Xantia 2.0 HDI 2000 160k all motorway

kamikizzy · Post by **kamikizzy** » 13 Dec 2006, 15:26

Any help would be appreciated as I am at a loss. One day I was coming back on the motorway and lost all power had to pull in and get towed in I had the car diagnosed with a faulty high pressure pump had this replaced and took car home 90 miles faultless parked up same problem turns over but will not start . I call AA give him key he turns it over starts first try so I feel a little embarrassed but he checks it over and says its ok so I turn it off and leave it till the next morning… As you can guess it turns over but will not fire…so it goes back to the dealership… replaced low pressure pump and high pressure pump along with a different set of injectors, tried another ECU and am now fitting another pressure sensor. But still have the same problem it will start some times but then just refuses to start. Could this be an immobiliser issue? And if so how can this be bypassed. The dealership mechanic is at a loss and its cost me a small fortune.

Personally I'd take it to a specialist, maybe a bosch dealership. or someone like the diagnostic doctor who does the column in Car Mechanics mag.

Thanks for the reply but I thought a citroen dealership was a specialist

Hi there, Even a good citroen main dealer will only be really proficient in fault finding the more recent cars.. (It doesn't mean they are incompetent, But the bulk of their work is with the latest models after all). You don't say where you are, but a trawl on here for an independent citroen specialist near you may bring better results. Because they deal with the older cars they have built up a vast knowledge of the problems and foibles that arise with a higher mileage. There is a thread on here somewhere giving all the Citroen independents, if I can find it then I'll put it on under here. Hope this problem can be solved without too much extra cash -best wishes, Martin

Just found one you can have a look at !

With respect to main dealers they have to fix whatever come their way where as a Bosch dealership will have access to all the diagnostic info for all types of Bosch systems. Also bare in mind they will specialise in electronics and/or fuel injection systems. Usually such places are real experts not just plug it in and see what it tells me to do merchants.

The Citroen Car Club (UK) maintains a list of good, bad and ugly citroen specialist as recommended or otherwise by their member direct experience.

Good Luck.

does it show any other symptoms when it doesn,t start i.e unusual dash behaiviour - I had a similar problem with intermittant starting which turned out to be a wiring loom problem which effected the supply to the shunt fuse in the dash fusebox. I also saw other symptoms as the shunt effects a number of things apart from the immobiliser but as it doesn't cost time or money it may be worth checking the voltage on the shunt at a time when the car wont start - it needs to be full battery voltage

Hi all thanks for the input I shall have a look at the fuses but it was showing nothing abnormal as far as I can tell. just thought if it was possible to bypass the immobiliser that would at least eliminate that.

The Citroen dealer has fitted 2 high pressure pumps, 1 low pressure pump and a set of injectors and the fault is still there. Am I reading your post right? I suppose they told you all these expensive parts were needed and have not refitted your probably ok old parts back again after the new ones failed to cure the fault. I bet it would almost have been cheaper to scrap the car and buy another one compared to what the experts have already taken from you.

boncechop: fair point there... my bet is it's almost certainly an electrical fault, usual problems are earth points to major electronics for the car, take a good look under the bonnet, paying particular attention to areas near the bulkhead where you find fuseboxes/ecu/looms, go round spraying some wd40 will do no harm either... failing that take it to a bosch specialist, good luck

Its not been sorted yet but I will post a reply when it is oh and this saga has been going on for 13 months now but I think it may be down to the fitter who never bothered to clean the fuel system out when the other unit faild or thats what i have been told.. so they are fitting a new fuel pump today heres hoping: and ya right about the bits all along i said it cant be this and it cant be that because it ran too well

Sounds unlikely as many years ago manufacturers started fitting decent filters to diesel cars to protect the expensive and delicate pumps from just this problem.

Funnily enough there's been a thread on Honestjohn about this problem. It would seem that it could be down to the fact that because it's a 'insert' type filter rather than a spin on there's a possibility that some particles can be left behind when changing it - hence the piece in the Haynes book about cleanliness. Also according to some the housing itself isn't strong enough and bulges under lift pump pressure (some claim to have witnessed it), if this is the case then maybe fuel can bypass the filter altogether. In view of this I asked if anyone knew of a suitable in line diesel filter.
