Problem IVECO STRALIS

[usardaun]

Hi guys, the experts of the truck, I have a problem on an iveco stralis 480, every now and then has loss of power!

[robby51039]

hello you have a diagnosis? what do you say?

[usardaun]

no, I have not yet made it! when not to ? as if the throttle responds late!

[robby51039]

so it is not easy to answer in kind might be vgt valve and sensor vgt but first make a diagnosis! if I can I'll help you gladly!!

[usardaun]

you say the valve that controls the turbine, which is close to the radiator!!

[usardaun]

you that diagnosis normally use on the truck?

[robby51039]

then lavalvola vgt is the one in front of the engine that you saw inside there is a cursor that sometimes with the hot block to try smontala and carefully try to lubricate

[robby51039]

diagnosis usually texa or autocom however, at times I'm going to a friend iveco and do with it.
oh, I forgot, you can do a test engine or test operation, always with a diagnosis

[usardaun]

I disassembled and lubricated!

[usardaun]

I bought myself autocom cables for the truck dave, you've got them?

[robby51039]

as l have found it ? it was hard, or flowed freely? oh, I forgot, you turn on the eoc when you restrict?

[usardaun]

no, flowed freely! will not turn on no light when it's the default!

[robby51039]

ok try to check the whole circuit of the low-pressure fuel including the decanter sometimes you find obstructions, then let me know

[usardaun]

ok, you tell me where you got the cables for trucks for the autocom?

[robby51039]

I'm sorry I bought them in china, I tried them work if the admin allows me I'll give you the link pin to make the diagnosis obd iveco 30

[usardaun]

ok, thank you!

[msport (exil77grande)]

I bought myself autocom cables for the truck dave, you've got them?

as I have recommended it to someone I can't remember who we also can provide the cables to the truck but do not go very well and I would therefore advise against the purchase.

[msport (exil77grande)]

I'm sorry I bought them in china, I tried them work if the admin allows me I'll give you the link pin to make the diagnosis obd iveco 30

mail the pin out.

[sisco]

I don't know the iveco? once ? happened to me a vehicle that could not, in the pi? it also lit the lamp for the engine , from the diagnosis, I remember that was related to the turbo pressure,asked a friend who works at iveco, I did check the air supply of the vgt before and after the filter ,clean and lubricate the actuator above the turbine to control the movement of the lever of the variable geometry but everything was ok in the end it was a broken intercooler,try to make a control by putting it under pressure, hello. I forgot, I also did the test turbo with texa and gave me all ok

[neo]

Hi ,happened to me and the same problem and it was the variable geometry crashed .IN the diagnosis came erore that spoke clear

[robby51039]

iveco 30 pin ground pin 27 +24-pin 2 k-line
eobd-pin 5-ground pin 16 +24 pin 7 line
I hope it is of help

[robby51039]

for sisco if the defect was itercooler would not sporadic loss of power, but always! then you would notice excessive smoke; hence, with a considerable increase in fuel consumption then you lit the eoc here might be that when asked to power the circuit, the diesel fuel does not have enough flow

[usardaun]

the intercooler ? was replaced a few months ago!

[neo]

Check the variable geometry

[usardaun]

the turbine ? was replaced a year ago, and still is fine!

[sisco]

I think that robby 51039 he is right, it could really be something on the diesel supply, you should test the vehicle with pressure gauges connected to the power supply circuit and diagnosis connected

Remove the lag?leggiante of the tank and clean the duct, just in case you try keeping it off the hook, and that fish type 15/20 cm pi? at the top, then replace the filter decanter, that many times it clogs up, and you do not see, as well as the filter close to the engine, the one marked defender.
If after these tests, even goes there remains only the valve in front of the engine that runs the turbine, which for? in the event you tip, try with a replacement for the avoidance of doubt.

When the mountains ? should talk place a couple of shims between it and the base of the thermostat that sustains it, in order to avoid overheating and breakage before.

[usardaun]

expect blackwolf76, explain better! I remove the float, and I try keeping it raised 15-20 cm pi? high! why? you tell me to do this test? then, if the filter decanter ? the one that is next to the tank I have replaced it! what? the filter close to the engine as marked defender?

[blackwolf76]

expect blackwolf76, explain better! I remove the float, and I try keeping it raised 15-20 cm pi? high! why? you tell me to do this test? then, if the filter decanter ? the one that is next to the tank I have replaced it! what? the filter close to the engine as marked defender?

You do the test with the float lifted as many times on the bottom of the tank, it takes on the consistency of the material that clogs the hole of the suction pipe, lifting it of the little bit that I said to you, you should not be subject to any problem. Of course ? a test to do, certainly not a solution to the problem.

As far as the filters, the stralis has a different fuel filter, main, in addition to the decanter that already? have you replaced that ? mounted close to the engine as half-height, on the right of the vehicle, slightly larger in size than the decanter. There is access to the cabin lift.

If I had to solve in this way, and we still don't have it, mount a pre-filter of the transparent ones on the intake pipe that goes from the tank to the engine, you will see any impurities? lately they are present in large quantities? in the new gas oils with a percentage of biodiesel to be high.

[robby51039]

the best thing is to check the entire circuit of low pressure,that is, all the pipes and filters if you want to be precise mounts a pressure gauge in the gateway to the fuel in the head if I remember correctly, the pressure of esecizio is 5.5 bar +/-0'3.how many km has the means? he never did check the nozzles inettori?

you have only replaced the filter, or even support?some models that do not have the support modicicato are covered on the inside (they have a diaphragm valve)and not riecono to reach the correct pressure

[usardaun]

hello robby51039, I have sent you a private message!

anyway, replaced the filter, and not the support!

injectors replaced a year and a half ago, it has done 150,000 km!

hi all, a information, the vehicle in question, rips or vibrate if put under strain when these loss of power?
if ? so very probably ? a problem of poor supply of diesel, unfortunately it's not? tell you what must remain the press feed, but if you can go back to the data you council to carry out the measurement with the gauge in the road and the vehicle is under load, why? I ? already happened that stopped the pressures are right, but under stress, the pump could not maintain a sufficient flow rate
if the medium is not ripping test to check the sensor turbocharger, you can verify the correct operation only with a pressure gauge and a diagnostic tool at the same time and compare the values are always under stress (no.b. sometimes the sensors marked correctly, but in certain conditions of pressure and temperature sfalsano the measurement giving the wrong information to the controller, which accordingly adjusts the fuel injection and will not turn on no light why? the control unit is not allowed? verify the correct operation of the sensor, except in the case of a short or open circuit
hope that was helpful and let me know

[igor]

oh, I forgot, in the case of a low supply pressure, first check all the system following the prercorso of diesel fuel, starting from the float as a gi? recommended by other colleagues, and replace all of the filters including the air motor (which from personal experience can? give these issues the cio? poor yield periods) and if still the problem remains try to replace the pressure relief valve of the diesel and for the last, the pump

[usardaun]

hello igor, after replacing the two diesel filters we say that still I am defect cali occasional power!! then I took a look at the air filter, and I noticed that there were two clips that hold the cap on the filter! I opened the cap and I found a little water and the filter is soaked!! I placed the cap of the filter, changed the air filter, and it seems that half goes! pu? be that from the cap entered the water when it rained and dust, giving the sti loss of power at times?

[igor]

? likely
let's say that if the filter ? dirty pi? wet air can not pass and, therefore, the vehicle is not breathing
if the problem reoccurs check the sensor turbocharger and clean it with a rag moistened with thinner
speaking with Sisco at work today we remember that the overpressure valve diesel in the vehicle ? integrated in the pump and can not? be replaced (provide only the pump)
but if you tell me that only by replacing the air filter seems to work better then ruled out a power problem diesel fuel, if the vehicle smoked black ir? usual during these cali?
if you was almost certainly the filter, otherwise it could be the sensor, I repeat may
I hope this information was helpful and you have found the problem

[usardaun]

Yes, I confirm, when it was not smoked more? of the usually!

[igor]

ok then, problem solved :)

[sisco]

hello usardaun it seems that the solution to the problem of the iveco is taking a positive way,I remembered that once a scania was and was not when he felt like it we discovered that it was pulled off the pin that drives the throttle valve of the engine brake that is activated at random, maybe ? the first thing you looked at, but you never know, hello keep us informed

[usardaun]

ok, terr? informed, we hope we have solved it!

[robby51039]

I'm glad that you've solved sometimes we puzzle over problems absurd and lasoluzione it is a good maintenance I only hope that my tips have been of help

[usardaun]

Guys I confirm, the middle is fine, the problem was due to the cap of the air filter that opened and was getting water and dust!!!!

[yellow]

Hi to all, also to me, captain of the stralis, which have water in the cover which closes the filter and change it by making a hole in the center of 4mm in order to expel the water that you are going to form.
