Just came back from driving in the lowest temperatures so far since I got my A4. The snow flake came on on the outside temperature display (I don't have the computer, just the temperature display). Next to the snow flake, there was a plus-sign. I couldn't find a reference to it in the manual. Does anyone know what it is? My guess is it will change to a minus-sign below 32 degrees.

Also, does this car ever pull harder at these temperatures! I love it. And two 90 degree turns in first gear, full gas, on wet pavement... No slip... No spin... Just GO! :) I love it!

Maybe the "+" is in reference to the temp. of zero. Below zero would have an indication of "-" and above zero is "+". I've only had my A4 for a month so its a guess.

the '+' means that the temp is above zero degrees.

In either the Farenheit or Celcius temperature scales, you can have positive or negative numbers. The temperature reading uses the "+" to denote a number over 0 in any of the scales. I haven't hit negative numbers yet, but I assume a "-" symbol will appear when that happens.

The snowflake symbol comes on when temperatures approach freezing. I have my climate control set up with metric units so the snowflake comes on around +5C (which is about +41F). So in your case, the snowflake probably begins to show up somewhere around 32-41F (or any temperatures below that), and since these are both postive numbers in the Farenheit scale, you'll get the "+" symbol. Once you get below 0F, I imagine you'll get the "-" symbol in front of the number.

The "+" or "-" symbols are independant of the snowflake and actually modify the number. (Of course, if you're following the metric scale, water freezes at 0C and anything below zero or with the "-" symbol will always have the snowflake accompanying the temperature. WIth Farenheit, this isn't always the case, since water freezes at +32F).

Maybe you folks should switch to metric ;-)
