Does anyone with a modern (2004) MB fitted with the Thermotronic (intelligent) Air Conditioning system (not the Thermatic AC system) know how to make it supply fresh air from the outside?
I have studied the OM in detail, and I can find no way to achieve this very simple function. Apart from opening the windows/sunroof that is.
I thought that I had defeated the 'brain' at one stage by setting the internal temperature control to the indicated external temperature, but all that achieves is the blower stops running...
Surely this normal requirement has not been overlooked. Or have I missed something?
