Eolys fluid?.

Does anyone know if this new model still has the eolys system, or is the diesel fuel used as a substitute now?.

The BlueHDI engines do not use Eolys, but AdBlue. They're two different liquids.
Yes the new 3008 does have eloys. Page 300 in the hand book

Pretty sure it's not Eolys but AdBlue instead. Eolys was used in the older PSA cars.

Manual page 303 is titled "AdBlue® and SCR system for BlueHDi Diesel engines".
Eloys is for particulates (soot) and Ad blue is for Nitrogen Oxide. Two different toxins you get from the exhaust systems of diesel engines.
I'll have a look under the wife's car later and see if I can see..
Oh bottoms!
It looks like it is still used....as a DPF cleaner.
Is it a supplementary system in addition to the usual 'regeneration' method using diesel fuel?.
It's a totally different system. The adblue is injected/spayed into the exhaust system and neutralises the NOx.
The eloys is in the Diesel and helps clean the PAF.

Ah!
So it's diesel PLUS eolys fluid for the regen?.
Yep sure is.

The adblue makes the diesel engines "Euro6" compliant.
The Eloys helped make them "Euro5"

Load of bull sh*t really what with China, India, North & Latin America and others polluting wholesale.

Yeah, I understand AdBlue - NOx - catalyst
But
Eolys - DPF .....in ADDITION to diesel for 'regeneration' ?
Other manufacturers don't use eolys for DPF regeneration, (they just use diesel) so why do Peugeot?. :confused:
This may explain why other manufacturers have far more issues with DPF regeneration not being completed and warning lights appearing, than the PSA group do.

My 'limited technical understanding' (and certainly was the case on previous PSA models) is that when the fuel cap is opened on our diesel cars, a dose of the Eolys is injected into the system. The Eolys liquid pouch does eventually require replacement as original Xsara Picasso owners know all too well.

I never experienced this problem myself on one of my previous cars, a 3.0D Jaguar XF, but other forum members were getting orange DPF warning lights, requiring an 'Italian tune-up' when they didn't do enough miles to complete the DPF regen. I always made sure I went the long way to work, to ensure I didn't get any troubles.

I think the PSA group cars don't seem to suffer anywhere near as much, perhaps because of their technology and the Eolys.

If the eolys system improves the lifespan of the DPF then it's probably worth the added complexity I guess.
To be honest Nagaman, unless you do mega miles like I do, you probably wont have to worry about that stuff for quite a while.
I guess average miles before having to refill the eloys would be in the region of 80k miles. (128,000 kilometers in your money). I normally get over the 100k but then I do a lot of motorway stuff.
The dealer will tell you it needs filling around 80k but you should wait until you get the warning message up on the dash. I've been told one needed filling. 40k miles later I got the message on the dash.

The biggest issue for me is the Adblue sh8t. When you buy a vehicle they don't tell you that you'll need to put 20 litres of pigs p*ss in your vehicle every 7,000 miles @ a cost of £26. That adds 0.37 pence a mile to your running costs! That works out to £222 per year per vehicle. Bloody tree huggers cost me a fortune!!

I thought Peugeot/Citroen sold a 10 litre topup of Adblue for about £10? That is a fixed price for them to fill it as well.

I've noticed its also appearing on supermarket shelves now as well.

Nice to see the adblue top up is now next to the diesel fuel filler. My C4 Grand Picasso was hidden under the floor, requiring emptying of the boot to get to it.

We'll probably be doing 30,000km/year being fancy free and a wide brown land:)
but being an economy driver I'll probably get fairly mega distance from a fill.

Is it true the fluid goes into the tank based on the frequency of removing the fuel cap?. If so, do you avoid keeping the tank topped up. I would love to get some sort of published info on exactly what goes on........I don't like the mushroom treatment :D
I've always made sure I never just top up diesel in small amounts, to ensure the liquid lasts a lot longer.

See:

DPF additive system? - Citroen DS4 Forums

There are lots of articles online about how the Eolys works, but yes its based on fuel top up. More small top ups would mean it is used more frequently than full fill ups.

C4owners forum have a great FAQ on it. I'm still a Premier member, so I'm not sure if you can read it without being signed up:

Thanks for all that good work:thumb:
I shall devour it at leasure:)
According to manufacturer guidelines, an EPF-equipped diesel engine is likely to clog up unless it is operated at 50mph for at least 20 minutes, or covers 50 miles at motorway speeds at least once every couple of weeks.
So a minimum of (50/60 * 20) = 16 miles at 50mph for the filter regen and to keep the DPF healthy.

Our shortest shopping trip is 30kms so mine will be like a pig in s..t.:thumb:

I still wonder why we are discussing Eolys systems here when the Peugeot 3008 SUV will not have one.

From the link posted above we can see that even in C4 2.0 diesels they stopped using the Eolys system some time in 2013:
Important Note: 2013+ 2.0 HDi engines fitted to the C4 Picasso range use 'Adblue' and not Eolys additive in the DPF system.

Here's a good video on how the emission control works in the BlueHDI engines that the Peugeot 3008 can be equipped with.
