Citroen xantia W reg hatchback loses power on motorway revs drop to 2800 and maximum speed 80 mph.Have had computer diagnostic check,reports say small fault on turbo rectified by computer,engine diagnostic light still on, checked electrical point 1208 no fault found therefore problem must be the high pressure pump.
To spend £1000 fitting new high pressure pump on a therefore it must be statement by a qualified citroen engineer seems a little bit hit and miss.How accurate is computer diagnostic check in determining the cause of this problem?
Is there some other check I need to do first before proceeding?
The problem feels like it could be fuel starvation.But how do l determine whether this is the case?
Secondly how do l determine what sort of assension spheres are fitted to this vehicle?

Not coming up to 60k by any chance is it? This seems to be the mileage the LOW pressure fuel pumps pack up - which definitely gives fuel starvation symptoms, and no fault codes [}:)]
Cheaper than a HP pump, but not pennies by any means (fuel tank out IIRC)! I guess it should be possible to engineer a means to measure the LP fuel pressure, but I don't know what it should be!

I'm with Richard; sounds like the old "HDi low pressure pump" problem which does get documented now and then...
Assension spheres...I like the description , but "Suspension" spheres they are; There was a very long post on spheres very recently (I think V6 or activa related) with pressures/part numbers/applications galore!

it sounds like the car is in limp home mode as it wont rev above 2800rpm,a faulty LP pump is unlikely to cause limphome mode,as richardW says it doesent bring any fault codes up when this goes,however a 'small' turbo or turbo pressure fault will cause this.
when you say you checked electrical point 1208 you mean the piston deactivator on the HP pump ?
