Very new to my A3 so dont know what the norm is for the Climate control. I have set it at 19 because in the book it states if you set it at 18 it wont adjust automatically just use full fan speed constantly. I cant seem to get any "cold" air coming out , my last car had CC and would drop the cabin temperature very quickly but this air con seems **** in comparison. Is there anything I can get checked out ? I got it from an Audi dealer so its under warranty ?
