bmw 320 d of the 2004 mass air flow sensor again the same error

hi all,I have a bmw in the workshop of the 2004 engine type 204d4 150 hp that sometimes the light comes on and the diagnosis of mi by air mass sensor,aiche change the sensor,after various checks,type egr, sleeves,butterfly collectors,pressure sensor,turbine, variable geometry,and catalyst,but nothing after a while siriaccende ,even after 2 or 3 days.air mass sensor value too high,in fact, if I look at the real parameters of the nominal value (what you would expect in the control unit)to a minimum and' 225mg while the actual measured from the sensor, and' da450 a480... hello in the meantime, and thanks in advance if you'll give me any straight

sorry I state that mounts a edc16 so no updates or coding to change mass air flow sensor,hi

you have the egr closed on this car??

I closed after you have changed the mass air flow sensor to the test ,I saw what was going on I still have it closed with a sheet round inserted on the tube of the valve, but if you noticed, I also gave error recirculation then I removed it.the egr is clean and functional,the block egr I did that with time,do you have any idea?

on these cars, there have been problems of sealing valves, and among the many errors and gave also to meter the air.

you say that it could be a mechanical problem then?I try to do a compression test in the morning,for safety,thanks in the meantime. however, the car has only 157000 km, and the customer has kept well,aside from the oil change every 30000 km,which I am not so agree,but....when I removed the intake manifolds I found them "clean"compared to many other cars

IF you are first blocked the egr with a time, and then you had the error, I would say to put gold and try... maybe the soft did not do well what he had to.

regulates air flow from the map , practically lower the sensitivity? maf until the air mass, which corresponds to the measured mass, however, I think l egr ? closed
post the map if you want

then I remember that ? can reset the learning maf
test

the egr I closed after it was turned back on after the replacement mass air flow sensor,and reset, I already tried after all the tests I did,the parameters of the maf I can see them with the ecm or do I have to seek you out drivers?I fear that loss of power even if the problem is more low rpm,when it arrives to 2000 data correspond almost completely,I placed the files

when I'm defect notice white smoke in the exhaust???( I do not mean to fap)

here are the files one gold and the other egr

I do not see white smoke, the fap does not have it,but if it does a little, maybe there I made the case in the morning to securely control,do you think that maybe burn evil ?or something else

out of driver, give us the data maf measured and objective, at a minimum , 1000 , 1500 , 2000 2500 ,

however, if you have closed the egr ? more than normal for the maf reads more air....
normally a 2.0 with the egr open you maf values between 280-300 mg with egr closed values rise of between 400 and 500 mg....

I give you the precise data tomorrow early in the morning,however, at a minimum 830 rpm, aim between 227 280 actual instead of between 430 to 485

here is idati

the nominal effective
1000 278 472 mg/strk

1500 251 467
2000 271 437
2500 407 636
3000 522 609

sorry it came out a little bad about the 4 digits are the speed of the first 3 and the nominal value of the other 3 the real value

you gi? that said...for the way of closing the egr your maf reads more....
if you try to re-open the egr the maf aligns itself more or less to the "nominal air"...
if not then you would rightly re-open the egr you can moddare in the ecu all the objective map maf:lambda,lim fumes on the basis of maf,sensor linearization,corrections,etc......
or even you could also just disable the P-code in the object so that the box most of the discover.....
sure that for? in both cases, this work is a p? the long and complex enough....

I already throw-ori but nothing and also because the problem I had before it is closed ,I do not know the things' the p-code to me you could say please,thank you in the meantime

you have put back the original file , with the plug on the Egr ?

no I removed it

the maf ? original or ? chinese ? or do you have the egr stuck closed

mass air flow sensor bosch ori taken from me usually atoricambista with the last 2 numbers changed because he said the warehouseman who have replaced the box and' ori
the numbers above the old sono0928400504 instead of a new one, and' 0928400529... for the egr in fact it was a bit hard, pushing it with a screwdriver but it runs and doesn't crash,I don't know more what to do.unfortunately, to map it out the driver or change the switch control are not enough expert,with ecusafe when working on the file on the dtc what does it do?cancellation errors or takes away from the map control?' cause if you can I would try also quello.su the five tools of diagnosis,oscilloscope,and assistance rapidoo and a few friends in the bmw nothing to do,I continue to work for nothing

The problem ? only one...
when you report the fault ? everything ok ? no loss of power ?
ecusafe delete a download of dtc ,
in the diagram do not see anything , but ... if the problem sends you in the recovery , we go without a mill on

when he went to the recoveri with the old mass air flow sensor the car there was not now pulls with new mass air flow sensor but the light comes on

dtc off ? crap but it works ...

port 00 0E4EF6 - 0E4F50 you can not see the file

non pu? download....

According to me and other than the conversion between the read value and the electrical value communicated to the ecu a friend of mine has the exact same problem

ok I feel today as soon as I have a moment I have to do it with ecusafe manual or in hexadecimal with the ecm?was for the commitment

Do with ecuservice...only dtc

hello,for now it's all up to marvel ,I can give you more info tomorrow early,I have also put ori the egr, in fact, the values are normal but without your solution would never be resolved....wait for you tomorrow.but even if it were fixed I don't understand why,maybe autoadattativita'?or the motor that controls the variable geometry ,which, as a replacement will damage the turbine...***** o guys thank you so much and if you need I am here,see you tomorrow I have to hand it over for now in the evening villa I have time to try it.

nothing to do after about 50 miles and again the same error

according to me, they have put in above a mass air flow sensor on another machine and changed the map of converting the intake air/electric signal, and is now putting the original does not work

hello jovandj,however, the ecm knows how to map ori,even if, to tell the truth on a scodifica of an edc 15 ,once the check sum is not me that I was correct ,and she said that everything was fine,caricavo the map,but the car would not start,I had to do the check with donatello's an old program of 4 years, econ one, and it started without problems,it does not recognize certain changes outside driver....I have to search for a map ori and then put them in comparison,if anyone has any advice..thanks

the area moddata in the map does not correspond to the dtc true according to me
which as you can see, continue to work

you may aitarmi?

post the error code

the code is 3ff0 and once together and come out 3ff1 ,are codes bmw tomorrow I try with the other diagnoses if you want the type codes ami poxxx etc I am attaching a pdf with the code bmw,thanks hello

here are the dtc bmw original

sebastian..but you're mother tongue is Russian??? but...that...what seats....look at that, you have to post the normal P codes not ? you need to try to send sputnik into orbit around the moon....
when you plug in the diagnosis, what are the dtc P-code that gives you the car?? es P0191,P0157.etc.....

you know but I get the codes so the brienbee now I try with another tool and then tell you

the error is p3263 signal mass air wrong

According to this error I can tell you that it could be either the intake manifold very clogged or the motor fails to download good
