Particle filter additive

[Buttwad]

I have a 2012 DS5 D- sport 2.0 and today had the error ' particle filter additive level low'
Have to excuse my ignorance here as this is new to me. How do I fill it up? What do I fill it up with? And is there any advice anyone can offer regarding this.
I've read posts about ad blue and a filler cap in the boot. Is this what I need?
Thanking you in advance for any assistance offered.

It's probably a reference to Eolys additive fluid - this isn't designed to be topped up by the user themselves, so you may wish to contact a dealership to get them to do it.

(It's possible to be done yourself, but someone else would have to chime in as to the exact parts and instructions to do so, may require a lift?)

You will need the correct additive (as mixing dis-similar additives causes all sorts of problems), and access to the Lexia equipment needed to reset the additive counter (the system does not have a level gauge; it injects a fixed amount in when needed, so has to be told when the additive has been topped up).

Ad-Blue is a different chemical, and is managed differently as well. There is normally a level gauge of some sort, so when it drops below a certain level you get the warning messages.

I'd be surprised if a 2012 vehicle had AdBlue. For one thing, it's normally reflected in a model's name somewhere - e.g.'BlueHDi' or similar.

Forget everything related to Adblue above. Your DS5 won't have the SCR system for this year.

You will have a Diesel Particulate Filter that traps all the microscopic harmful particles in the filter and burns them off periodically, which is referred to as regeneration.

Assisted regeneration of the particle filter is achieved through a special Eolys additive. This is stored in a separate hidden tank, near the fuel tank, which meters out a very small amount of the additive into the fuel tank each time fuel is added. The purpose of the additive is to lower the exhaust gas temperature required for regeneration, from 550 °C to about 450 °C, at which point the soot and particles combust and are converted into ash.

In order to advise you of the correct additive type , please post your VIN up (automasked on post submission) as additives have to be the correct type for the system employed on the vehicle.

Spoken to local dealer, who want the pricly sum of just shy of £400 to top it up, so looking to source the Eolys and get someone else to do the work and sort the ecu.

According to your VIN it should be Powerflex.

Cheers.

Now to be a right pain, anyone know how much the tank holds and a good place to buy some powerflex?
Thanks again.

You can buy it in 1 litre or 3 litre containers with or without a filling kit. It needs to be gravity fed until the tank is full (the quantity remaining is not physically measured, it is estimated), so it generally filled until it starts to back flow.

You will also need a professional level diagnostic tool like Diagbox to reset the additive level back to zero within the engine ECU or you will continue to get warnings and the system will not know the additive tank has been refilled. A dealer will do this at anywhere from £150 to £300 approx. depending on how much additive is used.

Thanks guys for all the advice. Last little question (I hope) is do I have to fill the tank to the brim, or can I get away with putting 3 litres in?

[GiveMeABreak]

It is important to fill the tank, so when resetting the additive quantity, the engine ECU can undertake correct calculations knowing the tank is full.

The fluid is generally cheaper in larger quantities, but once opened it cannot be kept on a shelf. You may not get 3 litres in, so your choice really as to whether you buy 3 x 1 litres packs or 1 x 3 litre, knowing that you could end up wasting a lot of fluid if it does not take the 3 litres.

I've seen this quoted before and I have to ask why? If you think about it, the Eolys fluid in the tank on the car stays in there for years on end. My 2013 C5 has fluid that is now nine years old. Also, we are not told to evacuate any old fluid when putting new fluid in.

[GiveMeABreak]

I can only pass on what PSA state concerning this:

• Use clean additive only as any particles risk causing the additive injector to seize
• Do not re-use any additive bottles that have been opened (single use)

I suspect once opened, storage can lead to contamination.

The filler union safety valve provides:

• Sealing function (prevents evaporation of solvent, ingress of dust, mud and water)
• Damping of overpressure
• Set to atmospheric pressure

Is the powerflex Eolys for my car 9736 A1?
Cheers again chaps.
