Replacing Diesel Filter 2.0 Hdi Engine

[Kevin]

I have a 2000 Xantia 2.0 HDi Forte. I have no idea when the diesel filter was last changed. I have heard that this can be a tricky job and debris can damage the fuel pump if dislodged.

 

Anyone changed theirs? Is it a DIY job?

Providing you're reasonably competent, it's a straightforward job. I did my C5 just a couple of days ago. Fifteen minute job. Not all HDIs have the same filters fitted. Yours may be like this one:-

which is on my daughters Xsara. If so, spread out some old rags to catch spills and disconnect the two fuel pipes by pressing down the white inserts and disconnecting the connector. The release pulls upwards. The centre of top stays still and the outer ring twists off. Have an old ice cream container (or similar) to put the old filter in. Syphon out the fuel and clean the bowl bottom. Put in the new filter, use a new O ring and replace everything. Switch on and off the ignition a few times and use the hand primer to fill the bowl.

Thank you very much. The picture is very useful.

 

Just one last question. Where is the hand primer?

Follow the pipe going off to the left. When you reach the 'sausage shape', that's the primer bulb. Keep squeezing until it feels firm.

I was going to change the filter on my Xantia 2.0 HDi today but the Haynes manual put me off!

 

It says the filter housing must be cleaned with parafin or "injector test fluid" and then dried only with special "Resistel" cleaning cloth and not anything else. (I used to use kitchen roll to get any bits out of the filter housing on the 1.9TD).

It also says to renew the drain screw and it's "o" ring each time the filter is drained.

Do people really do all this? I couldn't find the Resistel cloths on eBay, so I'm thinking that means they are not in common use?!

 

Johndouglas' photo and description of how to release the hose connectors is useful - Thanks.

 

I also have an intermittent engine warning light and P0230 fault code. (Primary fuel system). It appears this may be the fuel tank pump or the non return valve in that pump, or a blocked fuel filter or an always open pressure relief/return (to tank) valve in the fuel filter canister assembly.

Can anyone point me towards which outlet on the filter housing has this pressure relief valve on it so that I can take a look at it when I change the filter?

 

Thanks

I managed to change my diesel filter, but it isn't an easy job. There is a special tool for Bosch HDi filter housings to unscrew the top. I used an oil filter wrench, but struggled a bit getting grip.

 

Yes Hayne's is a bit over the top regarding the cleanliness. Just be sensible. The most important thing after the filter is inserted into the housing, is to prime or top up the new filter with diesel fuel before you put the top back on.

 

Further prime the system by turning on the ignition once after attaching the pipe from the tank, which activates the fuel pump. Put a large rag under the filter to catch surplus fuel. Connect the other pipe to the engine and turn the ignition on again draining off a little fuel from the drain plug on the side which is for removing water build up normally.

 

Engine should start straight away after that.

I think you can disregard some of the baloney in Haynes. That's not to say you should not take every care to work cleanly. There are different fuel filters on HDI's. We have two and they are both different. Personally, I never open the drain taps since I change the filters every 10K. Begin by pushing some rags under the bowl to catch spillage. Carefully remove the pipe connections and keep them clean. Remove the top and lift out the filter into a container. I use an old ice-cream box. Then syphon out the contents using an oven baster. An occasional stir with the baster ensures that any water or crud comes out with the diesel. When the bowl is empty, fit the new filter, change the rubber ring and replace the top. Switch on and off a few times to operate the pump. Also use the hand primer.

No connection or other financial interest but just seen this on flea-bay Citroen fuel filter wrench

 

Suppose it is cheap enough and thinking of my 2.0HDI Berlingo, think my strap-type filter wrench may be a bit cumbersome.

 

But hold on...... with a bit of spare time, a hacksaw, drill and a file, oh yes and a suitable piece of 5 or 6mm steel plate, it doesn't look beyond the realms of possibility to make your own wrench. Having got workshop facilities at my disposal, I think this may be the route I take in preparedness for filter changing.

 

Just surfing further and it appears that Machine Mart also do one see link Machine Mart Filter Wrench
