For me the clima menu became active and actually usable (yours doesn't seem to be working correctly) after I updated my clima unit to a later firmware version:I am a a loss here ... I just Switch the clock spring and now nor fault but still impossible to enable hsw bc the button deos nothing and the setup on climate doesn't have a bitton too ...

I installed 2010, this also enabled air care menu. And also I could change the temps on the mib screen instead of them being grayed out.
Regarding the steering wheel heater button on the wheel, please check the following coding:
Module 19 (Gateway) - Adaptation - Multifunction steering wheel control module - Heated_steeting_wheel_button - active
