Ford Focus MK2 2.0 TDCI: Experiences Jerks at 2k RPM, Error P2566 - Suspected Turbo Sensor Issue

Focus 2.0 TDCI HDI DW10 without DPF 136km.

When accelerating calmly it jerks around 2tys RPM. Sometimes it throws an error P2566. During dynamic driving is all ok, has power, etc.

Vacuum lines ok, pear on turbo tight, steering wheel does not jam - mechanically all hardware seems ok.

My suspicion - turbo copy sensor or control solenoid valve from actuator.

.

Decreases associated with the opening of egr.

The beam and the sensor itself to check.
Quite a typical fault.

But what caused?

EGR Delphi has 5,000 km - it seems ok - it doesn't jam, it runs smoothly.

No P2566 to check

Which sensor?

P2566 OBD-II Trouble Code: Turbocharger Boost Control Position Sensor Circuit Intermittent

I checked the sensor on an oscilloscope in Forscan - it seemed to show a graph, but in the range of 0-0.01.




Can I check it somehow? Voltage in the plug?

Return to topic - copy sensor replaced with a new one (the old one was actually damaged - no resistance).
No errors now. I did a driver reset.

Unfortunately, it still stops (it is clearly better, but you still feel it) and I have the impression that the engine is not full power.

I have checked yet - the turbo control works properly, corrections on injections close to 1, so it's not that, the throttle in the manifold doesn't get stuck (I don't know if the valve controlling it is working). The engine runs evenly, fires perfectly, does not kick.

What else can I check?
Added after 14 [hours] 38 [minutes]:
Today I have disconnected the EGR plug and everything works perfectly!

Anyone have any idea?

Hello .
I have the same problem in my 2.0 tdci focus, I am thinking about cleaning the throttle and replacing the EGR together with cleaning the metal tube, it all started with the fact that the turbine began to shed oil now is new.
The engine over 2k RPM seems to start and stop the turbo RPM.
You managed to repair the car, if so, which was the cause of the fault
