GOLF IV 1.9TDI - Sudden Loss of Turbo Power, No VAG Connection, ELM327 Shows No Errors

Good morning, I do not know where to write for help.
I'm not a complete layman but cars are not my leading horse ...

Shortly 2-3 days ago the car was driving normally.
And suddenly it turned out that there is no power ... as it accelerates slowly, it somehow goes ...
But how it "depts" is max 3000 revolutions and it goes "hard" and loud.

A typical symptom of damage associated with recharging.
It fires without any problems
the temperature of 90 degrees even when the weather is cold (of course you have to drive a little)

The whole problem is that I have ELM327 after the computer has been propped up and read, there is not even one mistake ...
As I come in to show the status of sensors (graphs) it shows ....

But there are no errors. However, VAG can not establish a connection.
and now the question is how to diagnose what could have happened.

It does not smoke, but it does not feel like a turbine.

the veins I saw are ok (I exchanged all about 8 months ago)

I do not hide my impression that the problem is a program that somehow does not read the error codes from the computer of the car.

maybe this elm327 is sucking?

Or can there be a situation that the car is not working properly and there are no errors?

You have probably dropped a flow meter. Release and see if it will improve.
If that does not help, then you have to do the VAG logo.

The easiest way would be to connect the diagnostic device, read the errors (if any) and see the parameters live, but if you claim that you do not feel the turbine, take someone to gas you and tighten the rubber hose on the intake and you will feel if the turbine blows. Of course, this does not mean anything but you will know. Something on the counter is shining or nothing?

All the trouble that I have ELM327

In fact, it's a big problem. Take out the trash. Only VAG here. Otherwise, it is fortune-telling from tea leaves. From the clogged fuel filter, through the fuel itself, to the turbine ending. You do not want to fix everything in turn?

Connect the iron ... we'll probably find out more. See if the bar is pulled up after the boot, the actuator whole, the geometry does not stop?

Back to the topic...
I connected viakena. He joined without a problem ...
But the p1357 trigger has nothing else ... Vag describes as a fault in the temperature sensor.
No errors appear. And the engine is silted.
I'll make logs tomorrow. The manual closing of the valve on the intake immediately extinguishes the engine, so it does not tear the pipe on the intake.
I wonder if it's not the fault of fuel because I recently refueled for the orlen ... And right after that these troubles ...
Tomorrow I will try to look at the movements of the pear from the turbo. Once I was in trouble with the hole ...

I completely disconnected the flow of the ps ... The same or maybe even better ... I connected the second flow, it still licks the same.

Oh sweet ...
First of all, what engine? Deisli was probably 5 out of three, in three different genres - with VNT, VTG, VP and PD - which do you have?

For what? Two things are interesting for now - the boost pressure and the MAF indication at idle.

Good day.
I took a screenshot and added as an attachment.

MAF (specified) - 290.0
MAF (measured) - 290
RPM - 966
EGR Duty CYCLE 84,5%



Regarding air flow:
on a cold engine because I did not get warm by driving to work.
2988RPM, 1897 plotted, measured 1009,
the second attached file



reading the codes gave such a cass:
17664 - Engine Coolant Temp Sensor (G62): Open or Short to Plus
P1256 - 35-10 - - - Intermittent
17964 - Shareware Version. To Decode all DTCs
P1556 - 35-00 - Please Register / Activate

If you have flooded an ordinary ON, check / replace the fuel filter.

P1556 - does not load a turbine. EGR inlet / open hole / N75 valve defective. We'll find out in the end what this engine is?

HE VERVA or what he is called at the station in CK, do not go for those "ordinary" in the winter only, that I usually buy BP, and hit orlen ...

data from VAG and propos of the car data:
Component and / or Version: 1.9l EDC 0000SG 3349
Software Coding: 00002
Work Shop Code: WSC 01266
Additional Info: WVWZZZ1JZ3W .....

However, go to some workshop because we will not get along.

I have no way to check the engine type at the moment.
I give VIN: WVWZZZ1JZ3W57 ....
Normal pump (no injectors)
90km
But the VIn itself is not likely to give information about the engine.
There are no unstets of stickers in the trunk. I will find a vehicle card at home that I will give the type of engine to ALH, but I will check.

unfortunately, I do not have access to the garage to get started and have free access because I'm coming back from work too late.
The last time the snakes were spreading, but I mentioned I was immortal ....
The turbine is always working, because it must be faded ... but I do not know if it is possible without any effects ...

I will undress during the weekend.
because I suspect a pear serpent or N75, although I substituted 2gi (I used to buy one) and nothing changed it.

On the timing cover there is a sticker with the engine code on it.

I had so that it accelerated to 80 and it was poor and above 80km / h he could not practically go higher. There was a pear to clean (turbine valve), after cleaning it took on the old power.

for sure, there is a pear tuber to change. I managed to take it off and there is no such moment that it is underpressure ... how it pumps it all the time ...
or the pear is a hole ...
I will let you know how I can get to it to replace the node.

I have a hard pear inside, as I say, look there for a reason.

Welcome again. As the problem was solved successfully. I think about the subject as closed.
Two things were damaged.
A) the new pear cord was leaky. Under the cotton warp we could not see it.
B) the n75 valve was damaged. He let it in all directions. I fixed the valve.

Works ok
Thank you for your willingness to help.
