It is the dreaded Eolys fluid.

You can refill the tank yourself and it isn't too difficult, a bit awkward though.

Info from Honest John

More

It is a Cerium based fluid that reduces the temperature that the soot burns at that is caught in the particle filter. A small amount is injected into the diesel tank at each fill-up. The ECU measures the amount of diesel put into the tank and dosed out the appropriate amount of Eolys fluid.
Allowing the tank to become depleted is quite bad news on some models, needs the ECU replacing.

The Eolys fluid is expensive, currently around £38/L and the tank takes four litres. The particle filter often needs changing around the same time so watch out for that coming.

There are two types of Eolys fluid too, make certain you get the correct one.

Don't be talked into using the commercial wagon stuff - Blue somethingorother, it is completely different and incompatible, urea based, reportedly extracted from bovine urine, as close to BS as it comes :)

You will find some more info on this forum if you can be bothered to trawl through it.

Out of interest, how many miles has your 1.6HDi done to warrant a eolys fluid top up?

The problem as I see it with the Eolys fluid is that every time you open the fuel flap, you inject a small quantity of Eolys into the system, now if you are a fill it up until empty chap you will make the most of the fluid in the tank, wheras if you open the flap and put a tenners worth in every couple of days, it will not last very long at all.

The system is supposed to take note of how much fuel is added to the tank and deliver a proportionate amount of Eolys.
Could be a fault in the system and too much Eolys is being added to the diesel.

Ah right, probably is due for it in that case. Im told usually around 70-80K is the norm for refilling this?

Hows the 1.6 at 101K miles? Im quite interested, still going well and good on fuel? Had any problems?

One bit of advice i would give, is frequent oil changes, as the 1.6HDi can suffer turbo failure if the oil is left for too long.

Id like a facelift C6 1.6HDi, so im interested to hear what you think.

Hi Chris , only had it about 6 mths , great towcar, think w/bearing on the way out was like that when I bought it at auction . It's a one driver company car and as I got it for 3k with new tyres and 11months MOT I guesss I'll have to spend some money on it .

what i understand is the earlier systam has a float in the tank to indicate when low/empty, and the later system has an electronic counter,

if you catch and top up the float type system before the warning comes up, you should get away with haveing to have it pluged into a LEXIA to re/set,

were as the lecy counter system dose not allow this opption,

also i belive if required the filter which is in the exhaust forward of the CAT costs abot 140/50 quid, but some people say it can be removed and cleaned with a STEAM cleaner (not jet wash),

The particle filter would clog up faster than it should as the soot particles would not be able to burn off.

Malcom: The particle filter is the second one fitted downstream of the cat.

hopefully this doesn't have any relevance to Xantia Hdi's?

You will get a notification on the same screen that the filter needs replacing as it becomes due.
Flow sensors upstream and downstream check the flow and let you know when to replace it.

It was possible to clean them, a very messy and time consuming procedure though. This is now technically forbidden as the crap washed out of them has to be properly disposed of and not allowed to flow into the nearest drain.

Part of the cost of fitting one will be the cost of disposal. Sometimes they offer reconditioned filters but these are said not to last anywhere near as long as the new ones. Average life is around 100,000 miles, allegedly.

The filters are around £145 and you should be able to swap one yourself without much bother.

May be available from after market sources (EuroCarParts, GSF, Bosal, etc.)
