Abstract
In a method for operating a tank device of a motor vehicle, with the tank device having a tank and a tank ventilation device with at least one switching valve, an excitation current can be applied to the switching valve, and the switching valve opens only when the excitation current exceeds an excitation current threshold over a certain period of time. Provision is hereby made to apply an excitation current which is greater than the excitation current threshold, at least temporarily, in a first mode of operation to the switching valve for heating purposes, also when ventilation of the tank is not governed by a control unit of the tank device.
