Beschreibung
Zusammenfassung:	A method for monitoring urea concentration and quality in a urea solution stored in a tank of an SCR system. The system comprising a pump driven by a motor and the pressure of which is controlled by a controller. The method comprises the steps of: - measuring a parameter value characteristic of the energy transmitted by the motor to the pump; - determining a urea concentration value based upon the parameter value characteristic of the energy transmitted by the motor to the pump.
