Hi,
Just 2 quick questions. Why does a diesel engine need an additive?. My 1.9 TD runs quite happily without it. And why is it ever £90+ per gallon ?
Who is taking who for a ride.
Greg

To meet current emission rules, just as in days gone by diesels ended fitted with EGR systems and petrols 3 way catalysts. The additive lowers the 'burn off' temperature of the soot created by the combustion process which is then burnt off in the particulate filter when the ECU thinks it needs to.

Im not sure if i believe the 'to meet current emissions regs' or not.

There are two versions of the 1.6HDi offered in the facelifted C5, one has a FAP and the other doesnt (Design trim level). Every figure is the same, c02 is the same for both, as is economy and performance.

The 2.0 110 hdis dont have them and they never smoke from the exhaust and have cleaner emissions than the 2.2 with FAP.

Its just more hassle and costs, id rather not have a FAP system.

Can it not be removed or disconnected somehow?

That's a bold statement! BUT on the basis that it is a smaller engine less power etc. one would expect the gaseous emmissions to be less however one area where it will be far dirtier than the 2.2 engine with a FAP is particulate emmisions i.e black smoke aka carbon. Carbon particles is what the FAP traps, if you have one in terms of particulate matter you will be cleaner than if you don't.

Its just more hassle and costs, id rather not have a FAP system.

Removal has been discussed to death both here and other places and I doubt that a FAP will be optional on anything for much longer
so best get used to it.

I will second citroenmad with regard to the C5 emissions.
I have no FAP/Eolys and no smoke either, emmisions are very low.

[jimleshed]

Hmmm. Mine has just started this.
Switch off, eolys pump runs for about 2 mins, then stops.
I have had the low warning for some time, although the fap tank is filled.

But, I have just got my Lexia working, and tried to reset the eolys counter thingy, which is probably what caused it. Too late tonight to investigate more.
My plan was to reset all faults, the see what happened after a few days of running....
Did you ever get a resolution to this problem?
I'm going to look at mine some more at the weekend...
Cheers

Thanks for the explanation, Steve.
We have a number of hired tractor units with us at the moment, - all using AD BLUE. An oil additive to probably do the same job as Eolys fluid. Just wondered if anyone else here has heard of it, and if any price difference to ely juice.??
Greg

[myglaren]

AdBlue is completely unsuitable and incompatible with the EOLYS/FAP system.

AdBlue is made from urea (it is extracted from cow urine) while EOLYS is made from Cerium.

Wigglywoo, I had this problem yesterday after playing with a Lexia to reset my Fluid level. Switch off, eolys pump runs for about 2-3 minutes.

This evening I disconnected the battery for 2 hours - hey presto, when i reconnect all is fine. No pump running on switch off, no low additive warning. Next I'll have to check that it actually does pump when I fill it up, but looks good at the moment.
cheers

Hi,
My son bought an 05 Cit C5 VTR with the 2 litre 138 bhp motor in it. Does this car use Eolys juice ?. Cant find any tanks for the stuff anywhere, so assume it doesn't.

When I got my car back from service centre, they told me the screen was still showing Diesel Addative Min Level but it has not shown this since I got the car back At beginning of May. I just have the problem with the pump running after I switch off.
I disconnected the battery overnight , when I got the car back, to no avail, do you recomend I try this again?
Thanks

[jimleshed]

HI Wiggley, all I can say is that it worked for me, and as mine was a similar problem it was worth a try. (pump cycling after switch off, after someone had reprogrammed Eolys ECU)

It wont do any harm to try again, all you lose is your radio settings!

What year is your car? Mine is a 2001 51 plate 2.2

A sudden thought wiggley.
I seem to recall a specific routine you can go through after fluid top up. I'm sure someone here will have a link.

Something like (but only from memory)
Top up tank (more than 10 Litres)
run engine for 2 mins
switch off for 30 secs
open/close filler cap
restart engine.

NOTE - this is only from memory, I'm sure the correct routine varies by some important little detail or is more complex, so best to find out exactly what it is. Someone here may be able to cut and paste it in!

hi
i have a 02 2.2 hdi and it has started to do the same you can hear a pump running ,i thought it was the pump in the fuel tank so i disconected the supply ,but i could still hear a pump so it must in eolys pump which carnt be good pushing more fluid in than it should be ..is this pump easy to get to ?never a dull moment with these cars
cheers
dexy

[jimleshed]

when does the pump run dexy? when ign switched off? and then for a minute or two?
if so it sounds like Wiggleys and mine!

hi Jim
yes turn the engine off then it starts up and runs for 2-3 mins it doesnt do it every time the engine is turned off just now and again ,i thought it was the pump in the tank so i lifted the back seat removed the black cover and discontected the supply to the pump but could still hear a pump running .i can turn the ignition on the pump stops as soon as you turn it off it starts again
its only started doing this about 2 months ago
only thing that concerns me it must pump all the Eolys fluid into the tank which carnt be good .
so is there any cures out there .apart from pulling the fuse every time it starts running
cheers
