Peugeot 307 1.6 Hdi showing "Sys Antipollution Defaillant" and Black smoke when drive

Hi members ..Mine is Peugeot 307 1.6 Hdi diesel. Check engine symbol is coming and on dashboard display "Sys Antipollution Defaillant" is showing up. Loads of black smoke while driving the car.
I have no idea on any one these as this is my first diesel car.
I took it to a mechanic, he diagnosed the car and said need to replace injector seals, glowplugs and Fuel filler flap sensor. But he is not sure with the smoke. He kept me waiting for the parts as he ordered from dealer and nothing showed up. I myself done some online research using this and other forums I bought the parts.

Now I have got all the parts. but there is no apointments with him soon near.
Can we replace the parts by Ourself with out visiting a mechanic to save time and money.

And I have seen in some posts talking about "Peugeot Planet 2" something like software. Whats the use of it and what all we need the tools to operate that.

Thanks in Advance.

Would have been better to buy the pp2k first before taking his words as unless they know these cars intimately most garages, and that includes so called Peugeot main dealers, have not got a clue. The injectors are not cheap for a start and unless you are mechanically minded it could lead to disaster but hey if you are up for it give it a go.

Thanks Madbadandold. He said until he fix those injector seals and fuel filler flap sensor he cant go further ..he charged me £45 only for just to diagnose.
So I thought its not something chepaer to go to another garage and get it checked. Where will the PP2K is available and how much it could cost to purchase that.

And me too from stoke mate :)

Whereabouts in Stoke are you? PM me if you don't want to advertise your whereabouts to all and sundry. There is a helpful diesel specialist, Lucas in Burslem ,that can give your fuel system a thorough check over before you go ahead and start throwing money after it and I have pp2k if you need to use it.

Does the car feel underpowered? Stuck open egr valve can cause black smoke, too much fuel or not enough air could also be a problem.

Hi Stevoxsi. Car is reaching more that 3000 rpm,although i have no idea about EGR valve , i feel everything fine but some time it feels like underpowered until it reaches certain speed like 50 mph . The visual Problems is some oil accumulated near injectors and one of the injector is making "Hish" sound when the engine is running.

So you don't know anything about topping up the fluid that the car needs to regenerate to burn the crap out of the Cat? What can happen is that every time you open the flap it triggers to squirt a dose of the fluid into the cat. So really the only time you should open the flap is when the tank is really low on fuel as each squirt is equivalent to a tank full of fuel. So it just might be a blocked cat. The members on the forum suggest removing the cat and washing it out with a pressure washer.
How did the garage come to the conclusion of his suspects. Did he use a fault code reader?

Soory for the late post. Yesterday noon I have met this person MADBADANDOLD from this forum in person. Very Enthusiastic and dynamic. He is very generous and tried to check with his Peugeot Planet 2000 setup but unfortunately its not supporting my car and don't know the reason:confused:. With a little time in hand we both checked the Engine bay and tried to clean up as we can see some Oil accumulated at the injectors and he noticed the sound from the injector but havent came to a conclusion yet, as we took our time with the PP2000 check engine which is unsuccessful. Since I have got the parts I'm interested in taking some risk in replacing them. He advised me to go through the Car repair and service manual for Peugeot 307 as those parts should be replaced with high care and our safety and the great thing is he is offering his help in replacing them soon or later. I have started reading posts regarding this and watching the particular injector and glowplugs videos to have knowledge on them. Will Update the the progress once I sort these out in first place:nod:.
Thank you :thankx: MadbadandolD for your Valuable Time and Advise.:thumb:

Reading through past posts and one mentioned that they found the injector retaining bolt loose and tightened it and the fuel smell went away. A cautionary remark stated that you have to be careful not to overtighten the bolts as it can crack the head but it is worth putting a spanner on the bolts just to check. Ultimately the reason for the bolt to slacken will have to be resolved be it washer failure or cracked head but for the short term I would check tighten them with a torque wrench. According to the Haynes the torque figure is 5lbft!

So, yesterday, we check tightened the injector retaining bolts and indeed found No 2 loose. Retorqued it to the prescribed figure but it made no difference to the leak, still hissing. So we will have to remove the injector and check the copper seal. How can they fail? Do they break up or what? We also removed the turbo outlet pipe to check for oil and sure enough the pipe is wet.

So yesterday we had a go at removing the injector and even with the nuts removed from the mounting flange and with the engine running we could not get it out. The fact that they are held in with nuts and studs instead of bolts does not help as the twisting technique cannot be used to try and loosen them. So a puller is a must, on this one anyway. We managed to replace the fuel flap sensor though. But as he drove away his clutch failed. It turned out to be the circlip had come out of the slave cylinder pipe but luckily it was still attached so it was "adjusted" and refitted! Happy days eh!

Injector leaking at the seal wont really make much difference to the running it will affect it a little but not much.

Black smoke means there is not enough airflow generally or its pumping too much fuel in lack of airflow is much more likely probably because the turbo is not working properly this in turn gives you the antipollution warning.

I would look at the turbo make sure its control system is working properly IE good vacuum and if a variable one the vanes are free

That is weird as even the AA man said the seal would cause the black smoke as well as the two garages he has been to. Myself I have had my doubts as for one the car has not been looked after and he was told the fuel cap sensor was U/s. So saying he has been doing short refuelling and no long runs so I am more inclined to go down that route. Also the outlet from the oil remover breather unit on top of the head which looks like a rocker cover is oily when running and I am sure the egr system will be gunged up from the looks of it. But he wants the injector fixing so so be it.

I'm with reliable on this one... visible black smoke is mostly caused by overfuelling due to boost supplied not being what the system is asking/programming for. A slightly leaky injector seal is not going to result in loads of black smoke.

Check what boost the system is making when under full acceleration. Normally should be in the 15psi range. If way below this, check for leaks in the turbo piping and check vacuum/boost valve. If this checks out ok, you need to look at the turbo.

I have just repaired one where the variable vane system was sticking partially open so was only making 8psi max and loads of smoke. De-coking the vanes freed it up and back to full boost now.

Get the injector out and clean it fit a fresh seal by all means as it needs done anyway but regardless what AA or garages tell you it will not fix the smoke turbo gummed up or something similar is far more likely.

Get some carb/brake cleaner and run the engine with clamp bolts loose NOT removed and once the carb cleaner and compression work their magic you will get injector out

We tried WD40 and some say even Coke! That used to work miracles when the "old" formula was used. I doubt it does anything now. It was not called rot gut for nothing! We used to use it to clean the aircraft windows after the flight crew had used the rain repellant in flight. The recommended glass cleaner did not touch it but a small can of coke did the job no bother!

Here is a video of before....

As stated above the injectors can be a right royal pain in the Glutus Maximus especially if you have a fuel leak and it's set like tar :mad:

My Method......

1) Make sure the car is hot i.e. cooling fan comes on.
2) Loosen clamp bolts
3) I used a lot of Electrical Cleaning fluid to break down the tar (diesel fuel) but please be careful as it is combustible
4) Get on old screw driver and scrape away as much as possible
5) Place a piece of wood across the front of the injectors and use a strong screw driver (I used a pry bar) placed under the fuel inlet nozzle of the injector and apply pressure. Don't try to force it out, firm constant pressure is all that's needed until you clear the studs
6) Once clear of the studs you can twist it to aid removal (Wear gloves as the injector will be warm/hot)
7) Once removed the tar was spread all down the length of the injector/chamber. Again I used contact cleaner to remove the majority of the tar in the chamber which then exposed the copper washer.

Ideally you don't want all the crap to go into the cylinder and using contact cleaner meant the majority would evaporate. sure you'll get some crap in the cylinder but it did start out as diesel in the first place :nod:

8) I then plugged the washer with the cut off end of a tube of mastic nozzle. I then went to work on cleaning the chamber.
9) The washers were well and truly stuck in the chamber so using the nozzle I had made I placed a sturdy screwdriver into the nozzle and tapped it into the washer.
10) I then doused the chamber with contact cleaner and after a bit of wriggling about I managed to get it out.
11) Clean injector in the same way, fit new seal kit and replace.
12) I replaced all four sets on my injectors (only one was leaking) the other three were a lot easier than the first one

....and after injector removal/clean/new seal kit.....
