I ordered that very same part for a problem that ended up being an issue with the IHKA controller. So it may or may not fix your issue.

Mine was reporting the stratification flap + a Lin Bus error, but as I understand it, the Lin Bus issue will cause all the other codes to show up. I followed all the steps outlined elsewhere, included the dynamic stepper motor steps (went ahead and tried a new part just in case).

I can confirm that's the part that will fit under the glove box, below/behind the blower motor. It's really easy to access and remove/install.
