P0234 Overboost via Obd2

Hi there! right had an overboost P0234 on C Class w204 c320 cdi 2008, engine om642.
both Map sensors are new, intake connections are tight, also changed cracked intercooler hoses, electronic actuator is new, turbos vanes are moving freely when removed actuator the linkage arm moves easy freely.(turbo wasnt opened), blades not wobbling or any play there, spins nice.
still got some amount of smoke black with a bit of white, and car goes in limp mofe, ran out of ideas what could be, or it could be turbo inside, or can pay attention to egr or something else.
