Adblue and Eolys.

There has been much discussion on the internet in general about whether cars fitted with an Adblue system are fitted with an Eolys tank. My understanding was that the Eolys system regenerated the DPF, and the Adblue reduced the nitrogen oxides to attain Euro 6 standards. Many people seem to think that Adblue would replace Eolys, including several motoring journals. I have never been able to find any confirmation one way or the other.

So, today I was at a Citroen agent, and bumped into the parts manager and the 'top' technician. They both confirm that cars with Adblue do indeed also have the Eolys system!
