Issue with the 640d performance

[Gorrillaas]

2012 BMW 640d Insufficient acceleration at low revolutions per minute (rpm), without any indication of a malfunctioning engine or warning light. The automobile is at stage 2 of its development or modification.
What is the possible explanation for it?
Malfunctioning codes Error code 292200: The boost pressure actuator (VNT) is experiencing a malfunction or low voltage in its position sensor.

27B900: The exhaust pressure before the turbine is not plausible due to a tiny discrepancy between the observed and estimated values.

It seems that the motor unit responsible for the tiny Variable Nozzle Turbo (VNT) has malfunctioned, resulting in a lack of boost from the small turbo. This will also result in the plausibility code for exhaust pressure, since the system anticipates a certain level of pressure. However, because the little turbo is not increasing the pressure as predicted, it falls outside the intended range.

[Gorrillaas]

Very well... However, what could it possibly be? There are others who claim that I am capable of altering the pressure converter.

[dontito]

I believe that using a pressure converter will not fix the issue, since the vnt (variable nozzle turbine) operates electronically rather than via vacuum. Your code is designed for a certain position, thus it assumes that it does not get any response from the motor unit.

[Gorrillaas]

Indeed, I agree with your perspective. However, what is the proposed resolution?

[dontito]

If you are unable to get a substitute motor or have your current one refurbished, then a new turbocharger is required.

Do you have any knowledge or information about code 244C00?

Causing a malfunction in the drivetrain. The intercooler hose is moist.
