Peugeot 307 1.6 HDi 9HZ 2004 - EGR valve fault #

Posted by Bradley Kingsley on October 9, 2013, 10:42 pm

Year of Manufacture *: 2004
Engine Size and Code *: 1.6 hdi 9hz
( Optional ) Scanner Used: solus pro

I have just bought this for my wife as a economical runaround for her. 78K on the clock fsh

I realised i had a small misfire so gave it a full service including fuel filter and filled it with tecnotron conditioner and also flushed the oil with forte engine flush.

This did completely cure the misfire, however 30 ish miles later and the wife stopped outside to give me my dinner and the coolent fan stayed on even with ignition off. The temp gauge was only at 70oc.

Anyway off she went within a few yards after starting the eml came on and the the power died lots of smoke and then it stalled. plugged in to find 2 egr codes,, position and flow. (sorry never took a copy as had customers waiting) one of these codes wont clear , car will run and only just limped home with lots of revving and stalling on the way and smoke.

Could someone let me know if i blank the egr will it recognise the flow difference? will it need remapped?, is this most likely clogged due to soot build up, misfire or turbo probs?

Any experiance on these engines will be welcome
regards Brad

Is this fitted with a DPF??

Not saying this is a turbo issue but !!

engine flush could have had an influence

Will need to mapped out for sure.

Think i need to have a closer look at things, however i removed egr valve tonight and i believe it had stuck open slightly with far less buildup inside than expected. A bit of dry crusty build up around stem but nothing like what i expected. Think i will take the egr pipe off though and get a peek into the inlet manifold before i go further. Turbo bearings feel good. If it dont look good i think i may remove sump and get modified pipe and new strainer anyway.

Im pleasantly surprised with what i found in egr i expected a sticky black mess.

Thanks for all the info, its first class.

Hi Bradley
have you checked the inlet manifold as they are usually gummed up pretty severely, have you checked for an induction leak & does the impeller spin freely with no movement if you push & pull the shaft?
the egr will need to be mapped out & as previously asked has it got a dpf?

Should be able to check inlet tommorrow and i have checked turbo at inlet side it seems fine and yes it has dpf with fuel cap sensor but it could have been mapped out.
My list of things to do is replace cleaned egr with a blanking plate included. check turbo oil flow and check condition of inlet manifold.

If all is well i will leave blank in egr and run it for a week or two to see how it goes.
If i suspect debris and carbon build up i need a modified oil feed pipe and new strainer then run for a bit and see.

Does this sound a good plan?
Thanks again for all your help and info

Hi again a quick update,
Got inlet off and cleaned it it was a bit messy but certainly not enough to be a problem. Took cover off rocker and inspected and there seems to be no carbon build up at all. Removed no 2 injector which had a small leak and re seated, cleaned up and replaced to proper torque. Replaced timing belt and pulleys while i was at it, blocked egr and replaced in a clean condition.
Started it up and it runs fine altho there is a small whirring bearing noise.(no smoke) I think i need to check turbo flow for piece of mind next and possibly remove sump. Not sure but the whirring at idle may be turbo but cant hear it on inlet side so may need to remove outside of inlet snail and listen.
sorry maybe a bit more than a quick update but thanks for reading anyway.

Hi Again,
Thanks paul nice to know, did the EML come on after a bit?

A quick update i started it from cold this morning and measured the flow from the turbo outlet , in 60 seconds cold at idle i caught about a litre of oil.
My guess is thats a good amount of flow??

I finished putting it together and took it a drive (after clearing the codes) It seems to be performing very well with no DTCs or EML.

Im gonna give it a couple of hundred miles to settle and throw a engine flush in then change oil again.
Watch this space

OK Just adding to this message now!

2 days driving have passed (80 miles) and on the light has came. (when my wife was driving)
she says it lost a lot of power im guessing thats because of limp mode as its fine again after it was stopped and started.
Read codes with my eobd scanner.
codes P0409 P1162 P0489 P1351 P0401 were there.
I know most of these are egr related but are they all in your opinion??? I am finding that quite often the cooling fan will run full blast even when you leave the car locked. after 5 or so minutes it will turn off.
king regards again Brad

hi Bradley the light has never come on since I blanked the egr, I purchased it on ebay very easy to fit as the holes are slotted so just loosen the valve and slide in, my car has done 78.000 miles I blanked it off about 2 years ago and no problems, just been to blackpool the weekend and the fuel moniter said it was doing 64mpg, my fan too runs for ages some times apparently its a common fault with fan relays sticking,ive never had the battery go flat so have left it

Thanks paul,
mine is still misbehaving, clear codes and 5 miles later i get eml and limp again. cycle the ignition and get power for about half a mile before limp hits again.
read it with launch today and got
6 codes.
1. dust filter(fap) maximum number of regens reached. 2. pre post heating relay
circuit relay controlled and spark plugs not supplied. 3. EGR circuit air flow measured higher than the reference value. 4.EGR valve circuit too much egr, egr valve too open in relation too the reference value. 5. EGR solonoid valve sticking of the valve while driving. 6. EGR solonoid valve sticking of the valve on programming its values.

Not sure if all this refers to egr tho now i look at it? Havnt had the launch long and just noticed it has no code numbers on the printout?

Get it on Planet for a global read, so we can make sense of the codes.

It won,t do a re-gen if there is a glow plug fault as per no: 2

Its just the basic peugeot that came with x423 pad we have only had it a couple of weeks so still getting used to it.
I got a quote today to get dpf and egr mapped out im thinking of going down this route.

I will remove the dpf myself but he said its a good idea to remove the cat at the same time?
However im not sure how this could stand with its mot imissions?

Can they pass with cat removed??

Hello Bradley, with regards to passing the mot, you shouldn't have a problem. The smoke test is the same for this as it for any diesel- be it an old escort van or a new merc. It could be failed for a "catalytic converter not fitted where it had one fitted as standard" or words to that effect but how is the tester to know. Even if there's a big square welded hole in the cat I'd have to pass it!

For the record, No it can't, this only applies to Petrol, to quote test manual

I normaly leave the cats in and just remove the dpf, some turbo's will over spool due to lack of back pressure, then you have to start messing with the DC tables.

Thanks for all the input its much appreciated,
I cant make my mind up whether or not to take the cat out.
The for taking it out is less chance of it blocking or breaking up in the future and also hopefully a bit more power and economy?

The against taking it out is less back pressure causing turbo problems.

But once its out it cant go back without yet more cost.

Hi just a quick update, removed dpf today and left cat intact.
Will put it back together tomorrow and it should get re mapped with egr and dpf delete through the week. £180
Its one thing i wish i could do is re mapping but a bit scared to as i have never done it? Anyone here do it? is it worth getting into?

Hi Bradley,

I have been undertaking remapping and DPF deletion for a number of years. The only basic important pieces of advice I can provide are: use a reputable company with tried and tested files, use the correct genuine equipment and undertake the correct safety procedures. The people I use offer full training and full telephone support and advice.

I have been to customers who have had poor experience with "cowboys" offering cheap prices which are only possible with cheap files and equipment.

I have been in the trade for 25yrs now and find remapping most rewarding both for financial and personal reasons. Tuning in the old days generally meant improving the performance of a vehicle because it had got "out of tune" and rectification brought a smile to a customers face. This does not happen nowadays and generally poor performance meant a component failure and lots of money to put it right. Remapping is taking a perfectly good car and transforming it into something better and the smile on a customers face as I said earlier is most rewarding. DPF deletion saves the customer a lot of money.....which also brings a smile to his face.

In summary, I have found it easy, a good money earner and brings me much job satisfaction.

Regards

Pete M

Thanks Pete I have just got in from drill its a bit late now,
However i will update you on my car.
Had the egr and dpf delete done last week. £180

I put a blanking plate on egr and removed the dpf myself, however 30 miles and 2 days later after remap eml and limp mode returned..??
I read codes with launch to find 7 codes, glow plug, egr flow excessive, egr no flow, fuel cap,
i cant remember all of them but at least 4 were egr related.
I rang our tech i paid to do it and he said clear them as when he remappes a car he doesnt clear what is already there its probably one of the other codes causing the light. I replied i have never seen a glow plug open circuit cause a eml and limp home issue? He then asked me to return the car to him if it came on again and he will look at it free of charge. EMl and limp came back on sunday so it went in this morning. I checked the codes but never cleared them before it went and there were 4 codes, egr flow excessive, egr insufficiant flow, and another egr related. plus glow plug open circuit.
He rang me later on to ask if i had fitted a blank in the egr, i replied yes and he told me thats the problem, He says if i remove the blank it will be the end of the problem..?? I replied with "the reason i had you re map it was to discard the egr from the syatem" he then said ""his peugeot top tech has plugged into it and says this is the problem i am doing other jobs and dont have time to think about your car at the moment, get it picked up and remove the plate""
I cant understand how the car will run with the egr pipe unblocked and an unreliable egr valve.

I dont understand it but maybe someone can explain it to me, thats why i have just posted this long winded essay,

opinions please
Kind regards Brad

Hello, I have done quiet a few of these, I specialize in French cars so get quiet a few from other garages after somebodies had all the profit out of it!!!Remove DPF and EGR delete usually creates more faults than it cures and then the remapping firm generally walks away from it with the " u did what u asked me, not my problem now" attitude!!!
The original issue i believe is down to the cap sensor. This has caused all additive(or most of it) to be injected into your fuel tank, this has caused DPF to start blocking prematurely, the vehicle has been trying to regenerate but cant due to glowplug failure which compounds the blocking of the DPF. The original misfire/egr fault I suspect to be caused by excess soot from failed regeneration
All a bit longwinded but hope this helps

Hi Mark,
I fully understand what you are saying, however i have had no problems with DPF, it still has a good level of fluid and the dpf system is still in good order. The Egr however wasnt as mucky as expected when i removed it but did appear seized or very sticky. I have checked the filter at the banjo on the turbo oil feed pipe and it is as clean as a bell so that all seems good.

The fuel cap sensor is working on live data and dpf tank has sufficiant fluid.
I believe he has changed the paramiters of the egr and not deleted it as i asked.

When i remove the blanking plate as the "puggy top tech says" will all be good or will i need a new egr valve??

Yes if i had known what i know now i would have got a new valve fitted it and it would all be done now.

However the car is for my wife and i, and i wanted it to be reliable. The car has done 80k miles and i was thinking the dpf will soon be needing attention and egr valve was £120 , remap £180 so the extra £60 would give me insurance in the future that egr would never fail and leave my wife stranded as she was when it played up last time and no dpf probs in the future.

All sounds good.

But now when i remove this egr blank and if it does run fine i can never be sure she wont be stuck with egr problems again as i am again relying on it not being jammed open.

Do you think this will work with a knackered egr valve?? I think im being fed a load of c##p by them. I asked if they can delete the egr and dpf and they said yes so i paid the cash ,now they are back tracking on their word.

Darren,

I know this is a 54 plate but if i was buying a new car what car is reliable??

They all have too much to go wrong now. I think reliability on all cars is poor now,
some maybe worse than others but all poor.

It seems i have been fleeced! My belief about removing egr blank is correct,, It failed on me yesterday stranded with no phone signal and a car that woudnt do a thousand revs without a big cloud of smoke and then stalling. Code: p0489 and p0409.
Had o get tools and replace blanking plate to get it home.

16/12/13 quick update. Rang them up today asked him what he is gonna do to sort it and he told me there is nothing wrong with it and hung up on me!!! looks like i spent £180 for nothing!

Hello Bradley,
I have just had a Citroen in with 9hz engine & several egr faults. There were several faults caused by others testing the system previously, which I had to put right first, then after checking and rechecking again, I was convinced it was an ecu fault, so got a donor ecu , which made no difference. There was a software update for this one that allowed the egr to initialise, where it wasn't before.
If you check dynamic data, is your egr valve copy signal matching the command signal?
I think your answer will be a software update, which is what I should have done to start with.
Ps I would insist on your money back from the remappers as they obviously don't understand what an egr delete means, the only problem is though that you will need to refit everything, if/when you get the ecu updated.
Regards, Anrrew
