Very little turbo boost (needle goes part way into the orange > band and holds steady under full throttle in any gear.) > Local dealership checked the computer system this morning - no fault found. > Suggested I go away and see if it clears itself.

If you live somewhere flat like Holland or the Utah salt flats then you can simulate load by leftfoot braking, but this is not as successful as when the footbrake is applied the max boost pressure is lowered.
