HORRRAAAY HORRRAAAY the c5 just ran all day but i dont want to speak to soon. Went on a course for the canbus and ecu systems on tuesday and the guy that was speaking to us is one of the top men in the country. so at the end when he asked if we had any questions so i was off like a rocket to the front and explained about p1138 anyway he stopped me and told me that the fault was down to 1 of 2 things either the injectors or a bio metal strip that the early c5s had in the fuel filter housing anyway straight into the garage and swapped injectors over car ran 2 hour and ping back it came p1138. So next we changed the fuel filter housing and the car has now been on the road working for 2 days so heres hoping. Out of curiosity does anyone know what this bio metal strip is and does as ive never heard of it

Hi sorry for delay at getting back to you but weve been flat out. anyway swapped the intank pump over and car ran for 3 hours and fault codes back on. cured the car cutting out that side of the problem turned out to be the fusebox where the multiplug goes in move it about and the engine was cutting out so that side of it has been sorted so now the problem is as follows clear code p1138 and start the car up .we can now run the car for as long as we like and it will tick over as long as we want it to providing we dont turn it off. when we do turn it off the engine will then run on for 2 to 3 seconds before it stops then when the car is started up it comes up anti p/f and puts the light on and code p1138 is back. so my line of thinking is now as follows 1 the injectors arnt shutting down straight away and still allowing fuel in 2 its running on due to oil in the pots (the car doesnt throw any smoke out or use any oil) any thought please

ok stripped harness back an replaced the wire put car back on road no fault codes present ran 2 hours then came up anti pollution fault and code p1138. anyway the snapon guy came round last night and scanner was updated so when plugged in it is now stating that p1138 is the fuel pressure regulator which is what ive been told on hear but the pressure regulator has already been replaced and new wiring so up to now this is what happens p1112 replaced AIT sensor car ran 8 hours b4 fault came back along withp1138 Codes cleared car ran 2 hours then faults came back Fuel pressure regulator changed car ran 4 hours then fault back(not p1112 this time ) Wiring checked and repaired car ran 6 hours then fault back Fuel rail sensor changed car ran 3 hours then fault back Fuel filter changed car ran 3 hours then fault back all pipes have been checked and wiring/multiplugs etc code p1112 has just disapeared altogether and just left with p1138, at first the car was cutting out when the faults apeared but now it still runs so there has been some improvement. Could the fault be inside the high pressure pump where the regulator sits. untill the fault appears the car is perfect with bags of power and shuts down as soon as you turn the key and when fault is on car is sluggish and when key is turned off the engine runs for 2 to 3 seconds before stopping

hear what your saying and have read about the wiring upgrade for the loom but (and there always is a one) my local dealers are saying that there isnt one and theyve never heard of it. So is it a case of cutting down the loom and checking every inch of the wire or just replace the wire regardless also is there any kind of shortcuts or do"s and donts that you know about cheers

With the anti pollution fault and engine management light on its the same reading apart from the fuel pressure regulator which reads 17although once or twice it has shown 1. anyway by these readings have i got a fault on the high pressure pump as the pressure is not constant at 3000 rpm also is there a fault on the injectors weve tried a new fuel filter in today and the car ran great for 2 hours then up it came p1138 undocumented any ideas

aaaaaaagggggggggggghhhhhhhhhhhhhhhhh car has ran now for 2 days then went and broke down again tonight code p1138 back again.guess i spoke to soon anyone got any ideas

got it got it got got got got it. it was a wire in the harness that had been rubbing up against the plastic casing and eventually ended up breaking in 2. dont ask me what wire it was as i just dont know only no that the car is now running and theres no codes showing up., so after 3 days and 3 parts ive now learnt that when a code shows up it dosnt mean that the sensor is knackered what in fact it means is that the sensor is working fine and has detected that there is a problem on the system that it is monitorig, but sensor must screw up so could someone more experienced than myself tell me a way to test a sensor and how to find out what voltage should be going to each sensor

changed the pressure regulator on the back of the pump and still no difference anymore ideas just to sum up the car keeps cutting out and comes up with the following codes p1112 and p1138 clear them and car drives 2-3oo yards and cuts out steps taken so far replaced maf sensor/ait sensor/diesel pressure regulator ckecked wiring and pipes all secure and intact and no leaks any ideas at all

Just wish i could learn a bit faster though. Anyway would that cause the p1112 code aswell or is that another issue. Replaced the ait sensor and m.a.f and it ran for 2 days and now cuming up aswell

only been doing the diagnostic side for a year now so im still learning so bear with me. would that cause the 1112 code to appear as well and does the regulator have to be coded in or just a simple replace

got advice earlier on this week on this week about p1112 and car was fixed. been on the road 2 days now and done 600 miles and it broke down again today. so we plugged it in and guess whats back p1112 and hes brought his friend p1138 along with him both codes cum up as undocumented so the scanner dosnt say what they are. this time though it will run for 2-3 mins then cut out clear the codes and it fires up again also if you take the key out the engine runs on for 2-3 seconds before stopping. checked for loose/blocked/split pipes and all wiring in place/unbrocken/secure any advice taken. have got a car that im breaking so i have every bit that can be swapped over b4 buying so will try any suggestions cheers

My apologies for doubting you are both right replaced sensor and car now fine. many thanks steve

The scanner i use snapon ethos displays the iat and airflow codes and is saying that there fine and working. when it shows a code though up it tells you what the code relates to. thanks for tryng

Hi its the motor (stepper motor) on the back of the speddo that goes. The one of the rev counter will swop over and put the speedo back on. just dont bend the 2 white clips that hold the motor on or youl shag it and have to get a new cluster just gently open the clips on the motor and pull it of. to put back on just gently push ito place after youve lined the 5 pins up

Car broke down today display shows anti pollution fault so towed back to garage plugged into scanner with personality key. fault code p1112 undocumented code came up cleared code and car started ran for half hour then came up with same code and stopped cleared code and started again now in a cycle of clear code=start=runs=stops=same code again. any ideas as to what p1112 undocumented code is cheers

pour some washing up liquid round the injectors and if there leaking youl get bubles frothing

id get them checked as they dont like bio fuel anymore than the pump does

hi if you look at the air trunking coming from the air filter youll see a grey multi plug going to the mass air flow controllunplug the multi plug then try the car and see if theres any difference if theres not then youl need a new one as thats what it sounds like

have you had the injectors checked

push the battery towards the windsreen then lift the side closest to the hedlight and pull out. the battery has a lip on in and slides into a recess

Real easy to fix this one. Dont take as long for your dinner then the eco mode wont be activated

Try ebay or the scrappys petrol one is the same as the diesel

Electric window switch any parts department will know what your talking about. and 80 quid plus vat for a 2 switch version that was last may

HELLO I wouldnt bother to much about the inlet side because if it soot that your seeing then that indicates burnt fuel so itl be on the exhaust side
