i certainly doubt it needs a new flywheel for starters they are taking the P :D

well ask them to put it back together without doing the clutch then get another garage to change the clutch at less than half that price £650 to fit a clutch is a joke

that's very good news mate and its worth others remembering this for future reference when it raises its ugly head in the future :D

because its a 1998 doesn't mean it has hydro mine is a 2000 and still has the mechanical pump ( a quick look under the rear end will confirm this as the none hydro only has 3 spheres and the center one holds the suspension up when its left for any length of time not like the BX that sinks when its off hydro works when the key is in the ignition without the engine being on because its electronically controlled, the part you need is about £20 and a simply replaced, this is a picture of hydro type and ive put red arrows to the parts you need you will notice there are more spheres on the hydro type than yours so ignore them in the image yours will only have 3 http://i469.photobucket.com/albums/rr53/te...ntiahcupd-1.jpg

are you sure its hydro active? difference is that's electronically controlled and the none hydro is driven by the engine via a manual pump, if its the none hydro then it sounds like the link arm connecting to the rear anti roll bar has snapped this gives you no height on start up but you can shift the lever to raise it up to full height ( the link arm is next to the height corrector driver side rear )

code is 650 fuel shutoff solenoid faults could be wiring relay module, coded key pad, fuel shutoff solenoid, fuel injection pump, ECM. the solenoid is inside the pump and there is a round electrical connector with 13 pins the pins to check are 12 and 13 they are in the center 12 to earth ignition on should give a voltage between 11 and 14v and 12 and 13 ignition off should read 23 to 35 ohms

im not sure you can just replace the ECU with one from another car because the alarm and immobiliser is linked to it perhaps some one else could give better advice as the 2002 hdi is not my field

find the wheel sensor and you have found the toothed ring its directly below it and runs round the cv joint

P1112 Intake air temperature (IAT) sensor circuit Intermittent low voltage EDC15C2 - Diesel high pressure monitoring function. Pressure lower than the minimum pressure. (leak). MM4MP2 - Motorised throttle control. P1138 High pressure rail sensor fault / Lack of HO2S 2 switching - Sensor indicates rich P1138 For EDC15C2, as fitted to DW10 engines, this fault code indicates a power supply interruption to the rail pressure sensor. There was a modified intermediate harness supplied, which had to be fitted with a new sensor and harness retaining clip :D

I must admit I prefered it when no car had computers things were easier to repair but technology has to move on I suppose but the dealers use it as a cash cow just like the government and the motorist is keeping this country because the car needs repairs so the we are going round in circle's trying to keep out of debt and they do their best to put you in it :D the never ending storey ;)

your answer is very cool random bloke I couldn't have explained it better my self, HDI is not my cuppa tea I must admit but your answer has got me interested to look at it a bit more. I edited that last answer out because it was inappropriate :D

and all this can be deleted because its failed and now a cash cow for citroen/pug psa group

check the wiring to the ABS sensor and clean the ABS ring of any muck/grease, as long as the light goes out it really doesn't have a major issue and because it comes on intermittent sends my thought to the front wheel sensors since you just changed the pads, once the car is jacked up and ignition turned on then running the engine always turns the ABS light on because the car isnt on all 4 wheels so it thinks there is a problem but it clears after a short drive

ESP = ( electronic stability program ) not a sensor this is effected when you have an emissions problem and its part of the main ECU but your problem was covered in the links I supplied and down to EGR valve in most cases needing cleaning out, the FAP filter is in front of the catalytic converter which requires cleaning approx 50k miles and done by the dealer as you need diagnostic equipment to do it and the other tank is called the eolys tank which requires filling with liquid GOLD j/k but extremely expensive and it holds 1 gallon £100 ish, you need to go down the street of cleaning things out like the EGR valve to see if that corrects the problem first ( Im not saying what it costs at the dealer to fill/sort the FAP and reset the computer ) I don't want you to have a heart attack :D your problem is emissions related

its been covered http://www.citroen-owners-club.co.uk/citro....php?t3927.html also a good site for information http://www.scribd.com/doc/2530474/Citroen-Technical-Guide

this could be a known fault like oil not getting round the system fast enough or sludging as the yanks say so good engine cleaner might help like slick50 which puts a Teflon base on all the moving parts which makes the engine run smoother and keeping the idle easy but the throttle position sensor (TP ) is also a known fault with many cars and the idle control valve as they get funked up because of the EGR system which effects the running and rarely gives fault codes until it effects a main component like the TP sensor totally failing

a very good example indeed ^ but remember the code is only a guide to the fault and that's where even the dealers fall down ( or not ) as they use this to fit new parts instead of telling the truth, as I have pointed out many times like the EGR valve ? they replace it when it only needs cleaning out so its down to pricing rather than saving you money, another example of this is a vacuum line that's come off and effects the fuel/air mix then you get the o2 sensor fault code when nothing is wrong with it ( vacuum lines are not sensors so leave no codes ) but they effect those sensors in the system

its called the domino effect and you need to look at the first thing that comes into play, because newer cars are dependant on high tech its ECU controlled so software driven so its back to basics and CAN does that and very basic but that's a 2008 project which is working on I could explain this in greater detail but life is short you are a master but you don't see it yet im impressed because your honest and your a learner which is what I am we never stop learning, i ime old sod but the Internet has broadening my horizons

simple replace mate when its stuffed it cant be repaired ive been doing diagnostic for too many years and still learning :o

normally its about £80 is but worthless because they only tell you the fault and don't fix it so invest in a diagnostic tool and boot them buggers out :o ps lexia3 is crap on the newer cars ( dealer promotion ) as most diagnostics work and are cheap

hopefully you have resolved this looking at your post on the other site :o

I wouldn't buy one but I quite like it ( too small for me ) :o

^ I totally agree the older c4 is much better looking Citroen made a mistake there and they will pay for it with lower sales ( bring back the DS ) and ill buy an old one only because I hate newer cars :o

the cam pulley is alternating a bit like the old Honda vtec so when it has a problem it throws the timing out a little

P1138 High pressure rail sensor fault / Lack of HO2S 2 switching - Sensor indicates rich EDC15C2 - Fuel pressure. Stop requested but regulator still active. sounds like the fuel pressure regulator to me like over fueling? the biggest problem with this engine is HDI/HPI because its fuel pressure related and many problems come from that
