2.2 HDI Particle Filter - machika
I dropped off the Xantia today for its annual service and MOT. The chap who owns the garage business told me that the particle filter on the C5 2.2 HDI requires replacing at 60,000 miles. Is this correct? Apparently they cost around £400.

I've heard of this. Theres a fluid that needs replacing isn't there?
Someone with more knowledge will be along in a bit
C5 2.2 HDI Particle Filter - machika
Yes there is some fluid that needs replacing but the level of it can't be checked. One has to rely on the car's computer to monitor it. Some weeks ago, a warning notice was displayed on the control panel to warn of a low level of this fluid. However, it only flashed up for a few seconds and has never shown up again since.

You need filter and fluid replacing. I hear its around a £500 job.
C5 2.2 HDI Particle Filter - machika
I am left wondering whether the control panel read out was an error or not. I could easily have missed it, as it was on for a very short time. The car has only done about 38,000 miles, so it seems a bit soon to need topping up to me. I have no idea how much it would cost to top it up at the moment.

By the way, I was referring to my post in the earlier thread on this subject.
C5 2.2 HDI Particle Filter - DSLRed
Does this particle filter only apply to the 2.2 HDI, which is only used on the automatic, or the 2.0 HDI as well.

Seems strange that 2 similar engines would have different requirements, but I believe that the 2.0 gets away with this one.
C5 2.2 HDI Particle Filter - machika
I am fairly certain that the new 2.0 HDI doesn't have a particle filter. I find it strange, also, that the 407 HDI auto has the two litre engine, whereas the new C5 continues with the 2.2 litre engine.

"only done about 38,000 miles"

C5 2.2 HDI Particle Filter - dieselnut
I was considering this model myself to replace my ageing XM 2.5 TD. The engine seemed more suited to the heavier C5 than the 110bhp 2 litre engine. But i'm completly put off by a heavy scheduled repair bill. Perhaps you can do away with this particle filter with a piece of straight through pipe, the same as you can do away with a cat on diesels.
Does anyone know or has anyone done this ???
C5 2.2 HDI Particle Filter - machika
I have just checked the maintenance schedule that came with the C5. Item 4 in the list of specific operations is:

C5 equipped with particle filter: Clean particle filter and check Eolys fluid level.

For normal use, this is scheduled to be done every 50,000 miles. There is no mention of a requirement to replace the filter.

I have been told that the level of the Eolys fluid can't be checked. How true this is, I don't know.

How can a manufacturer specify that the filter only needs cleaning periodically and then say it has to be replaced instead?
C5 2.2 HDI Particle Filter - Armitage Shanks {p}
My 1590cc Hdi Peugeot has a particle filter, something to do with making it Euro IV compliant. This has the added and disturbing effect that, from time to time, when I stop the engine and park the cooling fan runs on for up to 10 minutes. This is all something to do with the particle filter and the expensive fluid that gets topped up at about 70,000 miles. My dealer showed me a computer print out from Peugeot technical explaining this, as I thought it was a fault, but they wouldn't let me keep a copy of it.

Sorry for the delay in replying to your query; so far as I recall the only service action needed was to replenish the fluid that the system uses.

The 407 is completely new so has been engineered to suit the new Ford/PSA engine, the C5 is a facelift so it was probably more cost effective to continue with the 2.2 than to reengineer for the new 2.0.

what would be the consequences of just ignoring it? something go bang? increased emissions? decreased economy? is it something that could be lived with?

WTM
C5 2.2 HDI Particle Filter - machika
I am not saying it should be ignored, it is just that the manufacturer specified that the filter only needed cleaning. It is a major change to have to replace it at a cost of around £400 and why should the owners of these cars have to foot the bill for a mistake that the manufacturer has made?

When did Citroen decide that it needed replacing and what have they done about notifying the owners of these cars?

C5 2.2 HDI Particle Filter - Mondaywoe
Only the 2.2 has the particle filter (my one unfortunately!) As far as I know the 'replacement' filter you get is actually a recycled one and at the moment there is nowhere in the UK that can recycle them so they're shipped back to France for a powerwash (says he cynically!) and returned at great cost to us. The last time I asked my dealer about it he said the price is coming down and off the top of his head he thought he could now do one for around £275 (part only) The EOLYS fluid is refilled at the same time (pricey stuff too)

Having said all that the filter does a marvellous job. My C5 is just coming up to 45,000 and the tailpipe interior is still spotless shiny metal - as new! I can't honestly say I have ever seen anything coming out since I bought the car!

One compensation might be that the exhaust system beyond the filter should last much longer, so in the long term cost of ownership might not be that greater.

The latest C5s have 100,000 intervals for filter changes - older ones like mine are 50,000.

Will let you know what it sets me back very soon - I'm on 45,000 so won't be long!

Graeme
C5 2.2 HDI Particle Filter - machika
Seems like you have accepted the situation. Are you not annoyed that the service schedule says that the filter only needs cleaning, not replacing?

If the owners of these cars protested collectively, it might produce a helpful response from Citroen.

I doubt very much that one section of exhaust would be anywhere near the cost of replacing the filter every 50,000 miles.

Does anyone know what has been done to extend the interval from 50,000 to 100,000 miles?
C5 2.2 HDI Particle Filter - colinh
Somebody's working on it:

"Castrol, strategic partner of BMW, have developed a new lubricant with `Clean Performance TechnologyTM` in close cooperation with BMW, which sets new standards in the industry. Castrol SLX LL04 0W-30 is specially engineered to keep the engine and exhaust system clean, reducing harmful emissions to the environment. SLX LL04 is developed for the new generation of BMW cars with particulate filters and meets the latest specifications BMW Longlife04. Due to its `Clean Performance TechnologyTM`, SLX LL04 reduces long term blocking of the particle filters and can be used in all BMW diesel and petrol engines (excluding M series). Castrol is the first lubricant manufacturer to bring a `Clean Performance TechnologyTM` oil onto the market."

I'm puzzled why you are complaining about this filter. Weren't you aware of it when you bought the car? It is not a 'fault' as such, it is part of the design philisophy of the car and I believe part of Citroen's marketing emphasises the low emissions obtained by using this technology.

I am complaining because the maintenance schedule says the filter only needs cleaning every 50k miles. Now Citroen are saying that it needs replacing, which is quite a difference I would say. So no, I didn't know that it needed replacing when I bought it.

As for using this technology, the new 2.0 HDI engine doesn't have a particle filter and yet Citroen are oontinuing to fit the 2.2 HDI to the diesel auto model, whereas Peugeot are using the 2.0 HDI.

Do you happen to know the maintenance requirements for the particle filter in the Focus?

Why would it be necessary to re-engineer the C5 to mate up the new 2.0 HDI with an auto box? The previouse C5 used to have the old 2.0 HDI mated to the auto transmission.

I have an internal Ford doc on the new Focus (given by a friendly chap at my local dealership), I will look later and see what detail it gives in this regard.

I guess that C5 manuals sell in high enough quantities to justify re-engineering the car to fit the new 2.0HDi however the autos sell in much smaller volumes hence it being, perhaps, uneconomical to re-engineer a new subframe etc etc to fit the new 2.0/auto combination. Much easier to continue with the older 2.2 auto. Presumably the new 2.0 and auto box, as per the 407, will be fitted to the C5 replacement which must be due in approx 2 years.

The whole idea of the particle filter is to eliminate black smoke and has a clever way of regenerating its effectiveness by a self cleaning action using the special fluid.

C5 2.2 HDI Particle Filter - machika
It is interesting to see, also, that Peugeot are offering non FAP and FAP alternatives for their 407 HDI range.
C5 2.2 HDI Particle Filter - cheddar
The internal Ford doc on the new Focus given by a friendly chap at my local dealership that I referred to above quotes:

"On the 1.6 and 2.0 litre diesel engines the fuel additive tank must be refilled every 37500 miles and the diesel particle filter renewed every 75000 miles ..."

It also says elsewhere "both diesel engines will be available with a Diesel Particulate Filter" which seems to imply that the particle filter is an option however I am not sure about this.
C5 2.2 HDI Particle Filter - cheddar
Sorry, I did not quote the whole piece, yes it refers to the EU4 engines.

However I did not know that the EU3 1.6 was being fitted in the Focus, I thought it was only the C-Max and was now being replaced by the EU4.

The 92ps engine is the one in the Zetec S Fiesta, perhaps it's lack of need for a particle filter is one reason Ford fitted it to the Fiesta instead of the 110.


Regards.
C5 2.2 HDI Particle Filter - machika
It will be interesting to see how much Ford charge for a new filter. It looks replacement of the filter is now the only option and that simply cleaning it is not an option.
C5 2.2 HDI Particle Filter - machika
Got an estimate today from the local Citroen main dealer for topping up the fuel additive tank. The labour alone would be £80+Vat. The cost of the additive would depend on the amount required to top it up (can't understand this as, if it is at the minimum level, it should be a standard amount), so I don't have any idea of the cost of the additive.

I was also told there could be a faulty sensor in the additive tank which would require a new tank. Wonderful, isn't it?
C5 2.2 HDI Particle Filter - machika
I checked with a local independent garage today (recommended by this web site) and they don't deal with the business of replenishing the additive. So, unless I can find someone else to do it, it looks like the main dealer is the only one I can use. They even charge around £28 just to check the level.
C5 2.2 HDI Particle Filter - machika
On reflection, it seems that the service interval for checking and replenishing the fuel additive is largely guess work. As this is a fuel additive, the rate at which it is used must be governed by fuel consumption which can vary trememdously from car to another. An automatic, like ours, will obviously use more fuel than a car with a manual gearbox.

This would explain why we have had the message on the control panel at around 38K miles, rather than at around 50K miles. The chap at the independent garage did tell me that he has known it to vary from 40K miles right up to 70K miles.
C5 2.2 HDI Particle Filter - machika
Well, I eventually took the car to the local main dealer, as the chap who services our Citroens has still to get the required computer equipment.

Total cost of topping up fuel additive (6 litres) approx £158.
C5 2.2 HDI Particle Filter - andyconda
£160 for fuel additive... £500 to replace the particle filter... makes me think that it's only economic to run a diesel if you do high mileages!

C5 2.2 HDI Particle Filter - Rishab C
I'm sure there will soon be websites telling you how to do away with these silly contraptions, which I'm sure are only to help sell more new cars to companies by making them obsolete quicker.
C5 2.2 HDI Particle Filter - machika
They actually gave me a 10% discount too. They must have felt sorry for me! It amazes me that it takes over an hour to do the job. Then you have to pay for two quantities of the fluid, a 5 litre pack and a 1 litre pack. The 1 litre pack costs a third of the 5 litre pack, which really annoys me.

I think I made a comment in an earlier post that these cars will not be wanted by anyone when they get to be worth very little, as the cost of maintaining them will be prohibitive. One piece of good news that I did get, was that a reconditioned particle filter costs about £150, rather than the £400 that they charge for a new one. I can't see many people opting to have a new one. Mind you, I don't know how much it will cost for the labour to fit it.
C5 2.2 HDI Particle Filter - Timaru
I've only done 16,000 miles in my '03 so hopefully it'll be quite a while before I need a top up. When the dreaded day dawns I'll combine the work with a "booze cruise" I bet it's 60% cheaper in France.

C5 2.2 HDI Particle Filter - nortones2
Thats an expensive item, then. Nothing I could find to indicate how to refill and to source a cheaper Cerium (I take it this is the additive) source, and the Citroen Owners club didn't seem to give out much without joining!
C5 2.2 HDI Particle Filter - machika
I don't know what the additive is called. I contacted a local independent, who used to specialise in Citroens, but they don't deal with this item. I don't know if they can't do it, or don't want to do it, but the person I spoke to said that it was extremely toxic stuff. It seems like an odd approach if they don't want to do it, as there will be a raft of cars out there before long, which need to have this stuff replenished.

I think I have asked this question before but don't believe it was ever answered.

Does the MoT have the ability to check Euro 4 compliance anyway? Is it still just a smoke test?

If not testable, why bother with topping up the fluid? or does it start giving stop engine warnings if the fluid is low?

I'm no expert on these things (and don't intend ever to be) but I would think that if you don't replenish the fluid then the filter would eventually plug up with soot.

C5 2.2 HDI Particle Filter - machika
I don't know of anywhere where this is available. The usual practice is to buy an exchange unit, which cost me around £160, I think. Still cheaper to replenish the EOLYS fluid than keep replacing the filter. I don't know if the engine can be run without the filter. Anyone know?
C5 2.2 HDI Particle Filter - dieselnut
The Citroen web site tells you the filter can be jet washed clean.
I have done this job myself with excellent results, better fuel economy & no more anti-polution fault messages. But some say the washed out particles could be a health hazard.
I think probably no more hazard than the soot particles that would have otherwise gone into the atmosphere.
You can't run without this filter, the ECU monitors exhaust pressure & temperature to decide when to regenerate the filter. So it would keep going through its routine of injecting (wasting) extra fuel to heat the exhaust which this system does anyway & probably revert to 'limp home mode' when it didn't get the changes in sensor readings it expected.
If you could find someone who was knowledgable about the software they may be able to disable the function in the ECU. I understand some cars wern't fitted with the filter when they ran out of EOLYS at some period, so must have had a different ECU fitted or modified software.
C5 2.2 HDI Particle Filter - Armitage Shanks {p}
At some point in 2004 a number of Peugeots were sold without particle filters as there was no EOLYS to put in the system. Thus the technology must exist somewhere, to run PSA EURO 4 engines without the filter and the nasty liquid.

HI all, just bought a 2.2 HDI (at auction) and almost immediately got the warning.
Lots of online research worried me....
But, I have now refilled the fluid (expensive stuff £120 odd), but not a hard job, 45 mins I guess.
Then I took off the exhaust filter and cleaned that.......
IMPORTANT Tip. Find someone who has a good sized pottery kiln. makes cleaning the filter simple. I was lucky that it fitted my kiln as a complete unit. I guess the filter can come out of its housing to go in a smaller kiln.
I cooked mine at 660 Deg C for over an hour, so overall it took 6 hours (heating and cooling). Came up nice and clean, then I hoovered out any remaining ash from the cells.
Actual car work time about an hour.
So, at home, in a car port, no pit, I have refilled the fluid and cleaned the Exhaust filter for a cost of £120 and around 2 hours work (plus I guess £5 electricity for the kiln) still have to get the message on the display reset, but it doesn't worry me now!

This thread about eolys fluid and exhaust filters has reinforced my feeling that modern diesels aren't that economical to run in the long term. What with the extra cost of buying the engine in the first place, and possible problems with dual mass flywheels and something else I can't quite remember now, it could be that petrol engines are the way to go for economy.

All things being relative, of course.
