In a method for testing and repairing an injector for injecting fuel into the combustion chamber of an internal combustion engine, wherein the injector includes a nozzle, a restrictor plate, and a control valve, and a nozzle clamping nut which holds together said parts and by way of which said parts are fastened to an injector body of the injector. The functional components-nozzle, restrictor plate and control valve-are separated from the injector body. A connection piece serves to connect the functional components to a test bench is screwed to the functional components with the aid of the nozzle clamping nut to form an injector module. The injector module is connected to a test bench and subjected to testing, and afterwards optionally repairing.
