Problem smokiness Peugeot 308 1,6 hdi no fap

[ducati83]

Hello guys I wonder if anyone has experiences about the fumosit? of this car, all original about 120k km:is in the ignition and walking slowly emits continuously a bit of black smoke at the exhaust and then not tell you when you push the pedal in an overtaking or speeding up...looks like a car mapped, but not the ? and also a bit the car seems a little off....according to you?
I immediately thought the egr was open maybe....even if the diagnosis there are no errors....only once has the error relative to the egr valve but then nothing more.
thanks to all

[legendaryslave]

some of the turbo coupling that vents or turbine that is not working as it should also attributable to the egr

I legendaryslave, controlled well the tubes depression and the various solenoid valves, a pressure gauge midivac, check if the vastgate of the turbo compressor, it works well..

[enzopezzano]

usually on those breaks, the sleeve intercooler. check them out.

[ducati83]

perfect I control sleeves and diagnosis I try to see if the turbo pressure ? adjust....but how about if you try to disable the egr as a first try?

[enzopezzano]

if you have problems with the egr you should have engine light on, error message on the display, with the caption "anomaly antiinquinamento". check sleeves, turbine, and if we want to be sure from a subsidiary to the values of the MAF. Hello.

[legendaryslave]

Closing the egr it takes away a problem the council to close it with sheet metal

[ducati83]

ok make? these controls and I keep you updated....
in any case I would put the plate, thanks for the advice.

sleeves intercooler would check them in the first place but also vents the exhaust type in the manifolds close to the prisoners, which sometimes break...

[ducati83]

controller? also those...

[enzopezzano]

Break down the drains???? 3 years in the Peugeot and has never existed on this issue.

[ducati83]

perhaps you were referring to the fact that the problem may be due to the fact that the drain could be leaking.....not that the peugeot break categorically...

exact ducati 83, enzo I was not referring to the specific type of case failures peugeot but it was only a board of
the controls that I would have done...

[crteam]

on this car there is a sw update of the controller that solves this problem.made all the controls if and tt ok to go to peugeot and made to update the ecu.also check the memory fault

[ducati83]

for now, nothing broken.....I only see a strange behavior in the diagnosis of the egr.....sometimes I accelerate, and it opens sometimes it is closed....then at least opens and closes.....
hmmmm is it possible that this is the only face-to smoke even at idle the car?

[crteam]

Not that you got dirty diesel?

[ducati83]

well you might but it does a bit, and then I don't see how it could go crazy in this way, the egr with diesel dirt....is the desk from open to closed not only by a few degrees...***** and if it did check every so often and the car always smokes....
now I work to delete the egr and see....I just hope not to have problems coding the injectors with the cock...

[fuorigiri12000]

In diagnosis, you d? errors in particular.

[ducati83]

no error ? this is the thing that is very strange...only a couple of times the error for the egr...but then what ? went away by itself...

[fabio1207]

I solved it with a cable to the spring on the valve of the turbine (the wastegate) no defect in the diagnosis of the valve with the vacuum gauge was working fine but the tube aspired air why? it was a bit dilated mass, the band ,tested ,delivered, and still today goes well ,see for yourself

[max boost]

To stay with the doubt dell egr escludila...possibly from the map, or physically with a plate, so to evaluate the effects of egr on your problem fumosit?...I hope I made it clear...

[ducati83]

hmm, in fact,....why? I saw that the tube ? only innnestato.....prover? also tomorrow, together with the elimination of the egr.

[fabio1207]

No go quiet, why? I, too, was a little bit reluctant, I didn't think I could lose so much (only) in that way, but then I changed my mind*****s, regarding the egr valve, I don't know of everything, but I do on the plate that I put in place of the gasket, a small hole of 3 mm*****o,before it is put in motion,pull the tube,clean the inlet on the pipe (the one on the wastegate) then put in motion the car with the tube disconnected, and after the attacks and see if he moves the rod if he pulls put the sash and try it.Hello let me know .

S? have any news of how v? the car? If ? been fixed and what was it ?

[ducati83]

sorry for the absence but I have had to do with the influence and problems to the internet line....
then update:the car has not had any broken pipe or leaking....I checked everything....I closed the egr and it seems to be improved a lot all....both the fumosit? at idle, the ignition of the car when cold....hot no smoke at startup...it's just that there remains considerable smoke in acceleration during a tug, or in overtaking and travelling to 160-170 smoke comes out of....now I would like to understand if some of the air sensor like the MAF may have a problem....c'? a way to manage it from the map?

[ducati83]

small update:after the improvement with the closing of the egr and the various pipes tightened to duty as advised me fabio,I also replaced the MAF and the smoke to a minimum ? gone totally...only that remains very evident in the acceleration...or shooting for 4 or 5 gear....

[max boost]

very likely the egr ti ti has soiled the inlet manifolds

[fabio1207]

try to do some km in constant acceleration (without pulling) may have contaminated the drain.

it would be important, as it says in max to be able to dismantle and clean the ducts

[ducati83]

prover? to clean them, but I don't think that is the problem....gives me the impression that it is a cattavi gestioe of some value, ch does send more fuel that is needed....

[sergiot]

you have to look for a significant loss of air in the stretch from the discharge side of the turbo to the intake valves.
the difficult lies in the fact that this loss occurs mainly when the turbo pushes hard.
browse all of the hoses, the intercooler, but not only the clamps, as perhaps you have already? fact, the tubes whole, the intercoole that you might lose.

[ducati83]

it is, in fact, tomorrow night I'm back to the car and I really wanted to inspect the intercooler....unmount and put it in the pressure with the water pervedere if I find leaks....

[fabio1207]

Ecu ? the original? If you like said sergiot pu? be for? you should feel a strong breath

[ducati83]

it is the original...only the egr excluded.

[sergiot]

Ecu ? the original? If you like said sergiot pu? be for? you should feel a strong breath

? difficult to hear why? the breath develops more? high speed? of the car

[fabio1207]

? difficult to hear why? the breath develops more? high speed? of the car
? true but it should also be heard in the speed? pi? low with the engine more? the top of the rpm of that? pulling more? the second and third gear.

[ducati83]

guys Thursday I continue to remove and will I know? say....

[sergiot]

? true but it should also be heard in the speed? pi? low with the engine more? the top of the rpm of that? pulling more? the second and third gear.

if ? true spouting the intercooler or pipes, when you drive, the vent is open to almost 2 metres away.
to hear what you say, you have to be in 2 with 1 out and listens.
however, I suggest that fabio of control in a hurry why? these situations are then harmful for the health of the turbine.
