Sounds an easy fix john, just a new fuel filter. If its bad enough to turn on a warning you should feel a boost from the car when the jobs done. Put it down to maintenance.

Thats also the warning for a blocked DPF

[johnboy231]

yeh thought as much just got it to do a regeneration but need to get diagnostics on it

[sterion75]

I live and learn

[johnboy231]

update had it on diagnostics this morning and heres the list

iat sensor
part filter blocked
additvice empty
additive system faulty
air mass low flow

im guessing the reason system is faulty is cos of no eoly fluid and being inactive well i got a 4 day weekend next week so ill be doing it all then and have it reset. at same time im gonna do a full service and fit a cambelt.
thankfully after 2 weeks of ownership i can do this stuff my self so labour is free.

has anyone got any good recepies of cleaners to put down part filter before a hot jet wash

Just water is fine , but make sure you dry it , if Mrs is out stick it in the oven

Is it a 1.4, 1.6 or 2.0 HDi?

If it's a 1.6l I have photos and a description of how to remove the DPF and clean it out (did it my self this morning) it will take about 3 hours total for removal, clean out, check, install and clearing of fault codes.

Get the photo`s up

This is the process for the 1.6 HDi version, the 2.0l version is much easier

I'm useless with photo shop so if someone can message me with an email address that can re-size the pictures I’ll gladly mail them.

The steps to removing the filter are as follows.

(1) Ensure the engine is warm, not hot it makes it easier to remove the filter.

(2) Disconnect the DPF sensor pipe from the filter going to the differential sensor at the sensor itself. If in doubt it is the lower of the 2 pipes.

(3) Open the clamp holding the 2 DPF sensor pipes located 1/2 way down the front of the heat shield facing the radiator. Place a piece of card board to prevent damaging your radiator while unbolting the clamp. When the clamp is open far enough slip the lower of the 2 pipes out.

(4) Remove the 3 bolts holding the small section of heat shield over the turbo. It will become clear later what the reason for this is.

(5) Raise the car up on a lift and remove the plastic under protection plate covering the engine.

(6) At the bottom of the DPF remove the last 2 bolts holding the bottom of the heat shield in-place.

(7) Release the DPF from the flexible section of the exhaust, DO NOT be rough with this flexible coupling as it is easy to damage. This can be a bit difficult and the clamp could be badly oxidized so buying a spare clamp in advance might be an idea.

(8) On the bottom of the DPF behind the heat shield there is a large clamp that needs to be opened. To access it place something between the DPF and heat shield (I used the handle of a hammer) to push the heat shield in the direction of the radiator.

(9) Undo the clamp and then use a screw driver to spread the sectioned edge under the clamp that holds the DPF in place.

(10) When the DPF is loosened sufficiently (it should have a little bit of play left and right) remove what ever you had placed between the DPF and the heat shield.

(11) Pull the DPF straight down, it will resist a little but should come out all the same.

(12) Place the DPF in a large bucket filter facing down on 2 sticks. Using a high pressure washer force water through the exhaust outlet section of the filter housing, this will start the first stage of freeing up all the crud in the filter.The filter will need a good soak to start the process

(13) After about 30 mins remove the filter from the bucket. Using an industrial plastic bag (the type used for rubble collection) and a tie-wrap block the exhaust side of the filter housing and then fold the piece of of the DPF sensor rubber tubing in two to prevent water flowing out through it.

(14) Using the power washer blast water through the filter side of the DPF, not the exhaust side. This process will take about 30 mins. The reason for washing the filter in reverse is that having blocked the exhaust side all the water you pump in will be forced out through the filter reverse washing it.

NOTE: Wear a face shield when washing the filter out as the crud will splash in every direction.

The crud coming out will be red in colour and there will be plenty of it, as soon as you think a section is clear even more crud will start oozing out (you could spend the entire day trying to clean it) so 30 mins of continuous water pressure moving the head of the high pressure water sprayer in a circular motion should suffice.

(15) Re-assembly is the reverse of dis-assembly; ensure you let the DPF stand for about 15 mins to drain all water.
