People that have upgraded from 3.0.2 (12023) have had mixed results.

Other possibilities include a communication problem between the APIM and HVAC module which may indicate different firmware in the HVAC module or the IPC (Instrument Panel Cluster), which acts as a gateway between the HVAC module (MS-CAN bus) and the APIM (I-CAN bus).
I was looking for a way to force the update again but ran out of time.

Out of curiosity, why on earth would the IPC act as a gateway between the APIM and HVAC module? I am assuming you have schematics or some kind of inside knowledge on this based on your comment.
