Ummm, CT is the vehicle in question ULEZ (Euro 6) compliant, or was it registered before 1st September 2015? That may have something to do with it?
i.e. do you use DEF fluid, or not?  “If it ain’t broke, don’t fix it” -where’s the fun in that?

@Gremlin500
It is Euro 5, not euro 6 (NO Ad Blue)

@Kot
It's a standard standard SDV6 engine as far as I know. I have tried many profiles from both Land Rover and Range Rover within the app but can't find any of the most basic sensors you mentioned. I'll happily revisit this but currently I am using the: Range Rover 2014-2015 L405 3.0 Diesel V6 profile.

Does the Euro5 type mean further distances between regens? Sorry for my lack of knowledge on this if it is a basic question..

Thank you all again.

Still persevering with IIDtool!

Anyway, did a 320 round trip to Aberdeen, all on dual carriageway, so speeds of on or around 70mph, so I was expecting the “measured soot mass” to have drooped from my first reading of 12 but I was surprised to see it has actually gone up to 17.
I had expected this trip to have kicked off a DPF regen and burn this off, so am I looking at this the wrong way?
I can see the “average distance between regens” has gone from 145 miles to 339 miles, so assume that’s good?

@Alan:

Your vehicle is not behaving typically, well at least not the same as mine (TDV6) but the V8 should be almost identical. Forget the DEF/no DEF question above, DEF only relates to Nox, not Soot and anyway it’s downstream of the DPF, so the AdBlue addition can have no effect : sorry, my Red Herring

On a recent round trip from Newcastle to Manchester (almost identical distance to your trip) on fast roads/motorways, my recently regenned DPF slowly filled up with soot to 50%, then regenned just after Preston on the downward leg, then filled up with soot again on the way home So next day, I had to fill her up, and take a run down to Stockton & back just to regen THAT’s typical!

I have NEVER EVER managed to reduce soot even by 1% by “passive regen”, only by active regen, which normally wants to kick in at 50% soot, then takes 20 mins or so to get to 7%, at which point it ceases.

Something seems wrong with 850 miles between regens, you would expect 150-250 range as being typical (Do others agree?)

Some of your parameters make no sense, but I use the “Kot Kit” not the iiD tool.
You can be on the same page as the rest of us for £25-30.  “If it ain’t broke, don’t fix it” -where’s the fun in that?

@Gremlin500

I really do appreciate the reply, but maybe you're mixing up Alan's and my replies - easily done as it's gone so convoluted over the last few replies is this thread, sorry.

I DO use the 'Kot Kit' setup, although as mentioned, I don't seem to be able to monitor the same sensors as you guys.

I wonder if there are others with a (2015?) SDV6 that have the same problems in regards to the sensors?

The 850 mile thing is something I'm not overly worried about, but as everybody else in this thread is seeing regens much sooner it has piqued my interest..

Thanks.

Yes, that looks like a reply to you CT, sorry to muddy the waters

My regen mileage looks to be within acceptable parameters  Got - 2017 SDV8 Autobiography in Loire Blue

Sorry guys, a “senior moment” there, you seem to have both worked it out.
CT, have you tried not using a profile, just selecting “all sensors” then picking from the entire list?
These are the sensors then available on my V6:

Thats all good! going from 12g to 17g on such a long trip shows that you have had some passive regeneration, but you never get enough to match what you are always producing. Maybe on the autobahns you might
Again such long runs will increase your "Av distance between regens" as yours surely has. No issues here. 2018 SE SDV8 4.4 Byron Blue

Excellent, cheers for the confirmation  Got - 2017 SDV8 Autobiography in Loire Blue

For anyone who only has the Autel AP200, the relevant metrics that I can see are:

Distance to next service (km)
Oil quality fuel dilution factor - inferred
Diesel particulate filter remaining volume (L)*
Diesel particulate filter soot concentration - Inferred using differential pressure (g/m3)
Distance since diesel particulate filter regeneration (m)
Calculated soot in oil (mg)*
Particulate filter differential pressure - Measure (hpa)
Number of successful regenerations*
Number of demanded regenerations
Incomplete regeneration status*
Particulate filter regeneration inhibited status
Number of partial successful regenerations*

Highest Diesel particulate filter soot concentration - Inferred using differential pressure (g/m3) observed - 21
Highest Distance since diesel particulate filter regeneration (m) observed - 688665
Average distance between regenerations over the lifetime of the car (calculated by me) - 485 miles

@hmallett----Interesting, I have the AP200, and use it for DTC only, never crossed my mind on using it to view associated DPF readings.
Can you list the procedure you are using to view your metrics. Can you see graphs etc?

I can claim some success with observing my first regen but still feel I’m quite a long way from the Jedi status of those above who’ve contributed loads on this subject.

I was interested to see after the regen had happened that the measure “DPF distance since last regeneration” did not click straight back to zero as I’d expected, rather it did a gradual wind back to zero which took a minute or so.

My main frustration at the moment is not being able to pick up all the data points that others have posted here. In the screenshot of the app, the missing items just show as “not selected”.

I’ve got a 2016 SDV8, so fairly mainstream model I think. I’ve tried some different connection profiles in Car Scanner Pro, but presume I should be using “Range Rover Range Rover 2013-2016 V8 4.4 Diesel”. The data I’m struggling to pick up are:

DPF/GPF soot (Normalized Trigger for PF Regen)
Particulate Filter (DPF) Regeneration in progress (0 - no regeneration, 1 - passive… etc etc
Average distance between PF Regens

Would much appreciate some guidance!

EDIT: I need to update that pic sorry, the last sensors is now “miles since last regen”

I think I’ve tried that advice, but in typing this reply I think I’ve worked out that I can simply ignore the “connection profile” setting altogether rather than trying to base the profile around the “OTHER BRAND” that I’d thought was for a generic list.

I will try the former and report back! 2016 SDV8 AB
