MAJOR HELP 3008 ECU FAULT Jump to Latest andipoke266 A hi all im a long time member but first time poster,i bought a 2010 2.0hdi 150 exclusive in february 17 and love the car,but in 18 went for mot and failed emissions,garage did full service and eventually got it through,now fast forward 12 months and i get a burning smell from air vents,told by local garage its the dreaded injector seats and its caked in carbon so bad they wont touch it,so went into my local peugeot dealer, so they decoked round the injectors and fitted 4 new injectors [i bought seperatley from pfjones £600}and a new injector wiring loom,so £2000 later i pull the car out and seems fine,for a week,then car starts running lumpy,no power,takes back to peugeot who tell me my ecu is kapputt,also need eolys tank filling,and 2 tyres for mot,,another £1800 to peugeot and 2 weeks of waiting for ecu and finally get car back,all running well, now jump forward 12 months to march,car flys though mot but advised new rear disks needed by local garage i trust,got done but then had major issues with rear wheel sensor throwing up abs/esp and other faults,finally got that sorted,was a damaged magnetic abs ring on disk,just swapped it for ring off my old disk. and then one week later i get the depollution system faulty message,eml on and car has no power but no limp mode message if it has one??, so local garage plugs in and turns out it had tried to regen 3 times in last 280 miles but failed,and apparently my 13 moth old £1100 ECU has a fault,WTH,i phone peugeot dealer who are shut but got new managers number off website who cant do anything because he only took over 6 weeks before lockdown and has furloughed his staff so cant ask about the car,told to wait until they reopen in maybe a few weeks and he will see if they can do anything but ECU only has 12 warranty, please anyone help,im disabled and car is my only transport,also wifes a care worker and i get her to work every day,have i any chance of getting ecu replace under warranty,and why would same part go like it has,garage said it was a cambus error or something 21 - 40 of 57 Posts 1 2 3

By using Enter to separate your sentences (you heard about paragraphs?), by using punctuation, start sentence with uppercase letter, etc. A

· Registered Joined Oct 20, 2010 · 27 Posts ok finally using torque lite i got it to connect and code P0488 egr throttle position control range/performance, whatever that means R

· Registered Joined Oct 19, 2012 · 15,369 Posts Thats ALL you have that does not say ecu fault That means the ecu is not liking the signals from your EGR system this does NOT mean you need an EGR valve it means the circuit is not doing as it should what engine was it again A

· Registered Joined Oct 20, 2010 · 27 Posts well that was all that torque lite found, fap lite couldnt connect to ecu at all,it was the garages that said it was ecu fault with their machines,its a 2010 2.0hdi 150bhp DW10CTED4 ,cheers R

· Registered Joined Oct 19, 2012 · 15,369 Posts Euro 6 engine then if there was an internal ecu fault ANY code reader would see it so chances are there is not i recon whats more likely is they tried to clear the EGR issue and could not so assumed ecu is faulty and told you that because they dont want to spend any time on it ! Clear the code if it will clear drive it then do another read A

· Registered Joined Oct 20, 2010 · 27 Posts i cleared code but still had eml on and depollution sytem faulty on hud,still ran lumpy and as if mixture was wrong and code came back again ,,,cheers R

reliable406

· Registered Joined Oct 19, 2012 · 15,369 Posts Ok its probably a permanent fault then so given what you have found so far my next course of action would probably be checking live data for readings of airflow and fuel then removing the egr valve to check its not gummed up with carbon which may be beyond your comfort zone its not an easy one to remove Ignore depollution faulty message it means nothing its just crap wording saying engine fault get me fixed once fault is fixed it goes away A

· Registered Joined Oct 20, 2010 · 27 Posts so im back lol,my error codes are now P0233,P11ab,P0488 and U3fff,now ive just done a wynns proffesional egr3 cleaner and given fuel a shot of wynns diesel cleaner extreme,nodifference but whilst i was at front of car i noticed that the big air pipe on left was flat,as if it was sucking but getting nothing,also made me realise that i dont think my turbos been working which explains the slow speed build up,so any ideas R

reliable406

· Registered Joined Oct 19, 2012 · 15,369 Posts If your pipework is sucking in then there is something stopping the airflow and this is probably the REAL fault could be the pipe has delaminated internally as they are double layer but its more likely a dozer flap is closed or some other physical restriction somewhere A

andipoke266

· Registered Joined Oct 20, 2010 · 27 Posts well ive just been running it at 2-3000 revs and its shot loads of black smoke out,still got all the errors and the pipe on left is still squished when engine running,im now at a loss what to do next,ive looked at pipework and think its out of my league,so anyone know if its a hard job or easier for a garage to do,i read somewhere that one of the codes could be a sensor above the pipes,cheers
