You just need to replace the filter number 6 in the image 2 posts above.
I replaced my fuel filter on my 1.6HDi 75HP 2013 a few weeks ago with this one PURFLUX CS762 http://www.mister-auto.be/fl/brandstoffi...80_g9.html
In these newer 8V motors, (DV6C, D, etc) , changing air and fuel filter is a bit simpler and made easy. Air filter is just 3 torx screws, one clamp and it is out...the diesel filter is also easy, it comes out by removing the 3 fuel pipes, one electric plug and 2x8mm screws. The filter itself is the metal part under the plastic lid you see on the image behind the oil filler cap. When it is changed, the metal part will look clear and new, not oxidised.
Changing that fuel filter is so easy compared to the older one. So much access and very quick.
Here's a nice youtube video as well.
