P1056 BMW 325i code

Good to all

I tell you, I have a BMW 325I with a fault code
what happens is that the car does not start but the whole engine revolves but
it gives me a fault code the P1056 BMW - Valvetronics Actuador Motor Power Supply what I realized is that the valve does not turn as it should be if someone has an idea of ​​which it would be of great help:

That code indicates that the fuel dosing actuator is not working can be due to false contact or it can have been burned if you tell me what kind and model of ECU is I can guide you how to test the same greetings
