Abstract

Method and device for emptying a conveyor unit (1) for a liquid additive (particularly a urea water solution). The method comprises at least the following steps: a) producing an electrical connection (2) by means of a currentless switch (3) which is set up to produce an electrical connection (2) if a temperature fails to reach a limit temperature; and b) emptying the conveyor unit (1) when the electrical connection has been produced in step a). The invention is used particularly in SCR systems for the exhaust gas treatment for motor vehicles (11).
