Ford Mondeo MK4 2.0tdci 140km zetec - After warming up the turbine stops working

Hello everyone and I ask for help I have a Ford Mondeo mk4 2.0tdci 140km zetec from 2008 the problem is that when the engine heats up to its temperature a yellow exclamation mark lights up, information on the computer FAULT ENGINE and the ESP lights up The engine is getting muddy turbo stops proccessing I connected car under the computer error P003A was displayed I have no idea what this error means and also jerked at 2000 rpm. in each gear I disconnected the air flow meter the jerking stopped and also for some time the turbine did not turn off but after 60km the message FAULT ENGINE lit up again, YELLOW EXCLUSION IS LIGHTED AND ESP today I changed the air flow meter the engine sometimes jerks
but I still have a problem with turbo I don't know whether to replace the turbine or the controller.

in the workshop you would pay half of what you gave for the flow for the diagnosis, but exchange turbo now

P003A: 17-2F Position programming limit of turbocharger / supercharger pressure control mechanism exceeded, circuit voltage above threshold.

the diagnosis was made in a workshop there I was told that I should replace the air flow meter and as for the error P003A I was told that it could be the fault of the turbine controller itself or the sensor

The turbine itself is rather functional. The error generates a sensor, computer or some bad connection in between.

I read on the internet that the culprit may be the turbine controller, but I have no idea where to look on the internet, I haven't found anything, I don't even know what this sensor looks like

Added after 4 [hours] 2 [minutes]:

can the turbocharger variable geometry position sensor be responsible?

I changed this sensor of the variable geometry of the turbocharger and my question is whether after the replacement I have to do turbine calibration, some mechanics say yes and some say no

Hi, I currently have the same error, I don't know how to solve it either. I have it right after starting the car. And every time. Have you solved the problem.

Hello, and how did the PAns deal with this problem? I have the same symptom immediately after driving 5m pops up engine fault

Hi I played with the pear on the turbine and the problem was solved. The error does not pop out.

I have a similar problem, sometimes the engine light illuminates, the turbo is broken, once it pulls the car and once at all, it drives 60 / h for 2-4km and then I press the gas and the car does not pull ...

Do you know what was the cause in your cases?

Some of me had large clearances in the turbine on the shaft, which is controlled by geometry. After replacing the turbine OK
