Serious Question for a change.
My Neighbour Has an Xantia X-registraition 1,9 TD HDi estate. approx 90,000 miles on the clock.
He has a problem with the engine cutting out at all speeds, it will even cut out at 70mph.
He has been to Citroens for a diagnostic's session £69 and the results are as follows.
Lexia. Temp Fault fuel High & low pressure.
Fuel High pressure Lack of pressure.
Temp fault on exaust gas recycling open circuit.
errased faults with Lexia.
Has anybody please got any ideas or suffered similar problems with a similar xantia. I have forwarded Martins details but suggested asking the forum members first as my neighbour is not online.
apparently Citroen are now pointing to a problem with the turbo and there is talk of replacing it with a new unit, which sounds a bit like clutching at straws to me and in my experience Citroen will quote you one figure and at the end of the day you could end up paying through the nose and still have the problem. they have also said something about there being two fuel pumps one high pressure and one low and there could be a problem with either.
any sound advice would be a bonus . the very same citroen garage stung me for £400 for a set of pulleys and a serpentine belt Ouch!!.
thank you in advance.

Well, if anyone looked and thought hard enough, what has the Turbo got to do with Fuel Pressure problem... The turbo makes AIR PRESSURE not fuel problems, Whats the history with the Fuel Pump in the Tank?
That and the High pressure pump under the bonnet are the two items that pressure the fuel.. Id raise my alarm bells with that diagnostic and their next procedure...

Yes, absolutely. Did the use of the word "temp" mean temperature or temporary in the context of the recorded EGR fault and first fuel pressure fault? I suspect the latter.
The meaningful one is the fuel pressure and certainly the one bringing the engine to a halt. If the fuel pressure falls below a certain level, the whole shebang shuts down to protect itself.
This quite nicely demonstrates how information given by the Lexia needs to be carefully interpreted. Quite how they interpreted a turbo fault from this is beyond me

Given that the cost of a new LP pump is about the same as a diag session at a main dealer, I'd just change the thing - this is the most likely cause of this problem. Is the pump noisy when the ignition is first turned on (don't crank it, just listen)? You should also change the fuel filter, complete with its housing - the pump tends to shed debris into the filter, and it's possible for this to bypass the filter when changing it - changing the whole unit avoids this problem.

jim, richard & paul,
the fault diagnosis was temporary and not temperature sorry I wasn't clear on that one.
As I understand it the gent is ill at the moment, I shall try to get your answers back to him tommorow.
Thank You for your help.

Clearly, whoever 'interpreted' the diagnostics has no idea.
Low and High fuel pressure faults. Both pumps need an adequate supply of fuel; the high pressure pump depends on the low for its supply - if the LP pump doesn't produce enough output (volume and pressure) the HP pump can't produce sufficient pressure.
I agree entirely with Richard and Jim - start at the beginning: make sure the in-tank filter is clean, change the LP pump and the filter. Of course you need a garage where the mechanics possess and use a little intelligence!
Where-abouts are you Nigel? Perhaps someone on the forum can recommend an independent Citroen specialist somewhere reasonably near you?

Guy,
Have recommended Martin & Pleidies, I shall print this off and pass it on today to my neighbour (Mike).
As I understand it it is a 2.0 litre engine but I translated that to 1.9 not knowing much about the HDi xantia, sorry about that.
I come back if I can get any more information today.
thanks everyone for your help.
regards Nigel.

Hi Nigel.
I couldnt find your number to call you back so here goes with my daft idea.
If you lift the back seat and remove the circular cover for the tank top, you will find 4 wires, the 2 thickest in the middle are for the pump, connect a long piece of twin wire to these and run it through to the front of the car, then connect them to a light bulb.
Now when you switch on the ignition, the pump will run and you will hear it buzz, as soon as the priming is over the pump will stop buzzing and the light will go out, as soon as the engine is running the light will come back on, if at any time during the journey, the engine stops, check the bulb. I would say that if the bulb goes out when the power goes, the pump is the problem.
Simple but it should work more precise than any computor gizmo.
Regards
Martin.

Martin,
Thanks for that, we shall give it a try. sounds pretty good.
I guess the pump does run whilst the engine is running to keep the system pressurised then?

I don't know if you're aware of this (I just speed-read the thread) but I've read some HDi lift pumps are prone to failure in a nasty way - they disintegrate and scatter lovely glitter (metal filings) all around the fuel system
If it's left to circulate, it can ruin the expensive parts so well worth checking ASAP. I think it's just a matter of looking in the filter housing? Personally, I wouldn't take the risk of running/driving it anymore (unless it's under warranty) if I owned that car with those symptoms.

To clarify:
the Low Pressure pump in the tank is effectively a fuel-lift pump to provide a continuous flow of fuel at constant (lowish) pressure via the main filter to the inlet side of -
the High Pressure (injection) pump.
Both pumps run all the time the engine is running.

Thanks everyone thus far this should keep us busy for a while.
I will check the fuel filter for any signs of metal.
I managed to have a chat with Mike (my neighbour) yesterday he says that the car starts and runs perfectly fine then whilst driving the engine cuts out completely.
apparently there is no sensation of fuel starvation no kangerooing or jolting the engine just quits completely out of the blue when it feels like it.
sometimes trying to start the car again fails its almost as though the whole car is dead, turn the key and nothing happens at all.
Now not knowing any thing much about HDi's shouldn't the starter at least turn the engine over?
waiting two or three mins usually alows you to restart the engine everything comes back to life, sounds more complicated than just a fuel pump to me, unless the pump failing shuts down everything for a few mins whilst something resets.
strange. appolagies for not knowing all at the start Mike has heart problems at the moment and I didnt want to stress him out to much.if at all.
