This forum has a download for the factory or Citroen franchised method for changing the diesel fuel filter. It needs Citroen special tools which includes a tee'd hose with proprietary connections for bleeding the new filter of air in-situ.

An alternative method. Follow the downloaded factory guide as far as swopping the heater housing over to the new filter housing. Then fill the housing with clean diesel, on the bench before installation back onto the car. Final bleeding can then be done by opening the normal water drain valve, and allowing this to syphon fuel through the filter.

Proof of this method, was the engine starting after the change on the first spin of the starter, The Citroen guide advises that pumping with the priming pump for two minutes is required, then further bleeding pumping whilst spinning on the starter (two people required).

To make easier the bench filling of the filter housing, some 10mm ID hose is required, plus clean diesel. If a small funnel is used on the end of the hose, it will be easier to get the diesel into the hose without spillage. Use a hose about 1 m long and have the funnel on the bench and the filter on the workshop floor. The meter head will force the diesel through the filter element. Fill via the entry port into the heater element so that the fuel is being filtered as it is being filled.

Note also that removal of the battery gives a lot more space to perform this operation. I got the replacement Delphi filter housing (same brand as Citroen had fitted) from Auto Equip Pieces (AES on the web). Their part number CIT168B, Delphi part number HDF939. Citroen ref 190195

Thanks Gordon. I'll see if I can add a page to the official Citroen guide with your info in the morning.

Don't suppose you have any pictures?

Dave, sorry no photos. Had my gloves on and covered in diesel so camera not a good idea. Actually the drgs in the download aren't too bad. Up to the point where thay show the diesel fuel lines from the rear, bulkhead side of the engine (a bit hard to follow!!).

If anyone needs the 10mm ID hose and a small funnel, there's plenty of that stuff on ebay for just a fe pounds

No problem, I have updated both fuel filter change .pdf's by adding a forward page attributed to you so it's a permanent record.

Hi Cardiff guy, hopefully didn't put you of with my post re changing the diesel fuel filter for the 1.6HDi. No special tools required other than the 10mm ID rubber hose and a small funnel to push into the end of the hose. I purchased these from ebay for about £6.00.

My main motivation for performing this kind of service is because I know I can, I know its properly carried out and while I'm at it, can check other items close at hand. It's a 5 year old car, bought new so I would hope to get a few more years of reliable service out of. Also my local dealer's setup is a major turn-off. A big bay with about 30 mechanics, multi-marque and lots of front desk staff getting between you and the guys doing the work. My other option is a long round trip drive.

Anyway, if you need more help to tackle these kind of jobs, just post. There's lots of people here that will help. Very good site and moderators that go out of their way to help. Great guys!

Thanks Gmerry, did mine yesterday and followed your method - like you it started first time. A couple of points to make following my experience.

1/ I needed to remove the battery, the windscreen wiper arms and the full width trim that attaches to the bottom of the windscreen so that I could access the filter pipe connections.

2/ It would make sense to do the air filter and the fuel filter at the same time as both require this level of "strip down"

3/ There are two electrical plugs (as well as the two diesel pipes) that need to be removed before the old filter is unclipped and lifted out. One is for the filter unit heater element which must be swapped onto the new filter and the other one seemed to peform no function at all as both the old and new filter units did not have any electrical connections inside the plastic socket!

I think some cars may have a "water in diesel filter" alarm system (hence the small plastic bleed down screw on top of the filter body) so either my car does not or there is a sensor that reqires no electrical contacts??
I reconnected the plug anyway just in case.

Anyway the net result is the diesel filter is now done and I feel pleased with the result.

Thanks - Paul

Paul, I never posted any photos when I did this: did you take any? It might help the next one of us that tries this job.

Thanks
