BMW Questions? Ask a BMW Repair Expert for Answers.
I will provide an honest answer. I trust this will be appreciated. Please remember that a low rating PUNISHES me for being honest and that I receive nothing for my time until a positive rating is clicked..
you have asked, what could be the problem?
the answer is that there are a few things that can cause this. the first is a simple low Freon level. the second is an issue with the air directing blend doors behind the dash, and the third (least likely) is an issue with the actual climate control computer malfunctioning. This system is pretty complex so the best way to diagnose and eliminate guess work would be to have a proper test plan run with a BMW/MINI scan tool. If you need a shop for this check out www.bimmershops.com or www.bimrs.org

I know that. that is why I said a BMW/MINI scan tool and directed you to the best repository of BMW/MINI specialists
BMW is the bigger service business, there are no mini-only specialists. most BMW specialists also know and work on minis
and all of the diagnostic equipment is the same, which is why the two sites I recommended - despite focusing on BMW - are your best chance at finding a qualified and experienced non dealer that can handle this problem
they test for this by plugging in a diagnostic computer and monitoring all readings in the AC system (all inputs and output readings) and then can also manully command things to happen from the diagnostic computer to see which actually happen or which don't.
the diagnostic computer will the generate further tests based on outcomes of initial testing

unless you have a BMW/MINI only code reader that costs $1000+, then unfortunately it will not read any codes related to this. Basic consumer readers only read out emissions impacting faults when the check engine light is on.
I am not sure what you have read but there are no on-board diagnostic codes that can be read out to address this issue except by using a high end scanner as I have described.
that is not a legitimate diagnostic process
the faults need to be read
feel free to follow the instructions that are posted online, they will not lead to a resolution, I can assure you.

thank you in advance.
this does not fully diagnose the issue or prevent you from having to take the car in. there is no value in bothering with this.
