Coding in DPF with diagbox

[crabhunter]

Ok, here's where I'm at.
I've installed Win7 32bit, found all the drivers for it and installed a program to mount the iso.
I've just installed Diagbox 7.02 and the installation has failed, this has never happened to me before.
I'm in the process of re-installing it.
I have incremental updates up to 7.82 but I have one that takes me from 7.02 right up to 7.57 in one go.
I will see if the 7.58 update gives me the Data access problem I got whilst on Win10 64
I'll report back when up and running again.
This has become something of a challenge now, I can't believe how much time I've sunk into this now.

Mike - if it has been deactivated, reinstalling it again won't work. It has to be not only uninstalled, but cleaned from the system. If you want me to assist via remote, I should be able to sort this for you - details as per my last PM.

Ok,here's where I'm at now.
I've got Diagbox 7.58 installed and running on Windows 7 32bit.
I've updated my interface to 4.3.2 and the serial has a "C" at the end.
I still for the life of me cannot find an option to tell the ECU the DPF has been replaced.
Time to take up Marc's generous offer.

Hi Mike - further to our remote diag session, and the obviously missing option for the DPF replacement - I think it is worth mentioning the following:

I'm not sure if we mentioned the vehicle's history or how long you have had it, but:

The only thing I can think of is either the BSI has had an option changed on the type of particle filter installed - and that is wrong - which would effectively remove the option from replacement parts, or;

That the engine ECU has been re-mapped / and or the DPF 'deleted'.

I've looked at another video with your engine ECU and although it's in Croation / Bosnian, after translating the menu options selected, it is clear to see that the option is there.




Have a careful look at time index 0:30 - this is the menu list we accessed that lists all the replacement parts including the injectors at the top. Then you can see the option he clicks - which was not available to us...... so something not right - it's as if it is not there because it knows there is no filter.....

So I think it might be worth going into the BSI (be very careful not to change anything at this point), and just see what entry is listed against the Particle filter / FAP type.

I've owned it since new and it's never been mapped or had any "Deleats" I've seen that vid too. I'm out clearing my head at the moment, when I get back I'll have another look through the BSI which I have been through before.

[GiveMeABreak]

Ok, good idea - well that rules that theory out - so let's see what the BSI is reporting.

[crabhunter]

Well I've had a good look through the BSI pages and it's reporting that there is a DPF and the name of the ECU but I can't remember it now.
I can query it and get all the information I need from it ie soot levels, miles since fitting, etc.
My next plan is to try and find the earliest version of diagbox that supports my van and try that version and then each one up to and beyond 7.6
I can see a trip to the dealers coming up though
Something's definitely not right.

It seems the problem might lay with my clone interface not being full chip. The van is in for MOT on Wednesday and they are going to try and code in the new DPF with their Snapon machine.
I've ordered a new interface that is full chip and I'll see if the option is there even if they manage it at the garage.

The Snap On machine should do it. Two places I have used have had them and they could manage most things.

[GiveMeABreak]

This will be interesting Mike - normally if the VCI isn't a full chip kit it simply won't communicate with certain ECUs at all, showing them as greyed out or 'no communication'.

Your Berlingo is a full CAN vehicle, but I would be surprised if the software menu options in Diagbox vary at all once it has established dialogue with the Engine ECU in this case. The way to know for sure of course is by checking with a known full-chip kit and seeing if the missing Replacement DPF menu option appears.....

Do keep us updated on what the Snap-On says.

[crabhunter]

Well here's an update and it's still not good
My new interface arrived and that still didn't show an option for replacing the DPF.
The van went in for MOT and they hooked it up to their Snapon machine.
They said it was quite straight forward, they were offered the choice of renewing the filter and the machine reported it had been done.
When I hooked it up at home it's still showing total mileage, same soot and cinder count and regen is still disabled.
They have said it will have to go to a main dealer
I have the number of a fairly local independent Citroen dealer so I might contact him first.
I can't believe what a nightmare such a simple job has turned out to be

Sorry to hear that but not so straightforward obviously - and something is awry - it may need the engine ECU software updating - which only a dealer can do. I suggest you bypass the indy Mike - and go straight to the dealer as an indy is 99% unlikely to be able to be able to update the software and will most likely only have access to a Diagbox clone like you already have.

On these occasions, it might pay to bite the bullet and go straight to the horses mouth to get it resolved or you will likely me laying out again and no further on. They will only charge about £90 an hour for diagnostic time and that should include any diagnosis and any BSI / Engine ECU software updates needed.

Here's an update on my sorry story.
I contacted an independent Citroen specialist but he didn't fill me with confidence so I made the decision to go to the main dealer.
Before I got round to it, Covid struck. I expect the dealer is shut, and I'm far too busy to get the van over there anyway.
A few days ago I sent a request to join a diagnostic group on Facebook. They made it clear it was for professionals only.
Well, they let me in and I struck up a conversation with someone on there.
He said it would never work in offline mode and that you had to be connected to Citroen's server to do certain things.
However, he said he'd done several by going in as a Peugeot 206, Citroen C3 or C5.
Well, 206 didn't work but after trying a few different C3 models I hit gold, or so I thought.
Although the option to replace the DPF was there, after selecting it I wasn't getting any sort of confirmation back from the software.
Finally, I tried a model that after selecting the option reported back "Learning completed"
If only it were that easy I then went back in and read all the values but nothing had changed, just like after the snapon at the garage.
I went back to the Facebook group only to find I'd been removed and my conversation deleted.
I will keep trying different models and report back if I'm ever successful.
As soon as lockdown is over I'll get the van over to the main dealer.

It's what I already mentioned in my previous post Mike - only the PSA servers will be able to update software in most occasions - which means a dealer.

This 'going in as another vehicle' isn't going to work in most cases, as the engine ECU will be completely different. Even where they are the same ECU, there are variants of these (the software for a start) to provide certain functionality for certain variants depending on the specific engine variant and the model.

So I can't see this method working - but fingers crossed when the dealer is open you can pass it over to them to sort out. Just be war of what you do in the ECU in the interim - as some actions may have undesired consequences. Do let us know how you get on when you do get it back from the dealer.

If I were you, I wouldn't mention anything about using your clone VCI / Diagbox, as you don't want them charging you to do the job, then blaming your clone if there is an issue that they can't fix.....
