Best to pop your VIN up so we can identify the engine type and system (please post your VIN in full without spaces - it will be automatically masked from public view after submitting your post & will only be visible to staff).

Re: Eolys tank location Citroen Relay 2017
The Eolys tank for the DPF additive (not to be confused with the Adblue Tank for the SCR System which may also be fitted and is a separate system) should be located next to the fuel tank, normally on the fuel filler side. It will be concealed by a case and likely some heat protective shielding which has to be removed for access.
There should be a warning and or message when the additive level needs topping up.

Re: Eolys tank location Citroen Relay 2017
do you know the correct type and quantity of Eolys fluid for these engines? I have the same, on a Boxer, which is on 85k miles, wanting to refill it before it damages itself by running low
thanks martin A

If it's for your vehicle, VIN ending 692, then you need Powerflex Additive for your build date which is 14675.

Re: Eolys tank location Citroen Relay 2017
thanks for the info concerning the Eolys type for future use with this 2017 BlueHdi. Much appreciated
have now found out that its tank is in the vicinity of the passenger foot well, and that from on old Diagbox, exhaust line information report, that the tank holds 2.6l with mine around half full on 86k miles. So in no hurry to fill it at this time of year.
seems like this system, despite its added complexity, does a good job of keeping the DPF clear, compared with the systems used by other manufactures who rely on added diesel during the more frequent regenerations whilst this engine is averaging 750 miles between its last 10 regenerations.
