C4 Cactus 2014 EOLYS tank replacement

[Paul-R]

Have a look here viewtopic.php?t=56452 to see if there's a Forum member with a Diagbox near to you who could help. All are volunteers and some are more experienced than others. Also, if a member no longer has a Diagbox they sometimes forget to notify the Forum.

That’s a joke and he shouldn’t be working there. I would complain about his incompetence, notify Citroen Head Office, leave a poor review of the franchise and go to another dealer. You pay top bucks and expect competent technicians.

They are all suppose to be highly trained and should know these systems inside our. So either he’s new, inexperienced or has yet to be trained, in which case he should not be working unsupervised.

There is NO physical Eolys measurement in the tank.

A diagnostic should not be any more than £90-100

Well, you can't just contact Citroën Head Office. All communication goes through their dealers. I tried calling them directly but they couldn't guide me to a dealer with a good diagnostics guy and just sent me back to the incompetent place I was at this morning.

After some searching it seems easy enough to remove the eolys tank. So I will have a go at that to determine if theres any fluid in it. If it's empty I'll refill it. I can get one litre of Powerflex Eolys fluid for around £30 and see what happens. Bosch tester says it's 97% full already. But if it isn't, then it should work when fluid is added. That's a cheap diagnostic I think.

I've been in touch with Head Office many times. You can make a formal complaint, but you just have to get passed the clueless 16 year old nit on the customer service desk.

As for the tank, be very careful. You do not want to get this stuff anywhere near your skin or eyes. Air can also affect the fluid, so don't expose it and they state that any removed fluid must be safely discarded and not re-used. The tank can only be filled by gravity using a filling kit - you can't take it apart.

I would suggest you get a litre top up (and make sure you use the correct fluid - essential as some fluids cannot be mixed or they will knacker the pump), gravity fill the tank and see how much you get in there. If the lot goes in, maybe try another litre. Then reset the additive ECU (but if it is reporting estimated 97% full that may not be necessary). No need to remove the tank to fill it.

Hmm... but the filler is on top of the tank, not exposed unless you take the tank down. Right?

My plan was to just give it a shake - and of course, take the proper precautions with gloves and mask etc.

Unfortunately I don't have the detail for this vehicle, but the additive tank is generally next to the fuel tank, behind a protective metal shield and looks like this:

Well, Citroen wants an insane amount to diagnose, and their diagnose guy wasn't even sure that my car even has eolys. He mixed it up with AdBlue and insisted that there is an internal level meter inside the eolys tank. He didn't seem competent at all. He would charge me a lot of money and give me a print with error codes which he couldn't even interpret himself. So that was of no help.

I also called the mechanic who had been servicing my car. He seemed hesitant when talking to me about it, as if something was up. I have a feeling that the counter has been reset but no fluid been added. I guess there's no way around either topping up eolys and reset counter again or just fit a new unit and be over with it.

Is there any other Citroen garages not too far away? There must be some PSA specialists in Denmark since small cars are so common.

Sadly im in totally the wrong part of Sweden, otherwise i might have been able to help

Some people get confused by that there is Eolys and Adblue, but they do diffrent things.
Eolys is ther to lower the "combustion" temperature in the FAP/DPF and Adblue/Urea is for NOx emissions

I've never been near a cactus but that tank look pretty similar to other models like the Berlingo etc. The picture of that tank above is upside down so you can't see the filler but yes its on the top of the tank. If its that type of tank then you remove it to fill it, they are really easy to remove. Remove the heat shield first then there are only 3 bolts holding it & it kind of hooked onto some clips on the underside of the fuel tank.

Thanks for that info. That confirms the picture I got when I was under the car the other day. Will remove it tomorrow and give it a little shake to determine whether it's empty or not.

Hi All Sorry if this is not right or the way to do things, i really cant navigate around the site too well

Ive looked on your list of guys willing to help with Diagbox but it wont allow me to contact them.

Any ideas as i dont trust my local Citroen Garage to help me lol

Thanks for your time all

The issue has been resolved!
I confirmed by removing eolys tank that the tank was empty. Took the car to the mechanic this morning. Topped up with 1 liter eolys, program ecu, problem gone. Went for an hour test trive. Still no warning lights or anything.

Mechanic said that previous mechanic set wrong parameters in the ecu so that the car had emptied the eolys faster than it should. That also means that the DPF hasn't been regenerating for some time now. It's 57% full. Will hopefully regenerate now!

I just popped over from the Cactus forum for a bit and noticed this one.

I still need to get my issue sorted but just wanted to ask the educated folks over here a question - would the EOLYS tank be touched during the replacement of an AdBlue tank on a Cactus?

I've posted about it elsewhere but my car didn't have an EOLYS issue, the AdBlue tank was replaced, and now whenever I put diesel in the engine warning comes up until the third time the engine is started. It then goes away until the next time I refuel.

Car has only done 50,000 miles so I'm not sure if it's likely to need EOLYS yet or if the tank / pump is buggered.

The SCR system is completely separate from the Diesel Additive System. They are totally unrelated in operation and have no interaction with one another.

The SCR treats the NOx by injecting Adblue before the SCR catalyst and then the particulate matter is trapped by the DPF afterwards.

You have separate tanks for the Adblue and for the Eolys DPF additive (or a pouch may be used instead of a tank on some models).

Here's a video of the PSA system in operation:



You should have warnings and messages for both system when they need topping up. You haven't been specific in your post about which warning comes up, which light or what the message is. If you ahve that it may help.

Thanks for 6aking the time to reply and apologies for the scant info supplied, I was really just curious if the EOLYS stuff would be touched if the AdBlue tank was swapped and you've already been helpful about this one in my previous post about the Adblue.

To add context though the error on the centre screen is:

"Engine Fault: Have vehicle repaired" and the "SERVICE" light comes on the speedo screen behind the wheel.

Turn off and on a couple of times and it doesn't happen again until you put diesel in.

Despite it only starting after the Adblue tank was done by Citroën they won't entertain just looking at it without £144 for diagnostics which is about the price of a new EOLYS tank if I shop around a bit.

But maybe it just needs filling, it's been looked at previously for a sticky injector so who knows.
