Hi, Newbie alert! Just jumped into the Disco 'ecosystem' with a Disco 4 (2013)....

Been reading a lot about the DPF and potential issues. I've also read that some OBD2 scanners can check the DPF to see if it's filling up or keeping itself clean. We use the car regularly for short journeys and then intermittedly for long journey.

I want to get a scanner that will tell me how full the DPF is getting so I can make sure we avoid problems by doing longer journeys to help keep the DPF clear.

Does anyone have experience of a scanner that will do this? can you recommend a scanner, or which ones to avoid?

Thanks in advance,

(Newbie) Col

You shouldn't get a problem, provided you don't use supermarket fuel all the time, and get the revs up from time to time, so the DPF regenerates.
No idea about the scanner for that, but I imagine @gstuart does.
 
Hiya

The gap iid can force the DFP to regenerate but not sure I’ve seen a scanner yet that can tell how full it is

Think the D4 regenerates itself every 500x miles

will have a dig around and see what I can find out for u
 
Just looked on the gap iid website , learn something every day , gap iid also shows the DPF Remaining Volume

Assume other scanners will do the same but alas don’t know which ones as having the gap iid that’s the only one I know

Hi Turboman, gstuart.

thanks for the input so far. the gap iid is more of an investment than I was planning but if it can provide an indication of whether the DPF is filling up, that will make sure I can avoid problems, so I guess it will be worth it.

hiya

if u also check out the D3 forum https://www.disco3.co.uk/forum/

they have ones that come up for sale

also island are currently selling them at the old price , around £420 https://www.island-4x4.co.uk/integr...411-da6412-da6413-da6414-tfiidbt-p-27303.html

hope that helps

They are not cheap, but your use of the word investment is quite right, it is a very useful tool and best of all second hand they only lose about 100 quid in value and one visit to the delaer will cost that, so first time its actually neded you have broken even.

Sadly they have recently just gone up from low 400s to low 500s so get looking before everyone cottons on!

plus 1, seeing dealer now wants £180 per hour plus vat

dont know how much stock island has left considering there doing them for around £420

that autel ap200 doesn’t look a bad tool to keep in the disco

there’s another one I’ve heard about, just been trying to find it, not the RSW solutions one

Well I guess the way is to buy 2nd hand for miid 300s then when they sell it, it will be worth what they paid for it.
Think mine was under 400?

indeed, see there always coming up on the D3 forum

think I paid £405 for mine , when I got it went for a drive and collected it from island , also stopped off by the Ferrari garage as they had around 20 x of them all lined up outside , drool

will get an autel ap200 later on to keep in the disco
 
I've been looking into this a bit recently.

I *think* the icarsoft one will do regen, but I'm not sure if it gives a soot readout.

There's a YouTube vid of someone with the gap tool showing the soot number creep up and then hit 23 or somthing and the (active) regen cycle starts.

I can't help but think that the "soot number" is somthing created by the tool, rather than the ECU, so may not be represented the same across different tools. It's really just differential pressure across the dpf (as I understand it!)

As a side note -

I'm looking to get some sort of diagnostics - is the gap tool really worth the 4x price hike over the cheap icarsoft thing?

There is no doubt the Gap is good very good in fact, but unless you need to programme then the icarsoft for 100 quid will do what most need an dwould be what I would recommend for most people.

I paid 100 for my icarsoft and sold it a year later for 95!

There are other makes coming out now to compete with Gap and it seems weird they have raised their prices!
As the D3s age 500 quid which could be as much as 10 percent of the value of the car and in some cases more just doesnt add up.
Plus of curse people can lay their hands on 100 but 500 is getting into serious money.
 
I looked on eBays completed items for the Iid tool. Prices seemed to be around 330-360 used. Which is odd, as a used item will require a £60 licence, which puts it up to virtually new price (about £435 from a couple of different retailers).

I can't find anything about the icarsoft unit and dpf, other than it being able to force regen. I can't find details of what sort of actual reporting it gives on the dpf state.

If you have a unit, could you shed any light on this?

Thank you

Try a search on the disco3 forum as there was a guy with dpf issues on a late D3 and in the end he managed to get the before and after pressure reading from his dpf, but I cant remember which tool he used!
It was in the last few weeks

I think he also posted on here first, but search is down!

hi mate

see the guy used a icarsoft to do a regen

so assume there’s sensors either side of the DPF and it measures the differential pressure

Not sure but I can remember he got the dpf sensor readings, which told him the before and after readings, which is what the car uses to suss out if it needs a regen or not.
He must have been one of the first as its nothing something I have read on there before.
 
I found a neighbour who has a Bosch KTS 520 diagnostic tool. Plugged it in and it seems to say the dpf is all okay (number of regens = 40, number of failed regens = 0) but it also gave a soot mass value of 5.2g. Problem is I can't find any info online about the capacity (I'm assuming the soot mass is an actual value rather than has a different meaning), so I don't know is 5.2g is good or bad. Anyone know?
I've had a look at the icarsoft - it says it can force a regen and I read one of the customer reviews said that it gave a reading of how full it is.

What would the gap iid tool provide over the icarsoft? does it provide more info or, as it seems to be dedicated to LR, is it just better 'tuned' for Land River?
 
Though I don't own a Disco 4 to use it on, I'd check out the Foxwell NT-520/530 models
I can only state that I use the older NT-510 to monitor my wife's 2011 BMW X5 (E70) diesel system and can do for DPF regen.

hi

if u read page 1 of the link one poster lists some figures , so see if urs is similar at different revs

At idle 0,3 kPa
At 2000 rpm > 120 km/h > 4,2 kPa
At 2500 rpm > 150 km/h > 8,8 kPa

I also think the differential between the 2 x sensors is very important as I then assume that tells u how clear the dpf is
