Eolys?

[wurlycorner]

Thank you very much Marc, that's fantastic.
I shall investigate!

Thank you very much Marc, that's fantastic.
I shall investigate!

Just to follow up as I'm doing prep work, marking up the wiring diagram... I can't find the following components in the components list, that are on that schematic:
1383 (going on symbol and description for 1385, I think this is another Cat/EGT temp sensor, but where in the system?)
1384 (going on symbol and description for 1385, I think this is another Cat/EGT temp sensor, but where in the system?)
1283 (going on the symbol in Driver Information component table, I think this is the low fuel level warning light on the dash?)
BPCB (F02 is obviously a main fuse and won't be linked to my problem, but I'd still like to know what BPCB is please, for reference?)

Could you possibly confirm what they are please, or add them to the components list?

Beyond that, I can't see the additive tank is part of this circuit - and I can't see anything listed in the components list that would match it, either?
1341 is the DPF pressure sensor; 1211 is the Fuel Gauge/Pump and the remaining components on that diagram are the battery; ECU's; fuse box; and Ignition Switch.
So is there another relevant schematic for the additive tank please?

EDIT: This post earlier in this thread suggests there is a fuel additive ECU and this is component number 1282 and the pump is component number 1283.
There isn't a 1282 on that circuit for my vehicle, but although that post was also for an X7, it was a 1.6 rather than 3.0 - so it's possible that the 3.0 doesn't use a separate additive ECU of course (though interestingly the additive tank is the same part number as for mine).
But either way I'm still slightly at a loss as to whether 1283 on my circuit really is the additive pump - it is a four pin connector (which looking here I believe the additive pump is, in reality - so that kind of tallies in that it shows utilising pins 4 and 3 of the connector?) but the symbol is throwing me off as noted above - and it shows only 2 pins used of component 1283 where the real component has 4 pins and the pin-out in the earlier post suggests 4 (of 6 in that instance) pins are used - which would mean the schematic is missing two pins/wires???
Could you possibly have another look and confirm please, Marc?

Thanks

EDIT again:
Looking more closely, the pic of the connector on the new tank does have space for 2 further pins and the pin-out in the previous post shows only 4 of 6 pins fitted, with pins 5 and 6 being for a level sensor that are connected but not used, with pins 3 and 4 being those that operate the pump as a duty cycle.
That could match the latest schematic in theory - pin 1 and 2 are never fitted and the 3.0 doesn't even bother with a connection to pins 5 and 6 (the symbol for component 1283 completely throws one off, however)?
However it still doesn't match completely - the previous posts says pin 3 is RCO signal and pin 4 is earth.
On that latest diagram, pin 3 is fed from the fuse box (so will be a straight 12v feed) and pin 3 goes to the Engine Management ECU.
That would mean it operates as a a ground-side switched duty cycle, via pin 4. Entirely possible, but doesn't match the earlier pin-out/operation description.
I guess I can investigate that on the car tomorrow, but if the other unlisted components can please be checked/listed and could the pin-out for that component on my car also be checked/verified, please? That would be very much appreciated.

EDIT yet again;
All diagnosed. It is the pump, I'll do a separate thread on the diagnosis when I have the new one done, in and tested. The existing tank is full, so in theory I could transfer the fluid across to the new tank, but I don't want to risk contamination etc for the sake of £65... I've ordered this fluid with the tank, which it says is the right one for my car - unless anyone is sure not???

Haven't had time to read through all of your recent post as I've been dealing with 60 posts Iain, but for now here are the missing components (and the list updated). I'll answer the points as I have time.

1383: Upstream exhaust gas high temperature sensor FAP
1384: Catalytic converter with exhaust gas high temperature sensor downstream of the precatalyst A
1283: Fuel additive pump
BPCB: Battery Cable Protection Unit

1283 is the fuel additive pump (lower right) and one of the components not on the list. So it is on this diagram.
Pin 4 (wire 1285F) is the engine ECU control wire for triggering the metering and Pin 3 (Wire 1284F) is the power supply from the Engine Fuse Box.

The other diagram you refer to is for an entirely different engine management system (1.6), and the fuel additive ECU is not present on this vehicle. This operation is entirely handled by and incorporated into the engine ecu, so is not relevant here.

• Not all pins are used
• There is no fluid measurement device - the additive tank quantity is estimated by the Engine ECU (which is why the additive counter must be resetin the engine ECU when the additive is topped up.

Thanks again Marc.
I've updated my previous post again - I think our updates crossed. All tested and new part ordered.

Hi all, I have a 2016 Citroen berlingo van, bluehdi euro 6. I have a power flex tank for the eolys fluid and was wondering because there are so many fluid types to purchase online. Found some from Poland, 3 litres and it’s suspiciously cheap is the ‘storm’ one correct for my van?

Thanks
Peter

Powerflex is the additive name not the tank.

Best you provide the VIN so we can check fluid type.

You need Eolys EXTEND

[malc4]

Is eolys that important? I've seen one of Jimmy's (the DPF specialist) vids where he deleted the eolys system (setting to absent) to resolve eolys faults that he couldn't remove. Also my friends 308 1.6 has anti-pollution messages with eolys pump errors but the car seems to be regenerating ok with low dpf pressures...

[wheeler]

The problem is you wont know for probably quite a few thousand miles if its an issue & i’d say it would also depend on your driving style

[malc4]

Thanks, makes sense that passive regen over long drives would keep the dpf clean, although at higher temps due to lack of eolys? Maybe that's why she had a 'mushroomed' injector tip a while back? I like the idea of keeping a syringe of eolys in the glovebox to add manually at each refill;)

[Pawel83]

Hi all,
I am a new on this forum. Can someone confirm what type of Eolys fluid my car requires please? VIN is VF7**************[VIN obfuscated, can be read by forum staff].
Also, does anyone try to Launch CRP129 EVO to reset ECU or can you recommend any other diagnostic tool?

Thank you

Hi I'm new to this forum. My c4 gran picasso has recently started with the d filter low level error. I have searched online and it took me to this forum. My question is what type do I need for my car. And how would I go about topping it up. Any help would be greatly appreciated. Thanks

I ran the car on a motorway having filled the tank, for about 20 mins at a constant 90km/hr , the error is still coming on shortly after I start the car , and it jumps from A1 to M1 , so it looks like it's the pump /tank unfortunately . I dropped into the nearest Citroen main dealer , they said they couldn't check on the recall but they'd call me back later ....I'm still waiting

My car too, Citroen C4 II, B7, 2013, started to switch from A to M (automatic to manual) when starting car and accompanied by a beep and Engine Fault Repair Needed display text. RPM is limited to 3K. I think it is caused by the planned obsolescens error which is triggered by how many times you have fueled your car or opened the fuel cap, which is p1445 error code. It says DPF is old and need replacement even if DPF is good and it is ok in my case. It also turns off the eolys pump like a domino effect. Eolys level is also ok, no low eolys error code.

So I consider doing what the mechanic does in this video to get my car out of a lowkey version of limp mode.

These are the error codes triggered by "DPF-is-old-bogus-error": "P0EB0 Additive reservoire empty fault", "P1434 Multiplexed additive pump. Pump fault.", "P1445 Additive adding. The quantity of injected into the particle emission filter has exceeded the maximum threshold. The particulate emission filter must be changed.", "B1811 Fault on the diesel additive pump". P0EB0 is fake error, Eolys is not empty.

So with the right scanner I will look at the DPF-replacement teach-in, this tells the ECU that the DPF is replaced because if P1445 is already triggered it is too late to use DPF-reset to reset the 'P1445 timer', which tells the ECU that the ash-level counter is reset to 0%.

Can you help me, i dont know what type of Eolys I need for my Peugeot 508 1.6 BlueHdi 88kW, 2017. One service said POWERFLEX, the other said EXTEND? My VIN: VF3**************[VIN obfuscated, can be read by forum staff]
