On the 5k, the a/c head will not turn on the compressor if the temperature
is below a certain point. I think it's around something like 34 deg. F., or
maybe 42 deg-I can't remember. Yours might have this as well.
On a similar note, do all Audi's run the compressor with the defroster? I
though that this was normal, and my 5k does it.
