Hi all, With the heat we've been having, I've recently found out that my air con isn't blowing cold when both dials are set to "LOW". My econ button light isn't showing but lights up when I switch it on. I have an audi a3 tdi 140 with the climate zone type of air system. I've scanned the car and this is the fault code showing. 00483 control module for auxilary air heater sporadic 013 Any ideas? Hopefully it's just a re gas!
