DV6C Diesel Filter Change (8 valve 1.6HDi in Picassos, C4s, DS4s)

Here's a few tips on the filter change.

1st photo shows location (up under scuttle on right hand side).

2nd photo shows two off filter retaining screws, 8mm hex heads. Disconnect the electrical connector first. I used a deep offset spanner to access the screw heads. These are captive screws, you should not need to remove them completely.

3rd photo shows the fuel hoses to be removed: centre white and the green connector.

Then disconnect the clip supporting the fuel hose, ease the filter up and forwards to improve access to the left hand fuel connector. (4th photo).

The actual filter cover lifts away complete with the aluminium bodies filter.
Take it away to a clean area. Lift the central electrical connector and twist gently, the open the lower drain (water) valve. Remove the filter cover by undoing the three off T15 torx headed screws. Install new filter (check new upper seal is in place) Remove the lower protective cap that comes with the new filter.

Reinstall the filter, screw down with the two 8mm hex screws, connect electrical connector, make sure water drain valve is closed (this is the central electrical connector). Connect all three fuel hoses.

Now to prime the filter (last photo). Disconnect central fuel hose (white connector). Suck fuel through from tank (I used a Pela suction pump). Then prime the injection pump by pushing down the plunger.

Observe Cleanliness throughout!!!
