The invention relates to a method for controlling a waste heat recovery system associated with a combustion engine of a vehicle, the waste heat recovery system comprising a working fluid circuit; at least one evaporator; an expander; a condenser; a reservoir for a working fluid and a pump arranged to pump the working fluid through the circuit, wherein the at least one evaporator is arranged for heat exchange between the working fluid and a heat source, and wherein the waste heat recovery system further comprises a cooling circuit arranged in connection to the condenser. The method comprises the steps of: predicting a shutdown of a combustion engine associated with the system; determining if a predetermined requirement is fulfilled; and if so reducing the temperature in the waste heat recovery system prior to combustion engine shutdown.
