I’ve just bought the GAP IID so that I can check faults etc but also so I can monitor the dpf on our recently purchased 2013 Disco 4.

I couldn’t find any useful dpf live values to monitor so I asked GAP to help me. They’ve said there aren’t any!
I don’t think that’s right - is it? I can’t believe it won’t show the basic “how full is the dpf” like most other tools.

if so I spent £450 on something that isn’t any better than other tools that cost a fraction of the GAP tool.

please tell me they are wrong.
 
Try a search on here, as I am sure this was recently covered on a D4?
If not try the D3/4 forum.
 
I find it strange to think your gap doesn’t show any DPF values.
Have you had a good look around in the live values, there are a lot.
My Gap demo screen (not plugged in so only demo) shows DPF info. Never had to check ours as our(L322) driving habits shouldn’t require intervention so have not looked tbh.
I know @Hippo did a video of it (although on a FL)
@gstuart has a D3 and a Gap so maybe of more help.

Is the D4 getting into add blue territory?

That’s strange as it says it does on there web site

hiya

just had a look and it shows it does on there web site
 
All is well thanks Gary.:)
Not up to our thighs in snow so probably a drought in the summer, but hey we will deal with it.
Hope all good with you:)

Thanks for your replies. they are helpful.

I've used the DPF remaining volume and DPF pressure diff live values. the DPF remaining volume returns a zero, i.e. "0 L". so either the DPF is absolutely clean or the reading is incorrect. I asked GAP about this and they said they have given access to all the available live values and if it's not showing a figure then it's LR not providing the information. I'm really surprised at this as there is that youtube video of @Hippo seeing DPF soot concentration levels on a Freelander 2. But apparently that isn't available on the D4. I'm not sure why LR would remove the ability to see information about the DPF, but GAP state that they have done so.
 
Smells of fish in ere. :p :eek:

The disco 4 only went up to eu5 on the diesel. Eu6 onwards is ad blue so the D4 never had it. It never had the newer LR ingenium engines which are eu6. They kept using the ole crank snappers. :p

EDIT: as a side note the 2016 d4 is EU6 and ad blue, stopped production in 2017

I have had a look in demo mode on the iid on D4 option and can only see the references mentioned in the post above. Cant get into the untested menu on it.

The more superior Freelander 2 can display more info about the dpf. But it is found in what was previously called the "untested" menu under the diesel engine section. Untested menu was changed to complete menu int the latest iid update. Probably still untested as theres loads of issues. I had to ask for special access to the untested/complete menu option.

Not sure why i can't see the D4 untested menu. I have in the past.

Video below of a Freelander 2 and where and what detail i found.

You guys obviously know a lot about these vehicles.

Gap have suggested I update the engine ecu and try the live readings again.

will report back when I’ve done this.

Is there any reason that you know of that all FL2 builds shouldnt report the info in the same way as yours?

Im asking as...

We are set to "inherit" a 56 plate, that, unfortunately, has the, at that time, optional DPF fitted. Its evidently a much earlier motor than yours, but im hoping that the GAP tool will still report on ours in the same way as it does on yours.

What i guess im really asking is if the ECU is the same for all FL2, or if your later one may add some stuff that is needed for the DPF info with GAP?

(im wanting to buy the GAP specifically for dpf stuff on the 56 plate fl2)

Thank you.

hi @Hippo

ref the untested section it seems to have gone in the new gap update , has on the D3 anyway , spoke to gap and they said some sections of the untested is now incorporated into the update , but the separate untested section that useto be an option in the menu isn’t there

I can't say yes or no to it being able to read the same dpf info as mine without first testing it on one. I have one of the last MY15 builds with the SD4 engine. The SD4 live data view on the iidbt provides more info on the engine in the tested section than the lower power TD4 engine live data. I guess the bits it doesn't show are in the untested section. So they may or may not work.

The dpf stuff is all in the untested section on the engine computer on my SD4. I can't remember seeing it or not when i last looked at a TD4. I had a look this evening in demo mode (yer can download the iidbt tool app to use in demo mode to look round it without buying one) and i can't get into the untested section while using demo mode. I regularly lose the untested option and have to reprogram it with the same software again to solve this. Some days it allows entry and some it doesn't. The untested menu worked when connecting to my car thus evening.

If lr made the info available then gap claim they can display it. But they admit most of their sales are for use on the bigger lr's. Hence most of their development work is on those vehicles. So the FL2 isn't as far forward. Theres all sorts of talk about how fantastic it is as a product and how it can do more than any other product. Most of that is bs. Lr's SSD can be used to enable the drive train view on the radio/sat nav display which is hidden on the FL2. The iid can't. The iid will let you download firmware updates to yer vehicle when lr hasn't released for your vehicle. So by default some peeps consider it can do more because of this.

If i get the chance to look at an early TD4 i will.

To be frank i don't have any problems with my dpf. I just put the video online as there's a lot of false info about them.

I will check tomorrow what version firmware mine is running. The last update was last year. To be frank i didn't notice anything different in the last update other than the screen layout being different. And some of the fonts have reduced to 1mm or lower so impossible to read. They seem to have justified the text rather than letting it wrap around.

I had to ask for special access to the untested menu. Was told to be careful and treat it as untested. Some works. Some don't. Some is just wrong info. I offered to help them for free with testing and gave them a link to my youtube. The email had a few questions in it but the didn't take up my offer.
 
I’ve borrowed a friends Bosch KTS system and used that to see what info is available and it gives several DPF readings, such as ‘soot mass’. So, either the KTS is interpolating that figure somehow and/or is using data that the gap iid isn’t.

There are many other OBD tools which state they show dpf information.

so, if the gap iid is so good, why doesn’t it show me anything at all?

as stated earlier, the gap team have asked me to flash the engine ecu. I’m not confident that that will do anything though.

Controversial thought but maybe it’s just not as good a tool as we all think.

Thank you. I have submitted this query to Gap Diagnostics -

Hello,

I was set to buy the IID tool for use on an early FL2 that had the dpf fitted as an optional extra. I am buying the tool primarily to view the live dpf data - that is my main requirement.

Your faq states that the dpf data is displayed.

One of your users has even uploaded this video of the DPF date on a later freelander -

But...

From reading this thread, it seems that the DPF data is not displayed on all builds - https://www.landyzone.co.uk/land-rover/gap-iid-no-dpf-info.356510/#post-4784344

And can seemingly appear and disappear from the "untested" section?

Again the DPF live stream is my primary interest in buying the tool.

How can i be certain that the tool will provide me with the info? Basically, will i be able to get the stream, as per the user in the youtube video?

The UK registration is,,,,

I can, with some trouble, probably get you the VIN if needed.

The IID tool is not pocket change. If you can tell me with certainty that i will be able to pull the stream from my motor with the tool, ill buy it. I just need assurance!

Thank you
