Abstract

The invention relates to a method for determining safe start-up of a reducing agent provision configuration during relatively cold conditions comprising a reducing agent tank (205), a pump unit (230), at least one dosing unit (237) for providing said reducing agent to an engine emission control system of a combustion engine (231). Hereby at least a portion of the reducing agent is frozen in said tank (205). This is performed by determining if a determined volume (V) of a configuration of liquid reducing agent exceeds a predetermined threshold volume (Vth). The volume (V) of the configuration (Config) of liquid reducing agent is determined on the basis of a temperature change rate (Tprim) of the reducing agent in said tank after de-activation of heating, a level (H) of said reducing agent in said tank (205), a heat transfer coefficient (Coeff) relating to heat transfer between frozen reducing agent and fluid reducing agent, said configuration (Config) of fluid reducing agent and a size of the outer surface (A) of said configuration (Config).The invention relates also to a computer program product comprising program code (P) for a computer (200; 210; 500) for implementing a method according to the invention. The invention relates also to a system for determining safe start-up of a reducing agent provision configuration and a motor vehicle (100) equipped with the system.
