intermittent aircon fault - stops working in the dark
on my 2004 B6 Audi S4 Avant I've noticed that my aircon stops working in the dark.
This happens whether I have the aircon set to auto or even if I've manually set the fan speed and temperature.
Some examples:
It's almost as if there's a UV or light sensor somewhere?
(Incidentally - there IS a little box attached to the top of the windscreen by the rear-view mirror. Anyone know what that is?)
Any thoughts?

Some examples:
- at night the aircon will not come on - unless I hit the ECON button which will then blow some air through but it doesn't feel like it's aircon
- if I drive into a tunnel the aircon will stop blowing but will start again as soon as I come out of the tunnel
- similarly if I drive into a covered carpark
- even if I drive under a flyover / bridge the aircon will stop blowing for the split second it takes me to pass under the bridge

Anyone resolve the mystery of your A/C fan turning off randomly and then turning back on right after

I was on a long drive for vacation and turned on the A/C (Auto button) during my drive and the car..
