Resetting Eolys counter with diagbox

[Rappy]

No that's not what I'm saying.

I'm not sure what you are referring to but you may have taken something I've said out of context.

The additive tank has NO physical measurement gauge. It is estimated using variables by the engine ECU. So if you fill the tank up regardless of 1 litre (this should always be the minimum amount) or 3 litres, - if you do not reset the additive counter to zero the ECU has no idea you have filled the tank.

Since the additive tank has no physical measurment gauage and you can only reset to zero, how does it know you filled with 1 liters or topped it fully (let's say at 2 liters)?
In my world, you need to top it fully as this would be the reference. Or am i wrong?

The actual wording and function varies from ECU to ECU - sometimes the function just says 'filled the tank' and it resets to whatever the default value, sometimes you have to enter an amount filled, sometimes you have to do it in more than one place. If the amount showing doesn't match what you put in, some ECUs have an option to change the configuration and update the amount in the tank. on most cars the usage is around 1 litre / 100000 miles so if you put a litre in it will almost certainly outlive the car even if the actual amount doesn't match what the ECU thinks is in the tank!

Exactly and furthermore, the tanks are rarely filled at the factory to capacity! The tanks are often higher capacity than the stated amounts. Ie 1.4 lt can actually take 2 litres.

The point is that whichever way you have to reset the additive counter, you have to perform this operation for the ECU to recognise the operation has been done. It still calculates the amount of Cerine that has been put through the filter from the number of doses injected, used for partial determination of the life of the particle filter, but that’s another story.

Hi, I just topped up 1L of powerflex additives and run into an issue to reset the Eolys using Diagbox software. Been reading through different threads in the forum and I understand from Marc that the reset has to be done via the ECU mgt. My car is a 2016 C4 Picasso 1.6BlueHDi.
Using Diagbox 9.186 from (psa-diag.fr/diagbox/) and I have a version C Full chip VCI (missing 10k resistor). I am able to run Global Test, and saw from the exhaust line information that the additive level is 141ml and decided to top up 1L powerflex. The additives pump system is PADDGO_INERGY.

Tried to go under the repair menu, pack repair,, under replacement parts OR Service Action and look for "Filling up additives" but I cannot find there.

Tried going to repair, pack repair,, service action, Draining-Filling-Bleeding, there are "Filling of the additives" & "Prime the additives circuit". I tried to Prime it, it failed. I tried Filling of the additives it asked me to do the actuator test first.Which I assume is to Prime the additives. (I have recorded a video for this)

Tried search around under Repair, Maintenance, Fault Finding, I dont see a reset counter function for the additives.
What esle am I missing here? Am I using the right software?

[GiveMeABreak]

Those are the correct locations, but your 'full chip' may not be a full chip if it doesn't have the resistor.

[LeL]

So I supposed the section on Draining-Filling-Bleeding is correct, that's where I need to Prime it first?
U mean that missing 10K resistor doesnt allow it to prime?

Can I just leave it with the service light on with error code? What will happen if I dun reset it?

[GiveMeABreak]

1) No, you tell it that the additive has been refilled first by resetting the additive counter to ZERO, then the priming operation is initiated after this.

2) All I can tell you is that the 10k resistor was always present on original VCIs and decent clones and could affect communication with some systems.

3) If you don't reset it it, or it fails to reset, the Engine ECU has not way of knowing this has been done (there is no physical measurement), the warnings will keep appearing, and at some point it may prevent assisted regeneration. If this happens then the DPF may start to clog more frequently and when that happens the engine management system will start reducing power to prevent engine damage from blockages.

If your system can't reset it, you're probably better off just getting the dealer to do it for the cost od a short diagnostics session.

Is there anyone in or around the Merseyside area with a digibox that i could visit to reset my Eolys counter ... Im topping it up this weekend after a notice it was at a critical level..

Thanks in advance

[LeL]

Thanks Marc for the explanation. The 10K resistor is very important. Without the 10k resistor I cannot even reinitialize the additives in the pump.

Update: I found someone to help me solder a 10K resistor onto my VCI connector and now it become a Full Chip set.

Using Diagbox 9.186 from (psa-diag.fr/diagbox/), I managed to reset the additives.
1) Run Global Test
2) Select ECU Engine Management
3) Repair
4) Pack Repair
5) Action Service
6) Draining - Filling - Bleeding
7) Refilling Additives Diesel
8) Follow the instructions on screen (U will need to switch off ignition twice for 30 sec)
9) Re-initialisation successful

10) Run test again check Exhaust Information 1 to see what is the volume in Additive pump

There is no more error codes!

[Richip76]

Glad you got it sorted LEL. wish you were closer to reset mine....

Great news, thanks for the update and glad you're back on the road again.

has driven almost 300km over the weekends and everything is good. No error codes, no engine light, check and found nothing unusual.

... I wish I can help you...

Morning. Hope you’re all having a good weekend.

I’m wondering if anyone has bought one of these.

https://www.ebay.co.uk/itm/175689570282 ... media=COPY

LEXIA 3 FULL CHIP REV C DIAGNOSTIC INTERFACE PEUGEOT CITROEN DIAGBOX PP2000 UK

Harder to place fake reviews on eBay than Amazon. And just wondered if anyone has purchased one of these to reset Eolys after top up.

I emailed the seller and asked

??..
Im interested on one of these... I've checked my laptop and as per image it is set up to act as a virtual machine.
My question is Ive a Citroen
C4 Grand Picasso 2016.
I'm looking for what i need to reset a number of counter mainly the PAT/Elouys counter after the take has been refilled.
Is this somthing I will be able to do with this..
Bt all account it looks like I will I'm just looking for some reassurance

They replied this morning with

Good morning,
As this is a dealer tool, it will do the job you require. Many have purchased this kit to do this particular job. They all seem to have done the job without any problem.
One thing to remember is, bsi configuration on 2015 on wards vehicles, requires servicebox online, it costs £40 for 24h access.
Not saying you'll need this but, you might on some tasks.
Eolys reset might not need servicebox online though.
Regards

Anyone have any thoughts.

[GiveMeABreak]

That's correct. You need a full-chip kit and this appears to state it is, and is priced at about the level I would expect for a full-chip kit.

You WON'T need online access to reset the additive ECU - this is a maintenance operation, not an ECU configuration.

Make sure you don't use the laptop for anything important, as this can be a messy installation - always best to use a dedicated Diagnostic laptop.
