How to replace fuel filter on a Peugeot 508 2.0 HDI RXH - 4WD diesel hybrid

First clean the aria around the filter housing before you start to dismantle!
Most dirt comes in through the housing and fill places.
And look into the filterhousing if you see some dirt inside or something else
I hope you enjoy.
