A wastegate is a valve that regulates the flow of exhaust gases in an internal combustion engine. It is an important component of the engine's turbocharging system, as it helps to prevent the turbo from overspeeding and potentially damaging itself or other engine components.

There are many signs of a stuck closed wastegate, including the check engine light coming on, excessive boost pressure and power, reduced fuel efficiency, overheating and potentially engine damage if the issue is left unfixed.

In this article, we will discuss what can happen if the wastegate becomes stuck in the closed position, including the signs and symptoms of a wastegate stuck closed, as well as how to diagnose and fix the problem.
