This happens when the car is at a set speed/load on a motorway it will inject the chemical and burn the carbon Effectively cleaning itself. This is a problem because if it's going through a regen cycle of around 10minutes if it's not complete the carbon isn't burned off till the next cycle and they often become blocked. And need to be manually cleaned or taken to a dealership for a forced regeneration. I believe PSA was the first to introduce it.
Its still a DPF though, just with the Eolys fluid to lower the combustion temp of the soot particles.
A lot of vehicles use the same system with the Eolys (Mondeos, Mk5 Golf and equivalent VAGs for example, as I've been looking at these lately lol) but they still call it a DPF.
FAP just stands for 'Filtre à particules'.
