The present invention relates to a method (100) for cold start optimization of an internal combustion engine (10) comprising: determining (110) a start of an engine preheating device (12); transmitting (115) a selected coolant temperature Tcool_trans to an engine control unit (14); and adapting (140) the selected coolant temperature Tcool_trans transmitted to the engine control unit (14) to a current coolant temperature Tcoll_current during a time interval Δt following the start of the internal combustion engine (10). The present invention further relates to an auxiliary control unit (22) which is configured to execute the method (100).
