Hi guys, I just logged into this official DTG site. (BTW I am German). I noticed that the engine ventilation of the DB BR 143 is buggy. If you turn the switch to position "on" and not "automatic" it will go on exactly as it should. But if I then turn the engine ventilation to "Off", it won't go out. This only works properly if the switch is in the "Automatic" position, then the engine ventilation goes out.
