I have just done my first DPF fluid (Eolys) reservoir top-up today, and it was a fairly straightforward job, but I thought I would write this to help others on here, who may be thinking of having a go.
I own a 2015 B9 1.6 HDi L2 van, and the low DPF warning started displaying on the centre console at 115,850 miles. The message simply said “Engine fault”, “Risk of filter clogging” i.e. the Particulate Filter.
I already had the fluid top-up kit, which I had bought when my van had only done 75,000 miles. The Kit cost £130 from a Citroen dealer, and includes 3L of the fluid, but I found out today that my Eolys tank only holds 2L. This liquid is supposed to be pretty toxic stuff, so always wear gloves and eye protection while working with it.
I reversed my van up on to car ramps and simultaneously raised the front wheels onto thick planks of wood as I went backwards. This gave me more than enough space to crawl under the van, and access the reservoir, which is just in front of the offside rear wheel (Drivers side). It is hidden behind a plastic cover held on with 3 x 10mm bolts. As ever, it’s a good idea to disconnect the vehicle battery at this point.
You have to remove the whole plastic Eolys fluid tank to top it up (it’s easier anyway), It is simply held in position by one 13mm nut on a long captive bolt on one corner (you may need a 13mm box spanner to access it), and 2 re-useable white plastic rivets which attach the tank to the exhaust pipe heat shield. You then have to move the tank diagonally from the left rear towards the front right to disengage lugs on the top of the tank which locate on 2 large fixed “buttons” on the underside of the van. This enables you to drop the Eolys tank down enough to disengage an electrical connection and the fluid pump outlet pipe.
With the tank out and placed upright and level, disconnect the “U” shaped flexible pipe on top of the tank and connect the pipe stub of the new fluid filler bottle connector to this flexible pipe. Then connect an “overflow” pipe to the plastic pipe stub on the tank which the U shaped pipe had formerly been connected to, and feed this overflow pipe into an empty plastic bottle, to catch any surplus from the filling operation.
Proceed to fill the tank with new fluid until it starts to come out of the overflow. This will be after you have put in about 2L in.
Re-assembly is simply the reverse of the above. You will have to have the DPF fluid counter reset in the ECU to cancel the dashboard error messages. You can either pay a Citroen dealer £60 to do this, or find someone on here with the requisite laptop and software, who will do it for a lot less!
