guys I have a lancia y 1.3 75hp that does not push in diagnosis no error but checking the parameters I find
quantity of the intake air 200
quantity required 500
pressure collectors around 900mbr very little for this engine, the egr works at least watching the parameters at the minimum and about 30% by accelerating then goes to 0% it might depend on collectors?
does not read the right amount of air, now, or not read the system because of failure or because it does not enter air into the engine...
Hello the car how many miles .when you accelerate you hear a few whistle-type turbo tube broken?the values of the mass air flow sensor that to found are with the egr valve open? Or closed? If you do the test in third gear starting from 1000giri, and then mash the accelerator pedal to the floor the turbo pressure that value is?
I've not done this test now, will update us whistles no
controllado I have still noticed :
engine rpm 2500
position objective the egr 0%
position egr 18%
this could be the cause ?
I know that if the egr remains open the pressure in the collector decreases, but I don't know how does the mass air flow sensor in these cases, if it aspires less or more because if you were to reduce the amount of air the cause and your egr isn't it ?
if it remains on the mass air flow sensor reads less air, smontala and you can be sure.
if you have BOTH the MAF is MAP low have to be the turbo that is wrong or leaking air somewhere between the turbo and manifold intake..Quote:

To force the turbo in that sense it may also be caused by the egr open right?
check that the drains are not clogged
hello, I have a gp 1.3 90 with about your same problem. While I pulled the 5a at a certain point, he stopped pulling. After various saints I have encountered in the order: operation wg (on my everything is ok), log of various parameters on the esm and check the sleeves. In the end I disconnected the sleeve of the ic, and I noticed that accelerating the turbine is not blowing. Turbine ko. See, first, if the wg works on yours, then look for any leaks in the hoses, and finally try to disassemble the turbine according to meQuote:

guys a small update on the wg on the turbine does not work, or rather the diaphragm holds the vacuum given with the hand pump, but the stick does not walk
Probably due to the geometry locked

first thing's first, I correct what I said this type of wg will not work with the vacuum but with the pressure of the turbo itself, but it is always locked now I try with a little wd-40 will update

I unlocked the wg but nothing pressure turbocharger remains firm on 900 mbar on the nut intake there is a tube that should open the wg, but does not exit its air of not even picking up

I imagined it was pressure and not vacuum, the last one I can only find 90 or 95 hp that have variable geometry...Quote:

The wg is the pressure, in fact, has the tube running from the group, the cold of the turbo and goes to the wg which opens when it reaches that pressure, but does not exit the air from the tube I if l kill
I disassembled the turbine and the coperchiello from the exhaust side is commanded by wg remains slightly open, so I guess it is here the defect you say?

and it also moves by blowing with the air in the wg rod walks "now", while before it was blocked, however, when the wg and the whole closed and then without the pressure of the air that opens the hood which is in the part of the turbine exhaust remains for me to slightly open
Regulates the wg to keep it closed at rest,often these turbines in case of frontal impact, the dell drive to rotate the casing, the cold side on which is attached to the wg moving so the adjustment...or perhaps if it was replaced, it was installed wrong. Calibrala and see that the car will be fine
fixed with the turbine new was ruined, and there remained the wg within a thousand thanks to the next
