Variable Intake Manifold
Runner Motor V183
The variable intake manifold motor is bolted to the
intake manifold.
Task
The motor is actuated by Engine Control Module
J623 depending on engine load and speed. The
motor actuates the change-over flaps via a shaft and
switches to the torque (long runners) or the output
position (short runners).
Effects in the Event of Failure
If the Variable Intake Manifold Runner Motor V183
fails, intake manifold change-over is no longer
possible. The intake manifold remains in the position
in which the change-over flaps were located at the
time of failure. Power and torque are reduced.
