Hey folks. I have an '05 Allroad Quattro with the 2.7T and 106k, and I can't get heat without being in ECON mode. When I'm not in ECON mode, and I want heat I only get cold air. Both hoses going to the heater core are hot, and the temp dial is always right in the middle with no fluctuation. Any ideas as to what would cause this? Is this a blend door situation? Climate Control Valve? Internal Temp Sensor? Something else I'm not thinking of? Has anybody had experience with this? I've read a lot about only having heat and no AC, but I've got the opposite problem.

Thanks so much in advance for your help!
