Just thought I'd add that there is a bush that need replaced, I believe its the passenger side wishbone which is gone and when i brake theres a thud, so theres more play in the road wheel? This is getting replaced for the mot in a few weeks but I just wondered would this have anything to do with the wheel alignment and steering sensor which can cause esp/asr? Probably not as it would cause the "fault" more often?

I knew when I got the car there was a problem with this its just that its now colder weather lol. I've read a few threads but they all seem to be a bit different. The problem is the drivers side temperature does not change temperature on either hi or low and anything in between. 2005 c5 estate 2.2 auto exclusive. The blower blows fantastic and does everything it should. Passenger side works perfectly through all the range from really cold to really hot. I keep it on auto with the passenger seting at hi and it sort of stops it blowing full cold air out one vent and the car does warm up. Its more of a pain than anything and if its dash out I'll just forget about it. Am I right in saying there is a motor I could replace which is on the drivers side bottom motor which is broken?

Thanks Paul. Just got time to look at this and the parts that you have listed or not the same as the one in the photo as they only have 2 pipes coming out the top and it looks like there are 3 valves related to the egr? The one in the pic I attached has 2 at the top and two at the bottom but the guy is not sure if thats the turbo vac solenoid.......i cant find it in the parts diagram. Just to add I have a blanking plate on my egr at the pipe coming from the top of the engine, i dont think this is causing a problem but really do wonder should i remove it? I have noticed that since the maf has been cleaned and i replaced the air filter that the engine management light does not come on as well now when i get the fault just the service and esp/asr light. With all the help and reading I now think its down to a duff turbo which I dont really think it is, the turbo vac solenoid or the particle filter? I would get the dpf removed in a heartbeat if I was sure that this would cure it but I dont have the money to do that and then be told its the turbo if the fault continues. Thanks for everyones help so far btw. I've also got a heat problem lol but I'll do a new post for that. Strange thing about all this is I love the car lol and would like to keep it but dont want a huge bill of a new turbo hopefully. If I could identify what this valve does and its worth a shot I'd get one and stick it in.

Another question and an update. Havent had a chance to go to a dealer and just been putting up with the fault but spent some time on the car last week. Replaced the Map and still the same. Had a smoke test done on vacuum and it was fine. Bought some fancy MAF cleaner and talk about a difference! The car has always been sort of sluggish but having not driven another one I thought it was just the size of it but how wrong was I. The acceleration is fantastic and is sort of like a new car......still getting the esp/asr fault but no where near as regular, can go for a couple of days before i see it but now get depolution fault on screen as soon as i start the car. I havent had the fault codes read in a while and will get this done again next week. I've been told the vac solenoid could be faulty and was wondering if the pic i've included is it? There is a c5 the same as mine in the local scappers so should be able to get this part quite cheap and was going to give it ago. I realise that I need the fault codes but was just going to give this ago anyway. Pic is here ><img src="http://www.myalbum.co.uk/Photo-MO3H6WHX-D.jpg" border="0"></a>

hmmmm, the faulty wiring thread must have been a nightmare! I will get it checked ifs thats possible but its hard to understand why the wiring would do this only when the car is under load from the engine.... Latest now is I took the car back to kwikfit and they redid the alignment. The tech guy there who is a citroen master tech spent about an hour with the lexia and he thinks the car needs a turbo and the comms 2000 is not causing limp mode as it only happens under load. Kwikfit were pretty good with this and redid the alignment and the diagostics and only charged a £10 as I had the alignment done in a different branch at the end of june. I'm not sure what to do now, different options, get the wiring checked first/go to citroen and get their view/change the comms 2000 anyway/get the smoke test done/get a new turbo or all 5. Apparently the turbo is prone to failure on these cars.......just thought.....maybe trade it in, problem is I really like the car but cant decide if its worth spending a lot of money on.

I was hoping this was a cheapish part but not so....I'm wondering how this got disturbed doing the wheel alignment, I think I'll need to check that any wires going to it or ok first! I guess a scrap yard part wont do? I'll need to get a haynes manual as well. Is there any sensors that are related that could have been knocked/damaged during the wheel alignment?

The car is indeed a 136bhp 2.2 auto. Brought it to a guy with a lexia today and was able to establish that the dpf is regenerating and no faults from the egr at all. After checking everything he thinks the steering wheel sensor is faulty as every time he recalibrated it and cleared the code it came back up as needing calibrated.... So need to get the steering sensor fixed and go from there. He thinks the turbo overboost could possibly be a red herring at this point but he's not ruling anything out at this point but he's right about the wheel sensor being the first thing to do. I'll keep the thread going and update as I go. Thanks up to now for all the input guys as it does help. Joe

Just checking, I've the egr blanked off which I'm going to remove but I'm assuming this has no impact on these codes?

I didnt realise the snapon wasnt up to the job. Just thinking that given that the car is going into limp mode would that not suggest the turbo pressure sensor is working? Do you know what a dealer would charge for such tests and am i into big money if its the turbo?

Ahh, thats probably right about the pics, cheers. Had another guy put the car on a snapon and it came up with p0380 preheating relay circuit , P0234 turbo pressure regulation, P0235 turbo pressure signal. He advised disconnecting the maf and see what happens which I did but the esp/asr came on as usual around 2300 rpm so I'll connect that back again. He said he would like to do a smoke test on hoses first and then if not that its most likely a sensor and its not the dpf/egr. I'm bringing it over to him on Tuesday. He says to do the cheap stuff first which sounds good, i'm hoping the turbo is not chinned........ What do you guys think?

Thanks guys. The site wouldn't let me upload the pic of the results and I just typed the first column however it would appear it's not right anyway. I'm getting it back on a proper diagnostic tool today and hopefully get a proper indication what's up. I have never seen any dpf error messages hence my reluctance to change/remove the dpf. I hope I get better info today and believe I need to go into the Asr sub menus if it's wheel related. I'll post the results of the test later but thanks for the pointers guys.

Hi Guys I realise this is an old chestnut but if anyone can help it would be appreciated. I have a 2005 2.2 C5 estate elegance. Full service history up to 100k and I've put 7k on it. Got the wheels aligned about 8 weeks ago and that started the sadness. Got the esp/asr and into limp mode. Got the steering calibrated with a snapon and still the same. After reading on this forum found the swirl valve rod was broken and got the new intake swirl valve fitted and still the same. I got the egr blanked off at the top of the engine and tried that no joy. Problem is getting someone to tell me its defo the dpf or egr is hard. People tell me its that others say its not and everyone wants to charge but wont guarantee a fix.....to get the dpf/egr delete is £360. I dont mind paying that but would hate to do that and its a turbo for example. This is what I do know and I used an ebay lead and some software tonight to read the codes but nothing much came up except P1352 which it says is ignition coil A primary circuit.......previous to that I was getting turbo overboost P0238, P040, P0400. Btw, the car does mostly motorway driving and at that stage 200 miles a day. Dont use it now for that until this is sorted, my trusty mondeo with 160k is still saving the day lol. I was also told to check stop light bulbs as this can cause this error....I did and low and behold I had a rear stop light out which I sorted last night. Same esp problem but only this P1352 code now.... I ran the laptop on a quick run and got some data but I havent a clue if its any use and was wondering if any of you guys could have a look and give me your opinion if possible? The car starts great and can drive for a few hours or 20 mins and then beep beep hello limp mode. The eoyls was filled in Oct, full service as well with a stealer. I'm going to try another mechanic tomorrow for his tupence worth but I really would value any suggestions from you guys save burning the car lol. Just tried uploading the pic but getting a server error. Heres the detail; Calculated engine load 29.8 Intake manifold absolute pressure 103.0 intake air temperature 58 air flow rate from mass flow sensor 11.77 fuel rail pressure 25300 Thanks

Thanks, I guess I was just looking average mpg from drivers of the same car.

Hi Guys I have some stuff posted about this car in a different thread (model and year in Topic Title) but having decided to buy it I am now concerned about the MPG. If I can get around 30 urban then ok but can recent owners tell me the "real" number please. If its less than 30 around town then I wont buy. I need around 30 in town minimum and 40ish motorway. Thanks Joe

Just wondering what sort of mpg would you get with this model? I'm not sure what the brake horse is, its described as a C5 "tourer" 2.2 hdi exclusive 2005.
