Depends how much you want to trouble shoot this ....
Idrive talks to the climate system (ihka high) over can bus messages. It's possible that either The idrive ccc is faulty regardless of the climate system. You could easily unplug the climate system from can and see if idrive goes through a reboot. If it doesn't you've isolated that the climate system is at fault.
If idrive continues to reboot you're CCC might be ready for replacement.
