hi all just had a look under the car and found the eolys tank.
has two tubes at the back.
could perhaps fill through these.

it gets filled with a tube going into the top of the tank, the Eolys fluid comes with a kit for filling it containing everything you need.Are you sure its DPX 42 you need (up to RP no 9492) as i think this comes in 5 litre containers,its the Eolys 176 that comes in 3 litre kits & the two fluids cant be mixed.
The filters arent cleaned at the dealers,exchange filters are fitted.the chances are you will need the FAP ECU reset as it works out how much fluid has been used theoretically.
the thing about making the car rev for ages at fast idle is a forced regeneration of the filter,this only needs to get done in extreme cases,give the car a good thrashing regularly & you wont need this done.

hi guys, thanks for all your comments.
i read on one forum that the dealer can run a forced regeneration, that is run the engine at high revs to produce enough heat to burn off the soot.
as i tow a lot i am told that the filter regenates every 300 to 350 miles, so it would seem that the filter might not need cleaning until the sensors pick up a blockage.
as to taking filter out, would the sensor not pick up the difference in pressure?
i am sure it would run much better without a filter.
how about fitting a straight thru exhaust?
my 2.2 goes like stink since i fitted a k&n air filter, and gives 26.5 towing and up to 46 touring. ave 38.5.
i like the exclusive as it has a sport setting for the suspension, makes it firm for towing.
i have looked at the new models of c5 and they are all fitted with a particle filter, cause of euro 2008 emissions regs, so if you stay with pug/cits they will all need sevicing.
more money for dealers eh!!!

hi all
thanks for the replies.
does anyone have a diagram of how to fill eolys tank.
thanks wheeler. how do you get into the tank.
is it through the top of the fuel tank?

The rorced & natural re-gen burns off soot in the filter but the problem is the Eolys fluid doesent burn & remains trapped in the filter,hence the reason the filter needs changed.
Yes the pressure sensor would pick up a missing filter & bring up a warning message on the dash.

(Sorry to butt in but I have been considering how to run sans filter too) Would a minimum pressure differential alarm be produced too? There has to be some way of modifying , surely?

It would be the enging management light /anti pollution warning that would come on.
In theory i cant see why it wouldnt be possible to hollow out or remove the filter & fit a bypass pipe bypass pipe then get the FAP system un programmed with a Lexia or Proxia machine.

Maybe an answer to some of your questions??

This subject has been discussed so many times both on this forum and others it's becoming boring

.

From my recollection in summary of a variety of sources Wheelers solution will work. You can tell the engine ECU using a Lexia that a FAP system isn't fitted then having removed the FAP filter the EOLYS injection system is disabled by disconnecting pump and ECU connections.

The engine ECU no longer looks at the diff pressure sensor because it doesn't need to run a regeneration cycle.
However you will need to clean the soot of the back of your car on a more regular basis.

Alternatively you can remove the filter stuff some wire mesh in the cavity to give a nominal pressure diff and keep topping up the EOLYS tank with diesel.

As regards cleaning the FAP my understanding is that yes. it can be cleaned to a limited extent using a high pressure cleaner, however the water that comes out is toxic and should not be disposed off in normal drains, alias, should be disposed of in an environmentaly acceptable manner. This will not clean the filter 100% though, it will remove all loose ash, however cerine stuck in the filter is a different matter this requires a chemical bath which is what I believe happens with filters returned through PSA others? well who knows.

Finally bitch as we may about FAPs and the cost of maintenance they do make diesel exhaust much more pleasant, they are a legal requirement in many countries and fitted as standard on pretty well all new diesel models they are here to stay get used to it.

I too have wondered this, the 2.2 is often said to be the worse engine between it and the 2.0 110. Maybe its like catalitic convertors, they always used to sap a cars power.

I think that the 2.2 gets a bad press largely because there seem to be lots of reports of unresolved Anti Pollution warnings and fuel consumption. IMHO the former happens because many who maintain these cars don't understand them and don't have the equipment to do the job properly, I am also of the opinion that the modulated turbo and it's default no vacuum state exacerbates this. As regards fuel consumption well it does have an extra 28 Bhp over the early 2.0 Ltr and it is lively 40 -45 is achievable on a long motorway run however high twenties low thirties is more common around town. In my view if all your mileage is long distance Mway then it's a good car, however if the majority of your distance is 15 -25 mile sectors with lots of urban work then it isn't so good.

Having said all that you have had a 2.2 and now a 1.6 how do you find the 1.6 after the 2.2 I ask because I am thinking of going the same route the price of diesel will only go one way from now and that at an ever accelerating rate.

My 2.2 (Twin Turbo 173) does average 46, motorways 50ish and low 40's round town.

I believe the 2.0 does the same. When I drove the 1.6 I found it underpowered and I guess the economy gain will be minimal because the engine will have to be driven harder.

Am I simple or is this all a load of tosh regarding emissions?

As I see it, if this container becomes absolutely full of soot particulates then it only represents a litre or two in volume (or whatever the volume of the tank is).

Eco-wise we've gone too far and I think, with my cynics hat on, that much of the complexities on modern cars are there for profit through servicing.
