Xantia HDi fuel filter changes

lolingram · Post by **lolingram** » 22 Jan 2007, 17:21

I own a 1999 Xantia Estate 90bhp HDi with 198K on the clock, which drives very well indeed (and is most frugal) - I bought it at 190K well worth the money.

Looking back through the services (not Citroen Main dealer maintained), one can see that has had a pretty uneventful history, with no distasters to date. It was on long term corporate lease by the first owner (until around 100K), and has clearly had a pretty easy going life nothwithstanding the mileage, and has been serviced every 10K miles since new by a mixture of small garages.

Given the horrific tales of HP pump and injector tales on this and other forums, would I be well advised the change the complete fuel filter unit, rather than just the filter element? Any other horrors likey to raise their ugly heads at this sort of mileage that are avoidable given hindsight?

Any advice much appreciated.

Quite simply follow the manufacturers destructions. I would also speak to the servicing agents and ask for the service history in detail (on compter records)and that will tell you what is coming up or late in attention needs?

Clearly, but other than the obvious, I was thinking essentially of fuelling problems that only apply to CR - are these necessarily mileage/time related? Is fuel filtration much more important, and if so, the best way to attack this correctly.

Hi,

Have a read of this thread.

Bare in mind that if the PSA had got it exactly right a disintergrating lift pump wouldn't destroy the whole injection system as some have found to their cost.

Seems Ford screwed up in this respect as well...

I meant to say thanks for the links.

Would a GSF lift pump be reccomended, or should one opt for a genuine PSA spare seeing how critical is the issure here?

Based purely on speculation I'd say it makes no difference who makes the pump, when/if it fails it kills the injection system. The general thought on this is that a fill up of the wrong fuel (petrol) is a timebomb waiting to destroy the pump, though there's no hard evidence. I'm going to get a VW filter and plumb it in after the standard one if possible. Hopefully this reduce the chance of fuel waxing and if the existing filter starts to fail this will be a good backup.

Would it not be possible to place an inline fuel filter just before the main pump just to be sure that no crap reaches the main fuel pump? There are inline filters that can be used that are clear, so that you can see what is being trapped if anything at all.

An in-line filter is nowhere near fine enough to protect a high pressure diesel fuel pump. The Bosch unit as fitted to the VAG diesels is one of the best filters I've tested.

So changing a currently OK lift pump on spec may not necessesarily be a clever move in your opinion?

A VW filter would be a lot cheaper and probably safer.

Available online, or only via VAG?

GSF would be a good source. If you can call in then you could identify which one should be the right type. Sounds as if one for a 1.9 TDI mark 4 Golf should be about right. I'm currently trying to find some images.

The main thing is finding something that's a proper filter not just a water seperator and it must stand up to the pressure of the lift pump.
