Seat Leon 1.9 TDI 90 - Vacuum Loss, Power Issues: Replaced Valves, N75 Valve, Hose Checks

Hello, the lack of power problem.
I have already replaced the valves and still no power. However, I checked that the barbell from the pear and the barbell from the extinguishing flap did not move during firing. In comp. Shows undercharging, TC fault valve.
I have no idea what to do next. Lubricate the N75 valve, I replaced the hoses.

Vac pump OK? the brake is ok? If it does not suck, it is easy to find the fault. Tubing, tube and mouth.

What brake?
From the n75 valve, I also do not feel anything continuous.
How to check the vac pump? Detach the hose?

When the vacum pump does not work, the brake servo does not work, so the brakes are very weak.
Do not look at the vacuum behind the N75, just look at the vacuum before.
You have a description on it. There should be VAC written there and there should be a vacuum on this hose after firing.
You can check it with a vacuum gauge or as an amateur, using language.

The vac pump is working. The hose to the valve was slightly clogged, after removing the muck, the valve is pulling but the problem is still there. Should there be a vacuum in all these hoses? And can they be checked in the same way? In the attachment there is a photo of some element to which the vacuum tube goes, but the end of "summer" is loose. From this [Xxxx] the hose goes further to the extinguishing flap bar. That way, maybe pinch the pressure? What is this




I deleted the obscene. [T5]

There should be a vacuum in the hose that supplies the valve, be it a turbine valve, EGR valve or a damping flap. The engine controller decides whether there is negative pressure at the output.
If you had muck in the hose, maybe it's in the valve.
The pear may have holes in it.
This valve in the photo is rather a valve from the extinguishing flap.
From the turbine and EGR, it should have a third hose that should go to the air filter, but nothing will happen if it is not connected.
It would be nice to do a dynamic log 11 and 11BS where you can see if the bar is moving and then you can create a negative pressure.
You can also give a negative pressure directly on the pear without bypassing the valve and then the pear should move the barbell, and if it does not, it has a hole in it or too little negative pressure.

Hello.
Today I did a "pear" test, the pear stuck directly into the vacuum does not move.
And additionally I made dynamic logs;
Groups 003, 008, 011: http://vaglog.pl/log-011_003_008_C12qb.html

If there was negative pressure in this conduit and the bar does not move, then: a blocked conduit, a hole in the bulb, a blocked turbine bar.
Try to move the barbell by hand.
See if the tubing is patent and if the coo is leaky, you can check it with a larger syringe.
