Instead of a dump valve and a vacuum or pneumatic wastegate control via actuator, there is an Electronic Stepper Motor / Actuator attached to the side of the turbo.
This ‘motor’ controls boost by changing the angle of vanes inside the turbo.
It is in fact a separate component to the turbocharger itself and as such it can be replaced independently.

Very generally, if there is no physical problem with the turbocharger (e.g. no movement in the turbine / compressor to indicate wear or a squealing noise as a result or leaking oil etc.). But the vehicle’s computer forces limp mode, and /or engine warning light comes on, and perhaps you cant rev the engine above 1500 rpm as a result. Or there is a more general problem with boosting it MAY be due to a fault in the Stepper Motor only.

It would be a good idea to have the vehicle scanned to check if a fault code for the Stepper / Actuator shows up.
You might end up with a code similar to this: P1251 (34) – Turbocharger stepper motor circuit (intermittent)

If so, you will be better off replacing just the component that is faulting.
Why pay for an entire new turbo if all you need is to replace the stepper?

Up until now, it was only sold as a complete unit – both actuator and turbo together.
This was very expensive and unnecessary, as often it was EITHER the turbocharger OR the stepper motor that were faulty, hardly ever both units at once.

Get a faster solution (no need to remove the entire turbo from the vehicle) AND save several thousand dollars by purchasing and replacing JUST the Stepper!.
