Can VPOD be tested/actuated with DDDL/laptop/nexiq alone or is there an additional component needed?
2004 series 60 14L
No power/ boost
Harness isolated and load tested okay. Delta and tubes Okay. Air supply pressure okay. Actuated bench tested okay. Turbo vane lever moves freely.
No air is ever delivered to actuator.
Will make boost when actuator is disconnected and lever pushed up and engine throttled up.
New fuel filter and pump recently.
