CLS 320 cdi P0244 error code

[Andrezy51]

Hey guys I have a 2006 cls 320cdi. And I have this error code p0244 . I have done some research and. I checked the turbo actuator circuit plate. And it seems fine. (See attachment). Also I tried to se if the actuator arm moves but it does not at all when the engine is on or at standstill or during rev) help guys what’s the next move?

check cooler hoses, split may be difficult to find but it is most common culprit. Then see intake manifold flaps are moving, watch live data all pressure sensors are inline together... SDS can do some individual tests according the fault code...
