1. A method for producing a reinforcing element for reinforcing a structural element in a motor vehicle, the method comprising:
pultruding a carrier element, which has a longitudinal axis extending along a longitudinal axis of the structural element in a use state, wherein the carrier element has multiple outer surfaces extending in the direction of the longitudinal axis;
arranging an adhesive on at least one outer surface of the carrier element;
cutting the pultruded carrier element to length; and
extruding or overmolding an additional element onto the carrier element, wherein the additional element is in the form of at least one wall on at least one outer surface of the carrier element, and the wall delimits the adhesive in at least one direction on the outer surface.
