Experiencing Turbocharger Overcharge and Rotor Blade Error in Ford S-MAX 2.0 TDCI 140HP 2007

I have a problem with the Ford S-MAX 2.0 TDCI 140HP car. After buying the car (about 2 months ago) it turned out that the turbine did not work (charging 1.1 BAR). The inoperative turbine was replaced with 'after regeneration' and it was fine for several days (charging 2.49 BAR). After about a week, the turbine began to overcharge, which was felt because the valve in the system was relieving pressure and driving at high speed was not smooth (continuous reloading and relieving pressure). An error has occurred in the computer: the turbocharger rotor blade programming limit limit exceeded.

I sent the turbine for service under warranty. The same copy was sent back to me, like the rotor was a problem, but it's ok and can be assembled. After installing on a cold engine it was ok, but when the car was warm the reload effect returned.

After about 1-2 weeks of driving the car caught a light 'mule', but the reloading effect partially ceased.

Currently the car charges 2.32 BAR and only when the gas pedal is released and the turbine is added again it charges above 2.49 and reloads the system again and the effect is as before.

The question now is whether to go to the next turbine or maybe it is something other than a turbine.

The MAP (pressure in the system) sensor was replaced, the DPF was burned out - I don't know what may be the reason for this behavior of the car, and I care about driving.

Turbine to be readjusted.

Turbine replaced with used. Works fine. Thank you.

Usually returns wrongly positioned, sometimes you also need to replace the pear.

If the regenerated turbine is under warranty, what are the chances of return or exchange? As I know life, the seller will say that this is a mechanical fault and is not covered by the warranty. How to approach this topic?

They also provide a guarantee for a kilometer limit or some period of time. There, the geometry had to be not thoroughly cleaned or set, maybe they have a weaker turbine pressure to regulate, and this is done with overloading. Advertise.
