Re: Resetting Eolys counter with diagbox
Yes but that warning was from before you did the reset properly. Since then you say that you have only had the "Risk of particulate filter clogging" message. I still think that you need to get a back-pressure reading.
As I get older I think a lot about the hereafter - I go into a room and then wonder what I'm here after.

Re: Resetting Eolys counter with diagbox
There is NO level sensor at all. Fluid remaining is calculated by the engine ECU purely from distance travelled and quantity of fuel added.
The fuel is measured before and after he engine is stopped and in some cases a fuel filler plug detect harness may be fitted to help determine if any fuel might of been added. But the calculations are done by the engine ECU and the quantity f additive is estimated.
The wiring is the metering device.
You have 2 issues going on. The DPF is getting clogged due to a lack of additive fluid OR the ECU has stopped regeneration taking place because it THINKS the fluid is too low.
So regardless of quantity of fluid if you don’t reset it properly regeneration will cease (backup mode) warnings will come on and filter will soon get clogged. Don’t continue driving it if possible as if the clogging gets anywhere from 75% or more it may never be able to regenerate and will have to be deep cleaned.
Again, it would help if you could post some screenshots of the screen menus and options as the reset should be to zero according to data I have.

(2) is the Additive -adding pump

Re: Resetting Eolys counter with diagbox
Thanks everyone, I will have to get this sorted.
I'll drop the tank and check there's fluid, I'll check the back pressure reading (If I can find it) and i'll take a video or screenshots of the diagbox screens.
Marc, my tank doesn't look like that and it doesn't attach to the fuel tank.
Thanks again.

Re: Resetting Eolys counter with diagbox
These are the components of your System and how it works:
Key:
"A" Electrical links
"B" Additive under pressure
"C" additive
"D" Diesel
Role
The fuel additive function keeps the particle filter operational by aiding the combustion of the captured particles, performing the following actions:
The engine ECU receives the info on fuel quantity put into the vehicle via the BSI, using:
The engine ECU records in memory the weight of additive that is accumulated in the particle filter.
Note: The additive fluid is Cerine-based. Cerine is non-organic and cannot be burnt off in the filter. It is this element that gradually leads to the particle filter needing replacing or deep cleaned.
If the filter has already reached the stage where regeneration is ineffective or not occurring, then it will also lead to soot clogging, requiring cleaning.
The engine ECU authorises or prohibits the applying of additive, as a function of the following parameters:
The BSI receives the following information from the engine ECU :
The engine controlled ECU controls the fuel additive pump when the following conditions met:
Key:
"A" Electrical links
"B" Additive under pressure

2 | Built-in systems interface |
3 | Engine ECU |
4 | Fuel tank |
5 | Fuel gauge |
6 | Fuel additive pump |
The fuel additive function keeps the particle filter operational by aiding the combustion of the captured particles, performing the following actions:
- Lowering the temperature of combustion of the particles to 450°C (instead of 550°C)
- Impregnating the particles that are gathering in the combustion chamber
- Spreading the combustion of the particles
The engine ECU receives the info on fuel quantity put into the vehicle via the BSI, using:
- Fuel gauge
- Wheel speed sensors
- Determines the quantity of additive to be injected into the fuel tank
- Controls the fuel additive pump

Re: Resetting Eolys counter with diagbox
Thanks, I was expecting to see something about a sensor on the fuel cap.
Maybe not all models have one, I've not looked to see if mine does or not.

Re: Resetting Eolys counter with diagbox
I wouldn't get too hung up on this - if it was faulty, Diagbox would throw an error up anyway.
It is not essential - it only is used to help the engine ECU determine if fuel MAY have been input - not that it has. Vehicles with a fuel filler detection flap may just inform the BSI to do a full fuel check in case fuel has been added or not. Again, the fuel tank measurements is not always measured from the sender - it is estimated from quantity last measured, distance travelled and every so often takes a real measurement and adjusts - so the fuel flap sensor (where fitted) just tells the BSI to do a full check.
from what I can see you don't have one fitted anyway.

Re: Resetting Eolys counter with diagbox
Today I managed to spend some more time on this.
I started off by dropping the tank to make sure there was fluid in there.
There was plenty of fluid and no signs of any leakage.
I did think I might have found a problem as the connector wasn't clicking into place properly due to the protector around the wire.
I sorted that out but unfortunately hasn't made any difference.
I then tried resetting with Diagbox, again, no difference.
I have made a video of me going through the process which is taking ages to upload.
One thing my wife has picked up on is that the warning always goes off when we're going up a hill.
I'm wondering if I put too much fluid in (2lts) and whether this is causing a problem.
I'll post a link to the Diagbox video when it's uploaded.

Hopefully, this link will work.
The dash lights don't flash like they appear to in the video.

Re: Resetting Eolys counter with diagbox
Mick, what you are doing in the second part is wrong.
First things first. Always allow the Global Test to finish, don’t interrupt it.
You did the first part correctly.
Where it then told you to perform the same test again, You went to the Injection ECU correctly, but selected the wrong option.
You went in under replacement of the particle filter, and the to the bit where you tell it how much is in the tank. This is only where you have replaced the actual filter, which you haven’t.
You needed to go into the same option as you did before PACK REPAIR and then repeat the process you did before.
Because you have now changed other values, you should switch off and leave the car for a bit before starting again. This time only follow the procedure as you did in the first part, but in both the additive pump section and the engine ECU section.

Re: Resetting Eolys counter with diagbox
Thanks, but I'm still unsure what you mean.
I'll have to watch the video again just to see what I did.

Re: Resetting Eolys counter with diagbox
What should I select at the screen at 4.24?
Is that where I went wrong?

Re: Resetting Eolys counter with diagbox
Hi Mick, exactly there at that time index. Go into replacement parts instead and repeat what you did in the first part, but make sure you do them in the same session. ![👍](//cdn.jsdelivr.net/gh/twitter/twemoji@latest/assets/svg/1f44d.svg)

Re: Resetting Eolys counter with diagbox
Well, I got up early and tried again, no luck ![Sad :(](./images/smilies/icon_sad.gif)
The warning popped up again on the way to work.
The video of the procedure is uploading.
Either I'm still doing it wrong or something unrelated is causing the warning, maybe the DPF itself.

Here's the video, I think it's time I try what Paul-R said and check the DPF itself.
