1. A monitoring and measuring device for an air supply system of a vehicle, the device comprising:
a compressor adapted to provide compressed air;
a defined volume arranged downstream of the compressor to receive the compressed air from the compressor,
a shut-off valve arranged downstream of the defined volume to shut off air flow out of the defined volume, wherein the shut-off valve is an overflow valve designed to open as soon as a preset target pressure is reached,
a pressure sensor provided at any position on a pressure line between the compressor and the shut-off valve and configured to measure a pressure that builds up in the defined volume, and
a computing unit adapted to determine a pressure change over a filling time in the defined volume based on the signal indicating the pressure measured by the pressure sensor.
