The disclosure proposes a method for controlling discharge of a solenoid valve arranged in a vehicle, wherein the solenoid valve comprises an inductor and a plunger arranged to be moved by the inductor from a hold position to a rest position, whereby the solenoid valve is opened or closed. The method comprises stepwise discharging the inductor by discharging the inductor at a slow decay rate during an operating time period during which a final part of a movement of the plunger from the hold position to the rest position takes place. The method further comprises discharging the inductor at a fast decay rate during at least one other time period, wherein the plunger is stagnant during at least a part of said other time period, wherein the fast decay rate is faster than the slow decay rate.
