Elloys additive is not what we call it here in Aust it is sold as Add Blue. So that is why I did not understand what you were on about, anyway the tank form what I can see is located under the car and is difficult to access unless you have a hoist, the fluid is dangerous to handle and you will not be able to do the re set in the ecu with out Peugeot software, there is a set interval for re filling the tank, so I would recommend that this is done by a dealer.
