Vehicle presented to workshop in Limp Mode with harsh gear changes evident too.

This issued had first surfaced 9 months ago. Previous repairs focused on the turbo boost control servo area.

It was now a permanent fault, with the engine MIL illuminated.

Confirmed vehicle in limp mode, with reduced power. Also, engine remaining MIL illuminated confirming the current fault.

Road tested vehicle and confirmed that after a code clear, limp mode would quickly return after a moving the gear selector a couple of times.

Ended up requiring a new turbo assembly to rectify this fault.
