Unhappy V50 1.6D2 D4162T 2011 - "Engine Power Reduced" Message

Hello,

I have a problem with my V50 (1.6 D2 2011). There is message appearing - "Engine Power Reduced".

After few diagnostics (also in official dealer service) I`m receiving the following error codes:

ECM-P256500 Turbocharger Boost Control Position Sensor “A” Circuit High
ECM-P259900 Turbocharger Boost Control Position Sensor “A” Performance - Stuck High
EPS-U300616 Control Module Input Power “A” - General Electrical Failures - Circuit voltage below threshold

Also when the message appears on my dashboard, I have the feeling that the car switches off one of the cylinders and the turbo charger, because when turn off the car engine, there is a noticeable vibration.

When turn off and then turn on the engine, there is no problem and I can drive the car until the engine gets to the certain stress point and the message appears again.

Replaced the turbo charger + fuel filter + MAP sensor... nothing.

Please help with some advice how to proceed.

Default Actuator Details

I'm having a similar problem. Could you give more specifics on the actuator? Do you know what the part number is? Where is it attached? Thanks in advance! Nick

Hi! I have the same issue as you. Also, I was searching which one is actuator valve A and I couldn't find it. Can you please accept if it is something like in the image?



Thanks a lot!
