Anyone know at what level the regeneration starts on a Fiat Ducato 130 multi jet . I am currently showing a level of 85% . I was under the impression that clogged was 200% and regeneration at 45%. Can anyone confirm. Also the Multiecuscan for iOS doesn’t show ash level. What software can I get for that.

My 150 (Euro 6B - 2018) starts regen at 100-102%, never out of this range.
DPF percentages are in the 0-200 range for some reason..
0-120% is 'normal clogging'.
120-150% is recoverable via forced or off-vehicle regens.
150+% is dead.
Mine still (after 18k miles) cleans back to 8% clogging every time.
With this engine (and my VW car too) passive regeneration doesn't exist - all cleaning is done by active regen.

Thankyou for that. Really useful. I need to monitor the levels a bit longer to see what happens from the sound of it. A recent forced regen only took it back to 69% but the dpf sensor was faulty, so I’ve replaced it. Didn’t want to do another forced regen so am monitoring it and at 85% nothing has happened yet. I think there must be some sort of passive regen occurring because I’ve done 3000 miles mainly motorway with no regen showing.

What while going along or what?
Sorry never had anything to do with this stuff, but why would you want to know?
Fiat garage charges £120 plus vat for diagnostics.
looking for something like “Dpf monitor” but on iOS.
MultiecscN doesn’t seem to give soot content.

No worries. I had engine management light come on so needed to diagnose what caused it and to be able to reset it so I could get home. Fault code identified problem. Able to purchase replacement sensor. Diagnostic with main dealer would cost about £140 plus part plus labour for replacing, so ultimately saved myself about £100
Now need to check dpf regeneration is working correctly and ensure filter is eorking correctly

Just had a Diagnostic test with print out for about £50
Not from a Fiat pro dealer though I bet. My two local ones quoted that price last week. I got scammed by an independent dealer and ended up with a £2000 bill years ago so don’t trust them at all. Of course his £3000 machine had to be right. Gone are the days of the error codes being a pointer as to what’s wrong. Let’s just keep throwing parts at it till the problem goes away. At least now I can see what the codes are and if I get hit by one when out and about I can possibly clear it rather than a breakdown. I’m sure your test was fine, but personally it’s nice to be aware.
The days of setting the points with a Rizla are long gone. (used on my C15)
The OBD2 port allows interogation of the half dozen or so computers littered around a modern Ducato to deal with the 10s of sensors again littered around that are used to deal with all the environmental BS. You have 2 choices either be prepared to pay £7-10k for Fiat pro to change parts apparently willy nilly or DO it your self with a PC and Software like Multiecuscan.
A simple sensor fault can lead to a blocked DPF and lots of Money or understand whats going on.
The first graph is a sample of a good motor. The second is one on the way to a blocked dpf that was regenerating every 70 miles as opposed to a more normal 300. And no error codes to tell you what to do. A simple£30 sensor not changed intime caused this grief.
Did that help?
By the way you even need this software just to change the oil.
Not entirley true you can physicaly change it but the engine will go into limp mode when the ecu feels like it.

Is this the same with all new vans? Are you all doing this stuff,?

How does the multi scan work? Do you need to plug something in and if so what and where? The reason I ask is we have our tyre pressure alarm come on and the tyres are definitely above the set point, I’ve read it can be caused by a malfunction but can’t get it to reset.
You install the program on a windows computer, and then attach that computer to the vehicles OBD port under the dash.

Is this done via usb or do you need specific cable?

Was it the differential pressure sensor you changed?
If it was did you carry out the sequence in multiecuscan to reset the system? Mine dropped the numbers quite a lot after resetting.
You have to tell the ecu that it has been replaced.

Yes dpf sensor. The garage assured me they reset the system, but I’m not 100% sure. Have been deliberating whether to do it myself again just to be sure, but not sure whether it can be done now I’ve used the van. Anyone help on that point.

No, all new vehicles. Going to be a nightmare here soon with all those who drive at 5kmph cabbage watching getting lights coming on all over & having to pay fortunes to get sorted.
You need a obd2 reader that speaks Fiat there are 2 used in the diy world
Windows laptop and multiecuscan (as previously mentioned) or Alfaobd for Windows.
Android phone, tablet and alfaobd . Specific obd2 dongles are also needed as as not all talk Fiat. Gendan is a distributor for both mes and USB dongle . For Bluetooth I use a vgate from ebay seller in Porthcawl s Wales they work, cheap £10 ones do not. To use other ecus you will need a yellow adapter.
I use a win10 obdsx USB dongle and multiecuscan
Alfaobd android version with Samsung j6 phone a8 or tabA tablet and vgate usb dongle. More detail in previous threads
Or is someone going to write an idiots guide.
does it allready exist?

I've just reset my service counters after an oil change and it shows 104% clogged but it has been 417 miles since the last regen. The average mileage between regens has been 450 miles so I assume/hoping that it will do another before too long. At the previous service it only showed 16% clogging but had only done 15 miles since the last regen.
On the recommendation of Alanche (post#9 above) I have got the DPF app he recommends and will now keep a closer eye on what is going on between services. So far, over 18,600 miles it has done 53 regens, which I think with one exception were all passive. On active regens, which can increase the oil level, I have a mate who is a consulting engineer who works closely with Millers Oils. He reports on damaged engines and regularly asks Millers for oil analysis. When diesel is forced down the bores and past piston rings to dilute engine oil, there is apparently a 3-5% maximum dilution threshold beyond which engine damage is inevitable, hence the need to avoid any possibility of seeing rising dipstick oil levels. Interestingly he mentioned that a fifth injector downstream before the DPF is the optimum but very few manufacturers do this (on cost grounds), relying on existing injection into the bores.
Millers have a DPF cleaner which apparently reduces the temperature at which regens take place which is apparently good for taxis and vans which don't get the chance in towns to reach the temperatures necessary for passive regens.
I have just bought this on your recommendation to use in conjunction with the DPF app. My Multiecuscan reported zero ECU errors or recorded fault codes and I have had no warning lights but does that necessarily mean that all the sensors are working correctly to enable regen to take place properly? I understand from your post #15 above that you had a sensor fault and that failure of this, (or other critical sensors) will cause regen issues without you necessarily being aware. Can I ask whether Multiecuscan will show/report faulty sensors as an error or do you have to rely on the OBD module and something like the Car Scanner app to look for faulty sensors?
Multiecuscan does not specifically tell you if a sensor is working or not. it is bit like reading a book the story is on the pages the obd2 code is chapter title. Here is an example of how to determine a dpf differential Sensor problem. The second is how to save live data as a csv file to be analysed later.

The typical regen rate I have seen reported is in the 3 to 400 mile region. I would be happy with long intervals if your dpf differential Sensor is showing sensible values. It shows it is not producing bucket loads of soot to deal with. The injector deviation values will be interesting, I suspect they are low (Ie good).
Have you got a clean exhaust pipe?

Can I say, I'm happy that you, and most people, (sadly not all) who need to understand these things, can, because to me it's like reading a doctor's prescription.
When I first acquired my 2007 Fiat X250 in 2017, I thought it would have a Cat. and a DPT and bought a Multiecuscan with the licence (you could buy the free version but that did not show all reading, but the licenced version was to main dealership standard?)
When it arrived, I thought, too complicated for an old man to understand, especially when I replaced my old exhaust for a stainless steel one and found that my Euro4 Ducato was original but had neither a Cat, nor a DPF??
I spoke to Grant at Gendan (nice, helpful guy) explained my need and I now have a Fiat specific, handheld and the Multiecuscan remains, unused, in the van just in case I have a serious problem which I cannot fix, and I take it to a garage that knows how to use it?
So far, happily, that day has not arrived as most things I have fixed myself!

My previous van was a 2008 X250 but did have a cat so perhaps yours has been removed - they were often the target for theft. Diesels were so much simpler before DPFs
