ditchman Posted December 1, 2018 Report Share Posted December 1, 2018 That is a "turbo actuator"...it is connected to the compression side of the turbo and also connected to the boost actuator which is situated on the Boshe injector pump......the turbo actuator controls the waste gate..... check the waste gate is not stuck and also check the actuator works.....(pressurise it and see if it holds its position)...............
