The Passenger side turbo is fine as the fault code and limp mode only happen when the drivers side turbo is engaged, which happens above a certain RPM threshold.

@Disco_Mikey really appreciate your input. What do you mean by it not being a valid DTC? This is the code being displayed by GAP Tool and is DTC quoted on the initial main dealer report. See below: ![]()

This is a great help Col. Thank you. Gives my guy a bit more clarity on what to check out. Assume it’s the same engine? |

As the control module has a stepper motor in it, I was just wondering if it needs calibrating in some way if it has been replaced, I think Disco-Mikey may be the person most able to answer that though.

Everything points towards a faulty actuator...

Ok. No calibration procedure has been carried out on the car. The mechanic mentioned that there might be one but if so he needs to find out what it is. Is the calibration procedure something that’s done on the bench? If so I believe that the Turbo Guy is supposed to have done all this.

Calibration is done via diag, with the unit fitted to the car
