Fap Filter Change And Elosys Refill - C5 2.2 Hdi

[trubmij]

In France problems with 2002 C5 SX 2.2 HDI and local Citroen Garage has diagnosed I need a new FAP filter and ELOSYS refill. Price around €500 ie £400. How much would it be if I left it to return to UK?

 

I have seen the computer diagnostics myself and that's what it says on the screen - seems dear but maybe cheaper than UK!

Sounds cheaper than the UK to me.....Parts are probably about the same price but i think you will find their labour rate is cheaper.

 

Had an invoice shown to me from france recently and it worked out there labour rate was about £56 per hour before tax........uk rates average around £75 per hour +vat

I agree with kfk. That price sounds pretty good, I would just get it done.

£450 2 years ago in UK for a new filter, fluid and ECU on my 2001 2.2HDi at 75,000 miles, so may not be much difference.

ive heard some crazy stuff on this ELOY stuff and expensive ( red X ) type stuff to clean the system but injects itself to the amount of fuel you have in the tank ive heard of people filling that tank with fuel diesel/petrol what ever your car runs on, perhaps others have had these ideas and tried them out? it could be a cash saver :)

Couldn't possibly work - and wouldn't save you any cash.

[techbod]

now tell me why you think that? all it is - is a computer programmed to pump fluid at certain times by mileage count ( do I put red X in when it says so on the bottle ).

 

im not saying don't do it but open to discussion as that's what it seems to be doing and probably a cash rip off as we are all aware off ( my book doesn't say use red X but its recommended only ) so don't discount it that quick :)

As I understand it the particulate filtration system needs the eloys fluid to work properly. Replacing the eloys with something else will surely cause premature clogging of the particulate filter?

[kfk]

and before we go anywhere on this one, dont go putting reddex or similar additives into the eolys tank, i'm not sure what the point is that Techbod is making here........maybe you would like to expand a bit?

Normal exhaust gas temperature is around 150C. Periodically, when the soot particles are trapped in the particle filter they need a temperature of 550C to burn them off. The eolys fluid which is a cerine-based substance has the ability to lower the burning temperature of the particles to 450C. The regeneration occurs every 300 miles or so. It’s the ash from the burning of the cerine which eventually blocks the filter and needs to be cleaned with high pressure jets. Now how can an extra squirt of diesel or redex put into 60 litres of diesel – or horse urine or pig’s pi$$ (as has been mentioned on other forums) achieve the required result.

You know, I'm pretty sure that if that Eolys fluid were not needed, then Citroen would not go to all the trouble of building the system into the FAP equipped cars. :)

[techbod]

let me explain a little better, eloy is an additive same as red X but not the same stuff so don't use it in place of eloy ( I didn't mean use it instead ) I was just pointing out what it is :lol: hopefully that clears that little bit up.

 

what my thoughts are is filling the eloys tank with normal petrol/diesel "depending on what the engine runs on of course" because its a programmed system that injects the additive into the fuel to help keep the fuel system cleaner hence the FAP filter so looking at the system it doesn't know what its injecting so it might as well be normal fuel,

 

Ive been on a few sites where they put normal fuel in without any problems including some who ave done a decat or should I say deFAPCAT and used higher octane fuel for more power ( remember fuel has a cleaner mixed n as standard ) and the FAP/CAT/EGR are just extras to keep the o2 cleaner and they cost lots and they can all be bypassed ( im not saying you should do this by any means ) but its worth considering if your into performance,

 

you can still use an additive in the tank like other do to increase performance and keep the fuel system clean so your looking after the environment which is the main thing cough :rolleyes:

edit* found this very ineresting

also found this and now wonder if the system even works well..

Look at this site

Its the official citroen site describing the fap system.

 

I found adding the eolys fluid a doddle, though a bit expensive. I reckon its best adding the stuff 1 litre at a time during the 10k service (early models) to spread the cost. Not yet had to do the particle filter so I don't know how difficult it is. The eolys fluid allows the system to burn off the carbon particles. Allowing the fluid to run out will eventually cause the particulate filter to clog up, ultimately fail sooner and could cost you in extra fuel and lost performance as it slowly chokes the exhaust system.
