C5 (X7) 2008 2.0 Hdi Particulate Fluid Level Warning

[Higgo]

Please be gentle on me - first Citroen, first diesel with DPF renegeration, first post here...

 

I've recently bought a 2008 C5 2.0 HDi (newer shape) and at my last fill up I got the message that the 'Particulate Fluid Level is too low'. I don't propose to do it myself as I don't have the tools, space (street parking), time or skills but I want to know what needs doing so I can ask the local garage I use. 

 

I've had conflicting information from the internet about which fluid it is. Also when I contacted my nearest Citroen dealer reg number they called me back saying that it was a pouch of fluid that needed swapping - I thought the pouch system was only on newer cars so I'm not sure I completely trust them. 

 

So... is there any way (from VIN etc) I can tell before they start the job whether it is a tank that needs filling or a pouch that needs swapping? And if it's a tank, what fluid?

Welcome to the forum.

 

Your car will have an additive tank and not a pouch. To check which additive used, the tank filling pipe has a coloured part on the connection - green is for eolys 176 or Infineum F7995, blue for eolys powerflex and white or no colour is eolys DPX 42. If you have eolys 176 you can use 176 (but it may not be available any more) or infineum F7995. If you have infineum you should use infineum. Powerflex can not mix with the others.

 

As well as colour on the filling pipe you need to use the car RPO number which is on the sticker with the tyre pressures on a door pillar (as well as in the book with the service stamps on the inside cover). The rpo number is a code for the manufacturing date.

- Vehicles up to rpo 9492 should have DPX 42,

- rpo 9492 to 12110 or 12166 should be eolys 176

- but for the C5 (X7) from rpo 12125 it should be infineum F7995.

 

To fill the additive tank it is a case of connecting the refill bottle to the filling pipe on the tank with a hose that screws on the bottle and letting it run in. A full tank holds about 3 litres which ought to do about 80k miles. However, the fluid level is done by a calculation on the number of diesel tank fills so the car will need a diagnostic to tell it the fluid has been topped up - you will need to use a garage that has the correct diagnostic tool to do this so you may end up using a Citroen dealer. If you do not do the diagnostic the low level message will not go, but the fluid will still be dosed to the fuel tank so the dpf should not block up.

Thanks for this - very helpful.

I'll check the RPO.

Where is the tank filling pipe? Is it easy to get to?

[Higgo]

My RPO is 11421CJ so built 15th Feb '08 (in Rennes) and therefore Eolys 176 (but infinium F7995 is also suitable).

The tank filling pipe is on the tank itself. There is a u-tube video here which shows how to do it https://www.youtube.com/watch?v=IyEpmE5MfWs
