Moving the actuator arm isn't a remove the turbo job, can be done in place with some swearing.

As said, moving the actuator arm can be done with much swearing without removing the turbo. Even more swearing occurs if you lose the circlip that holds the actuator to the arm! Make sure that you do the work on a nice clear surface so you can see where the clip goes. |

Classic lost boost pressure code, so it'll be a leak in the boost hoses somewhere. It's extremely unlikely to be the turbo, and a replacement turbo isn't plug n play anyway. Hyundai Ioniq 5 Ultimate.

If it was just a hose would it still cause the weird, jerky mis-fire feeling? |

Yes, anything that causes running outside of the tight parameters these engines run at can cause strange running issues. It's better to replace all the hose before going down the turbo route, as the hoses are known to fail. Hyundai Ioniq 5 Ultimate. The family car.

Does anyone make a complete set of inlet, turbo and intercooler pipes? LR items are a tad pricey |

P0299 Errors that have occurred on this FL2 Site have all been Air Intake Path problems, that is with Hoses, EGR, TURBO and/or ACTUATOR. (or even a sensor failure in one case)

Handy to know. She's not done the restricted performance thing yet. She still pulls well if I floor it, just jerks about under minimal throttle input. |

If no 'Limp Home' mode then best to follow Nodge's advice as the symptoms are similar to the 'old fashioned' mixture control being wrong.
