C5 Eloyes fluid

Can anyone tell me what exactly triggers the injection of eloyes fluid into the fuel tank. Also is the amount of fluid injected proportionate to the number of litres of diesel which is put in? Anyone with some answers?

have a look at:

May be of help!

"The Eolys is stored in a tank adjacent to the main fuel tank and injected in proportion to the volume of fuel added during refuelling. For example, when filling up with 60 litres of fuel, the system will inject 37.5 ml of solution containing 1.9 g of cerine. The Eolys tank has a capacity of 5 litres, sufficient for 80,000 km."

Thank you for that pointer - it's very useful.

theres a little magnetic sensor on the fuel cap so that it knows when its been removed, the sensors can fail & cause problems with over injecting & using up all the fluid too early.

I've heard about this magnetic sensor in the fuel cap - which really takes me back to my original question. What does the triggering, the fuel gauge or the tank cap?

When the cap is removed the additive ecu 'gets ready' to inject additive,it takes note of how much fuel is there when the cap is removed & the amount injected is proportional to the amount of fuel added. i think a minimum of 10 litres must be added for it to inject.

Why are you wanting to know this anyway ? do you have a problem with yours ?

No problems! Just natural curiosity. Like to know the 'hows & whys'
