For the 3rd time in 2 months of ownership the 'Climate' has developed a life of its own. It is pumping out heat to such an extent I had to open the 'roof to let some hot air out, it was becoming unbearable. When i turned doen the cabin temp setting to 'LO' it got hotter! Settings are Auto, Econ, 69 deg Farenheit, external temp around 43 deg F. I am pretty sure it is covered by the Audi used warranty but just wondered what expert opinion/experience may suggest?
