i have a Citroen Xantia Feb 1999 hdi....great car but it go's into limp mode on a run.....around town it is fine...but on a run it go's to 2000 revs after about a hours drive and that's it ... ...also the light on the dash comes on with a picture of an engine....if i stop and turn it off and restart its ok again. any ideas s
I had similar problem with my 99 HDi Xantia, the 110bhp variant.
In short, it's still not right a year later.
Engine would go into limp home mode anytime I revved it above 3,000rpm.
Diagnostics registered a turbo vacuum fault. Garage had it for a month, replaced the EGR valve, the turbo actuator, and the intercooler.
Since getting it back, I've only had it happen around three times, but that's maybe cos I tend to avoid the upper rev range these days!
I've long since resigned myself to the fact it's just one of these things that I can throw a fortune at and never get to the bottom of, the work so far cost me £1,500 and it just isn't worth spending any more on a car worth about 700 quid!
Car still drives, but doesn't have anything like the grunt it used to. I'll just adjust my driving style to avoid overrevving too much and drive it till it dies!
I hope your problem proves easier to solve! There's a similar thread in here about the HDi in a Peugeot 306 at the moment too.
Keep us informed, if it gets solved, I might just have another crack at mine!
it is the 110hp.....every thing i have read on the internet about this problem sounds like i have to take it to a garage and let them charge me for guessing as most poeple dont seem to get the fault fixed. i have good mechanical knowage and have serviced the car.....another problem i have is i am in spain with the car and dont intend to return soon ,so may have a problem explaning the fault due to my lack of spannish......p
Getting similar issues with my 2000 Xant Hdi 110 @ 95k miles. Fault codes are P0243 & P0246 both apparently associated with turbo wastegate solenoid. Local French car specialist (Tony Brooks Northampton - no reason to shame but mods discretion if they dont want firm named) have been very good. Explained codes and clearly suspected problems wih turbo pipework rather than component being fingered by the ECU.
Car in for second visit yesterday (first time they tested wastegate and all pipework junctions, cleared codes and asked me to monitor) when they found and replaced a split pipe. Now running normally; got one illumination of the K light while testing on the M1 yesterday but without any limp and without the light staying on beyond next restart.
Due in again at month end for MoT etc when I'll ask them to check again.
Ran OK from Sept until last week on a diet of station runs plus a trip to Leicester. Last Friday's Silverlink driver strike sent me to Wellingborough and got another K light illumination during a firmly booted overtake on the A45.
Diagnosis this time was "Manifold absolute pressure sensor incoherent - sensor or ECU fault". Sensor replaced at cost of £140 fitted. I've really tried to provoke another K trigger without success so hopefully now sorted. Garage suggest that if it does occur again the ECU is suspect and will need to be removed for testing.
Frankly, given that car is retired as family transport and functions as station hack/backup I'd be inclined to ignore any warning that did not invoke limp mode.
Is the MAP sensor the one that's on the top edge of the intercooler on these? Just curious as I have a Xsara with this engine and although mine is ok at the moment it would be useful to know for future reference.
Thanks screwloose. Yep mine's the RHZ and has the sensor on the intercooler. This same problem came up on the CXOC forum a while back, at the time I tried to find the location of the MAP sensor on the Autodata CD which very helpfully showed it as being somewhere miles away from where it really is . . .
