Eolys?

[frer8833]

How many litres are needed, is tank-volume 2.5L? Can 2L fluid be enough anyway by telling the computer that exactly 2 litres were filled?
Is Cerine Eolys Powerflex ok?

Edit: DPF tank volume is 1.5L

[GiveMeABreak]

Use Powerflex.
You don't tell the engine ECU how much fluid you have put it. You reset the counter to Zero.
How much fluid you need is undetermined as the engine ECU estimates the amount remaining. I suggest you get 1 litre and use that to top it up which is the minimum you should add.

[frer8833]

Where is the dpf-fluid-tank, do you have a drawing, so I can refill?
Can the dpf-count be reset by disconnecting the battery (after/before refill)? Or it has to be done with Lexia/diag-computer?

[GiveMeABreak]

No it must be done with Diagbox using a VCI.

The Additive tank is next to the fuel tank, usually on the left side hidden behind heat shielding.

In another forum about Peugeot (maybe relevant for Citroen also) some wrote that they can just reset offline the ECU calculator with Diagbox (with Lexia 3 rev C full chip, I guess) but they can't reset the additive pump offline which can only be reset by a dealer online (connected to the Peugeot server so that Peugeot remotely resets the DPF-pump?). Is this true for my Citroen car also, then there is no need for me to try to reset the additive pump myself?

The link there is all mixed up information because people again are talking about 2 different things! The SCR system for NOx treatment (UREA / Adblue Tank) and the DPF Eolys Additive system, which are completely separate systems with separate tanks that have separate functions.

If your question is about the Eolys Additive for the Particle Filter, then it is reset inside the Engine ECU menu. You will need Diagbox and this can be done offline.

If you look at the video (link below) that was on page 1 of that thread you provided above, the following steps are correct up to this point:

• Run a Run Test by ECU
• Select Engine Management ECU
• Repair
• Service Action
• Work on the Emission Control Circuit
• Filling of the Additive Reservoir (Video Time Index 1:23)

I can't advise of the exact menu after the last step as that video was for an 'Adblue Reset', but it should be obvious and you are looking at something similar to ' resetting of the Additive Counter' or similar. So ignore everything in the video after 1.23 as it is not relevant.

Sometimes there can be further steps or issues that I can't help you with on a Forum, as it depends on your setup, the vehicle and system, but this is generally what you do.

Hello
I am new to this forum, and I would like to ask a technical question.
I have a Peugeot 206 cc Hdi 1.6 110hp from 2005 and I have my FAP tank leaking with the following reference 1500ES which is no more available, I only find a 1500W5. Can anyone tell me if this tank is compatible mounting/connecting wise too my original FAP tank 1500ES?
Thanks

[GiveMeABreak]

Probably not.

The 1500W5 is a multiplexed additive pump which won't work with your vehicle. It's also a slightly different shape.

Is it ok to mix Eolys Extend ('4th gen') with Eolys Powerflex? Is it ok to use Eolys Extend in a Citroen C4 (B7) 2013, which uses normally Powerflex if DPF tank is empty?

[GiveMeABreak]

You must not mix Extend with Powerflex. So no. Use Powerflex or you could damage the pump.

[frer8833]

The Powerflex fluid was filled into the DPF-tank. Low additive error was solved.There is still a fault message "risk of particle filter clogging". Before I drive on the motorway to try to clean the filter, are there more tips I can try, for example adding to the diesel tank a fluid called Diesel particulate filter cleaner (is STP brand ok?) or driving at a lower gear at high rpm on the motorway?

[GiveMeABreak]

This message of course means your particle filter is getting to a high soot limit and has been trying to regenerate the filter unsuccessfully. The engine management system has various strategies for dealing with difficult driving conditions and short journeys, or journeys where the exhaust temperature is not getting high enough. In your case it has not been able to regenerate and the differential pressure sensors are registering higher pressures as the filter continues to block.

So I would not add anything into the fuel tank - it is not recommended as you already have additive in the tank to do a specific job of reducing the exhaust gas temperatures required to regenerate. You either need to go for a good spirited drive where you are not going to be in crawling traffic. There is no need to wreck the engine, just drive at least 40 MPH / 65 KPH or higher and keep in 4th gear for a while to get the engine temperature up as soon as you can. The engine management system will detect the driving conditions and attempt to regenerate the filter as soon as conditions permit.

If you have Diagbox then you can force a regeneration as long as it has not been disabled by the engine management ECU in order to protect the engine.

If the message does not clear, then your filter may indeed be past the ability to regenerate if it is too full. When it gets to anything over 70% regeneration may not work, and the filter will need deep cleaning / replacing.

I always think it's important to know what mileage the vehicle has done. Generally speaking, the Eolys will need replenishing before the FAP needs replacing / deep cleaning. Perhaps twice in the time before the FAP clogs up.

[frer8833]

Limp mode was activated while driving 10 min on the highway because of the fault 'risk of clogging DPF-filter'. I can still drive ok manually with gear pads. If I successfully manage to clean the DPF-filter by driving for hours on motorway will the ECU still not take Citroen C4 out of limp mode, is it a fault code unresolvable by DPF-regeneration?

Is Forced DPF-regeneration with Diagbox (I understand it as DPF-filter is not removed for cleaning, it is still inside the parked car) better than Active DPF-regeneration (driving on highway)? Maybe the filter needs being taken out for harsh cleaning?

[Paul-R]

Mileage?
