Econ kills the aircon and reverts to "normal" ventilation. After pressing demist the rad fan should run continuously at low speed. If there's a problem the fan will pulse on/off at a high speed, on for several seconds, off for several seconds.
Whether you need the engine running depends on which model, needed it running with the 1.8T I had.
