Thanks for the explanation. But wouldn't a good fail safe be making it in reverse? What would happen if it couldn't expel the boost into the atmosphere?

The reason they fail is because the door hinge system wears out and doesn't seat properly. Therefore the boost never builds up properly, and causes all kinds of issues since the motor thinks the pressure should be there. If it couldn't dump the boost to regulate the pressure you would end up with over boost. That would either put you into limp mode, or destroy the motor/turbo. The wastegate goor is held shut via a vacuum solenoid and opens/closes to regulate pressure. |
Thank you that clears things up
