    Acrid smell when aircon switched on

    My 2004 C270 Avangarde Estate has developed an acrid smell which I have traced to the aircon unit. Usually the unit is permanently switched 'on' (I have had the car from new) but I have discovered that the acrid smell stops when the a/c is switched off. Is this likely to be a gassing problem...
