'd like but a successful burn should take you 2-5grams. Interrupted burns will yes leave you low teens. As per answer to Q2.

7) Does anyone know about the regen data and whether it updates "Number of partial successful regenerations" etc.
Not sure as I have not updated my IID. Your update and DrRob's is newer than mine.

8 ) What range of number of grams of soot should I expect?
A successful active regen will take it down to 2-5 grams. This comes back quicky and it starts to auto trigger at 17g. If driving prevents regen like mine often does it'll climb up towards 23-odd - when the yellow light goes off. If this happens get her onto 50mph with a good amount of fuel because it will turn to red very very quickly.

9) The manual says not to leave the IIDTool plugged in all the time??! Any thoughts?
It'll run your battery down. Ask me how I know!


Greg

1) Should the regen and therefore soot level reduction happen in a straight line?
Don't know. It wants a constant speed and throttle.
