Hello, is it cold on both the center and left driver side vent or just the left vent by the door?
Customer: replied 7 months ago.
there are 4 vents 2 outer(by doors) and 2 inner(by MMI screen) all blow warm air except the center one by MMI on drivers side. It blows ice cold air when the heater is on

ok the issue will be a blend door motor, do you hear any clicking or popping by the dash?
Customer: replied 7 months ago.
no, I have a vagcom, and thought I ran all the tests to make sure everything is working. Do you know what Audi would call that door. Is it Blend Door Motor?
Expert:  Lou P. replied 7 months ago.
yes blend door, i do not know the designation off the top of myhead though but you should be able to run a sweep of the motors.
