I have a really nice A4 Cab Final Edition, it was brought from the local dealer last week and it has all the bells and whistles on it. The only issue is that I have noticed that the climate control doesn't blow cold, not even in the slightest bit cold. Also there is no difference in temperature when in 'ECON' mode or not. I know it's a cab, but it gets a bit windy driving on the motorway, so the roof is up. So, should the cab have air conditioning as standard and is mine broken or has the air con been substituted for the disappearing roof?
