Auxiliary turbo coolant pump ....bad = loss of hp ?

Bought a W222 car seams slugglish with no bottom end trq tech looked at the car and said auxiliary turbo coolant pump is not working or going bad and that could rob huge amount of power.
Tech also said that that it doesn't throw a code if pump goes out it just kinda goes in limp mode by reducing power.

Find another tech, makes no sense. Or pick up what he is putting down and start the money flowing to him and into the car.
