Diagbox DPF Fluid Refill & Reset - How?

[hockinsk]

I've browsed a lot of videos and posts showing how to reset DPF Fluid after filling up, but after 3 hours in diagbox I just can't seem to get past this error in the attached screenshot. This error comes after entering the number of grams i've added to the tank. I assume there's another value I need to add somewhere first such as mileage, but can't find any example of anyone needing this step. DPF Fluid Low Warning came on, drove the car for probably another 500 miles, added 2L of fluid which is ~2000 grams. It's a Peugeot 407 Coupe 2.0 and the DPF Management is done through the ECU it doesn't have a dedicated ECU like some Peugeots seem to have for this.
Any help appreciated.

Check to see if the reported level has gone up, sometimes it says not done, when it actually is! Does it give any guidance on volume? It may be that your number is too big. Also seems a bit odd for it to be grammes, normally it's a volume measurement.

Shouldn't you be resetting the additive counter to zero?

Usually you only add the volume in grammes for the additive when you have replaced the additive ECU on older models with a separate ECU, so that it knows how much Cerine has been put through the actual particle filter.

I've no idea how it works as it doesnt look like any example done by others, but that menu option seems to be asking for amount of additive added in the tank but wont accept any value because it says something else must be programmed first?

I just tried a different way and did this, but even more confused now:

Got the parameters of the PEF and it says I have 470ml of fluid left in the tank. I then go to Aftersales PEF Filter Repair Operation and it asks to enter Total Weight of Additive Contained in Particle Filter. I enter 470g which is the only value it seems to accept (even though 1ml != 1g of fluid imo and there's not 470ML in the filter, that's in the tank. The ECU says the filter has 1496mg of additive in it which makes more sense as has a few hundred km yet before regeneration is gonna happen according to the ECU Paramater reports.

I then go to Personalised Maintenance of the FAP (Particle Filter) it asks for maintenance limit which apparently is 32000km it confirms 0km remaining before replacement of the PEF and says the FAP needs to he changed due to age if vehicle (120k miles doesnt seem to old to me, but I guess if it's based in a maintenance interval of 32000km it is well over now?)

I then go to Personalised Maintenance of Diesel Fuel Additive System and it asks for vehicle mileage in km. I enter that from the dash in km, it asks for gearbox and engine type etc and it then says its not possible to use this function and I need to Apply the mileage maintenance for the additive. But where do you enter that? I assume I need to enter 32000km somewhere as that's the maintenance limit in parameters of the ECU?

[hockinsk]

This is what the ECU parameters are reading:

Particle emission filter load: 62%
Amount of additive in the additive tank 470ML
Low additive level reached: YES
Distance travelled since particulate filter replacement: 65535KM
Distance remaining before replacement of the particle filter: 56250KM

I don't get how the ECU says there's 0km left before filter needs replacing, it seems to ignore the km above? The car has done ~197,000KM

[RichardW]

That's the wrong function, the grammes is the spent additive in the filter. You want repair, then refilling of the particle filter additive ( or words to that effect). By the sound of it you have now told it there 1.5 kg of ash in the filter!

[GiveMeABreak]

Yes, that's likely, only use this when replacing the old style separate additive ECU.

[hockinsk]

I haven't found any menu option under Engine ECU for refilling and the Additive ECU is absent, so I assume it should be under an option somewhere in the Engine ECU, but it might not be maybe? Someone else has said it was hidden under an unrelated ECU on his 407. He advised to go through every ECU in Maintence and then Repair mode until something comes up different to the Filling Additive Tank menu options in Engine ECU. It's gonna be a long day. I can't believe nobody else has had this issue. I've done so much with Diagbox over the last few years but this is unbelievably complicated. Programming 4 new TPMS fro mscratch was easier than this haha!

[GiveMeABreak]

It is generally in the engine ECU section or the repair section.

The problem is that your vehicle shows it could have the separate additive ECU or not.

Please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff.

I can then at least determine the engine type. If the old system with Marwal ADDGO control ECU, then these are notorious at failing when the time comes to top up the additive and usually have to be replaced. But equally you may not have this and the function now undertaken by the engine ECU.

[hockinsk]

Who knows, he said it wasn't where everyone says it is on his 407. I've tried every option in Engine ECU and they all fail either wanting mileage to be entered, something checking in service box or say other Programming is needed.

VIN is VF3**************[VIN obfuscated, can be read by forum staff]

[hockinsk]

At least it still thinks there's ~0.5l of fluid in the tank so I can play with this over the next few weeks until it's sorted as it only does about 300 miles a week.

[GiveMeABreak]

Ok, so you have the DW10BTED4, build date 18th Feb 2008 (RPO 11424), so I would hope it would be managed by the Engine ECU, but looking at my info on topping up, it refers to the separate ECU:

Re-initialisation of ECU

After filling the additive reservoir, reset the total quantity of additive injected from the reservoir to zero in the diesel additive ECU (Computer ADDGO) using the diagnostic equipment.

N.B.: When replacing the particulate emission filter, reset to zero in the diesel additive ECU, the total quantity of additive injected in the particulate emission filter.

This is still nu guarantee that you have the old system though as all this was on the cusp of the changeover.

[GiveMeABreak]

Just run a global diagnostic first and see if it detects the additive ECU.

[hockinsk]

Thanks. It does feel like the options I'm seeing are the newer Engine ECU methods, but it's kind of a hybrid where Additive ECU is absent but it sort of lists the Additive paramaters outside the Engine ECU so might be what this other owner is talking about. I'll get there, just have to be methodical and go through every combination of menu I guess until I find it.
