Xantia HDi lift pump
Looks like I might not get to 200k of Xantia-ing without a ride on the back of a wagon....
The lift pump has always been noisy on this car - then yesterday morning there was a bit of fluctuation in revs at start up for a few seconds, this morning it ran OK, but the pump was quite noisy pre-start. Then 500yds from work all the lights came on and it coasted to a halt Refused to re-start and there is only silence from the rear Odds on then that the pump has finally thrown in the towel - well it's done 140k and 12 years so I can't really complain!
Now, where abouts is the access hatch? I lifted the front of the boot carpet and the carpet under the seat, but it didn't reveal itself. Is it right on the top rail under the front edge of the rear seats? Do the seats need to come out? I was thinking if I could get the hatch off, I might be able to give it a thump and get it going so that I could get home again (albeit in stages maybe) without having to resort to getting a ride.
Replacement pump supplier?

Re: Xantia HDi lift pump
Oh dear Richard
The access hatch is under the driver's side rear seat base under a big round rubber (plastic) bung. Once the seat base is up you then need to lift the flap of carpet to see it. Should be no need to remove the seat though...

Re: Xantia HDi lift pump
Richard,
I had similar experience on my Xantia, it refused to start in a multi story car park. Almost in desperation I hit the top of the pump with a rubber hammer that was in my tool bag although some people have suggested a hand slap underneath the tank.
It was enough to 'wake up' the pump and it continued working for the few days necessary until I bought a replacement from GSF.
I've since seen on ebay various sources for this pump, listed 2 of them below
271108182666 £51 inc p&p replacement pump only. This could be fiddly to fit because it is only the pump element of the whole unit. It is cheaper though and carries a 3 year warranty ( wish I'd known about them when I had my problem ).
390389071444 £120 inc p&p . This item is the compete pump/fuel gauge sender unit.
I'm sure you will have seen other posts on the forum about checking the fuel filter in the engine bay for debris, usually brass dust, which is produced when the lift pump in the tank begins to fail. If anything gets into the high pressure pump the result is usually severe wallet damage
Happy spannering

Re: Xantia HDi lift pump
A ha - found it under the front bit of carpet after I levered the plastic cover off the seat mountings - with the only thing I had to hand, namely a shovel . A bit of discussion with it with the wheel brace and she sprang back into life. Diagnosis confirmed
Hopefully we'll get home without it needing another seeing too - time to order a new one..... Already spent over £500 on cars in the last month. Ouch

Re: Xantia HDi lift pump
Hmm, occasionally if I turn the key for too short a time on my V6 and the engine doesn't quite start I hear a noisy sounding fuel pump (I assume that's what it is) from the rear of the car slowly spin down over a period of 5 seconds or so....should I be expecting trouble with it soon too ? Most of the time it doesn't make any noise so I'm baffled as to why it occasionally makes a slow, dry spinning down sound over such a long length of time, and yet is silent most of the time...(I've only noticed it 3-4 times)

Re: Xantia HDi lift pump
Nope, nothing to worry about at all Simon. you'll often hear funny sloshing and other noises from the tank pump. Sometimes they can sound very alarming but all is absolutely fine.
I believe it might just be turbulence in the swirl pot.

Re: Xantia HDi lift pump
Wagon it was.... only got a couple of miles from the office before it died again, and wouldn't restart.
Got a new pump on order from carparts4less - £82 for an unbranded affair - and £10 off that with their current offer, so not too bad. Looking forward to changing that in the current baltic weather

At least you can work on it inside the car Richard... Pop a fan heater in there and it'll be quite cosy...RichardW wrote:Looking forward to changing that in the current baltic weather

In which case I would take out the lower part of the seat, to have a bit more elbow roomCitroJim wrote:At least you can work on it inside the car Richard... Pop a fan heater in there and it'll be quite cosy...RichardW wrote:Looking forward to changing that in the current baltic weather
Just two nuts to remove once that plastic cover is off.
On my car those are just finger tight as I've taken that part of the seat off a few times. Very handy for one or two unusual loads.

Re: Xantia HDi lift pump
Hadn't thought of that Jim. Even though I have a fan heater in the gararge for defrosting the cars! None of that grafting scraping cars round here
I would take the seat out I think - it keeps falling down on the job. Has it been drinking Wonder how easily the plastic ring will let go after 12 years....

Re: Xantia HDi lift pump
In my experience the plastic ring is more of a problem to get back on than to take off.
Man is, by nature, a lazy beast, he does not need twice encouraging to do nothing.

(it won't fall down if you move the front seat forward)
But it's very quick to remove anyway.
I haven't looked in there myself so don't know what type of plastic it is. Would pointing the heater gently towards it help at all?Gibbo2286 wrote:In my experience the plastic ring is more of a problem to get back on than to take off.

Re: Xantia HDi lift pump
It was sunny but cold here today so I stuck the new pump in this afternoon. Took a fair bit of persuasion to get the ring moving and there is only just enough room to wiggle the ring and pump out past the fuel pipes. ring went straight back on - but then I did clean it and grease with vaseline before attempting. Engine fired up straight off Anyone doing the job is advised to have a bit of tube and drain tray on hand - the unit body fills up with diesel and has a one way valve in the bottom, and the pump needs to be tilted to clear the fuel gauge float, so it needs to be emptied a bit to avoid it slopping out. New pump is very much quieter than the old one ever was!
PS Engine management light is on - presume it will go off after a few starts, otherwise will have to call on Mandrake to turn it off

Good news that it's going again.
Reminder: have you had chance to check fuel filter?
