The invention relates to a method pertaining to an SCR system for exhaust cleaning which comprises a container (205), to accommodate a reducing agent, and a dosing unit (250). The method comprises the steps of - continuously detecting (S410) discrete indications for remaining volumes of reducing agent in said container, - setting (S420) a first value (V1-VN) for said remaining volumes to latest detected indications for remaining volumes of reducing agent, and - setting (S430) second value (V1-VN) for said remaining volumes to latest detected indications for remaining volumes of reducing agent, for determination of a detected reducing agent volume dosed (Vdetect). The invention relates also to a computer programme product containing programme code (P) for a computer (200; 210) for implementing a method according to the invention. The invention relates also to an SCR system and a motor vehicle (100; 110) equipped with the SCR system. |
