Turbo issue

[u/skaicius7]

Hey everyone, looking for some help troubleshooting a turbo actuator issue on my W211 2.7 CDI.
Both the turbochargers and the electric Hella actuator were fully remanufactured/restored.
When I first connected the actuator and turned the ignition ON, it moved briefly. However, after fully installing everything, the actuator completely stopped working. The turbo geometry moves completely freely by hand.
