Its actually a heater.
Why Heat you might ask?
Well its activated when the ambient temperature drops and there is a possibility of water vapour building up on colds starts in the breather. This might in certain cold conditions form ice crystals and these crystals could then fall into the turbo inlet damaging the impeller vanes.
