    Abstract: A device for supplying a liquid additive for a motor vehicle includes a tank for storing the liquid additive and a delivery unit for delivering the liquid additive out of the tank. A sensor emits and receives waves and is configured to measure a fill level of the liquid additive in the tank by way of a propagation time measurement of the waves along a measurement path to a liquid surface in the tank and back to the sensor. The measurement path runs at least partially through a measurement duct. At least one back-flushing line ends in the measurement duct so that flushing of the measurement duct to the tank can be performed, in such a way that the measurement duct is kept clean and/or is cleaned. A motor vehicle having the device is also provided.

    Abstract: An injection device for the metering or addition of a liquid additive into an exhaust gas treatment device, includes an outlet region to be brought into contact with the exhaust gas treatment device, a connector region spaced apart from the outlet region and having a fluid-line connector, and a duct or channel for the additive extending from the connector region to the outlet region. A valve controls the metering or addition of the additive, and at least one heat-flow adjustment device defines a direction of freezing in the duct from the outlet region towards the connector region. A method for freezing an injection device, a method for producing an injection device and a motor vehicle are also provided.
