Climate control problem?

interesting, I have a similiar problem, in that the AC works but only when the temp is in the LOW setting

any other setting it blows hot/warm -- the auto adjustment of the temp is fubard

i have had VAG-COM on it and get the following code

I'm guessing stepper motor / vent flapper motor. They live behind the glovebox. Can you cycle through basic settings using vcds lite? If not try and get the full version to run some basic tests.
