Hello
So I set this up on my car.
So the trigger is at 92/93% so I assume that a Regen will happen soon. At the moment the Km until next service is climbing.

So during a short drive I saw that a passive Regen happen for a minute.

So I had a new DPF fitted under warranty but I don’t think it has made a difference.

luxmoggy---I get the standard "2" active regen at 54%+ never seen it so high at 92% without it going into active regen. Highest i have seen was in the 70's but by then I am tending to do longer journeys just to ensure it starts a regen.

I wonder if they also installed a new software update as well as a new dpf with you?

Definitely watch this on your next journey, Because now you are close to an amber dpf alarm, if it fails to do an active regeneration!
I would be interested on what develops, I sometimes even try to accelerate hard and bring in 2nd turbo (when up to temperature) to prompt it

Maybe you are not travelling long enough and you have several failed Regens? but from what I have seen, if you have a failed regen it stays at 100% until conditions are met for active regen to start.

its also interesting that your average distance between regenerations is 750km (466 miles) I only get 1/3rd of that.

My last oil change was 3 months ago, I have done just over 2000 miles, and the service message now shows 950 miles to go to next oil change??? so that will be tomorrow at this rate Oil and filter at the ready  2018 SE SDV8 4.4 Byron Blue

Hello Kot
How long a journey at a good speed have you seen the active Regen take place?

On the way to work today there were short passive events.

Thursday is a holiday here so will be able to do a longer run in the car on the hopefully empty Autobahns.

Also the km until next service is still going up at the moment. SDV8 AB MY 2020

So it got to 100%. Active Regen started. It was running for about 10 minutes.
No warning on the dashboard. It is was only as I had my iPhone connected that I knew. Would have normally stopped the car but as it was running I drove on. It completed or finished. The percentage is at 100 so I assume it failed. Don’t know why.

The service due in Km has gone down. SDV8 AB MY 2020

If you read page 1 of this thread you can see the first 2 active regions I captured.

I believe you need to have engine up to temperature and above 80C oil temperature, I have seen AR's start at this temperature it could be lower.
Have at least 1/4 tank of fuel, but I have seen AR's below this level but if you get an Amber alarm, threads on this site suggest it may not allow a AR start.
I have seen AR above 42 mph, also there is a time element but usually its started after 20mins.

Regarding passive, as long as your exhaust is above 250C it starts to passively burn off the soot, but dont forget you are producing more, the higher the exhaust (faster you go) more soot is burnt but more is produced I wouldn't worry about the 1 trigger not being on all the time. it concerned me early on but now accept exhaust temperature above 250+C it naturally occurs the number 1 trigger event is immaterial. 2018 SE SDV8 4.4 Byron Blue

Hello
I saw the exhaust temperature above 500C. So it was working. But didn’t complete. I will go to the Autobahn after cooking dinner. I can hopefully get it done. SDV8 AB MY 2020

So I have just driven 180km. 140km on the Autobahn (100-170km/h)
No Active Regen triggered. I don’t understand why… SDV8 AB MY 2020

Go to Data Recording on the app
open the last saved file
select DPF soot and Exhaust Bank1 sensor 3 &4 and Particulate filter press ok

You can then select on 1 graph or separate graphs.
You will be able to see the history of your journey can you post your graph

example shows one of my interrupted AR, you can see clearly when 100% soot ends (Red Line), thats the end of an AR. Do you have the same?

The one from earlier where active Regen was triggered but didn’t seem to do anything, didn’t complete…

The %soot (DPF soot Normalised Trigger for Regen) is not changing even though its clear you had an AR complete OK the pink line shows the trigger did operate to a 2 and ended successfully but the soot% (Red line)is still showing a false reading (100%).The pink line also shows you had correct passive Regen as well.

I wonder if the %soot pid is maybe corrupted? try removing pid from your dashboard, close app and remove app from iPhone memory/cache (dont remove actual app from phone).
Check for updates of app.
Then open dash and search and add soot% pid again.

If it doesn't solve problem keep monitoring it, see what the next regen brings, if you miss it you can retrieve it from history at your leisure.
if you get an amber alarm on dash take it dealer as a Red could happen very soon after an Amber.

I doubt its an issue with new DPF fitment, not having sensors reattached correctly/loose wires etc as you clearly have correct exhaust readings from bus etc. Also algorithm did generate a trigger and AR did work. Do you know if they did any software updates as well? It would be worth knowing that.

1 Last thing, the Car profile I see the app has 2 possible vehicle groups via Range Rover or via Land Rover you can get to same car profile from either entry point. I doubt it makes a difference but I am via Land Rover profile. 2018 SE SDV8 4.4 Byron Blue

I tried that. It is still 100%. I have contacted the developer to see what he thinks.

For me I can see that the KM until the next service is climbing again after falling during the active regeneration. I have done about 300km since. As it says the average is 750km between it will be in the next 2 weeks. I will keep an eye on it. SDV8 AB MY 2020

I am on about 650km since the last Regen. So I except it to happen soon. Looking at the km until next service is increasing again. Most of my next journey I can continue if it starts so I can go until it is completed.

The soot % is still 100%. SDV8 AB MY 2020

Did you try removing the obd2 device and seeing if that resets the soot value?

the device just reads what the bus is outputting, after a regen it should be reading between 6-12%, unless the device is locked up? 2018 SE SDV8 4.4 Byron Blue

I tried a few things. I got a new phone today so will set up the device on the new phone from scratch. About half the time at the moment I need to replug the device again when I start the car. The other times it is able to reconnect without me doing anything. No active regen today. SDV8 AB MY 2020
