The turbo actuator has stopped working on my N47 engine. Got a replacement actuator from a breakers and still the same. Run through the test with ISTA which triggers the actuator to move but it doesn't.

Thought I'd check the wiring diagram to check continuity from the actuator connector back to wherever they connect but confused by the wiring diagram. There seems to be 2 different diagrams. One titled "bottom and lowest power stage" and one titled "upper power stage and 116d ed"

Though I'd start with the bottom/low power diagram. From what I can tell pin 3 on the actuator goes to pin 7 on the X60681 connector and pin 4 on the actuator goes to pin 11 on the X60681 connector?

Went to check them and pins 7 and 11 on the X60681 connector aren't even populated?

Can someone please tell me what I'm missing?
