How to Fix Wastegate Stuck Open

A wastegate is a valve that controls the exhaust gas flow to the turbocharger, preventing it from spinning too fast. If the wastegate is stuck open, it can result in reduced turbocharger pressure and engine performance. The wastegate actuator is responsible for controlling the position of the wastegate valve.

If the actuator has failed, it needs to be replaced or rebuilt to ensure proper wastegate function. Ignoring a stuck wastegate can cause long-term damage to the engine, so it’s important to address the issue as soon as possible.
