Question Diesel engine 'swirl flaps'

Having recently read BMW car magazine I noticed an ad for replacement swirl flaps on BMW diesel engines. All I can say is WTF? Has anybody out there got any experience of having to replace this component? Could it really mean an engine rebuild? Would this be covered by a standard BMW warrantee?
