Turbocharger WASTEGATE Actuator

WARNING: This page is about a different car, the 2018 Land Rover Discovery Sport. However, it is still accessible from the selected car via links, so may be relevant.
G11718896

The turbocharger wastegate actuator is attached to the compressor housing with three bolts.

The wastegate actuator opens and closes the wastegate flap allowing the exhaust gas to bypass the turbine. The wastegate actuator contains a position sensor. The position sensor and the actuator motor are connected to the Powertrain Control Module (PCM). The actuator is controlled by Pulse Width Modulation (PWM) signal from the PCM.

If a fault occurs with the turbocharger wastegate actuator, a Diagnostic Trouble Code (DTC) is registered in the PCM.
