Mini Countryman AC Issue Temperature Sensor
Summary of the thread
A 2012 Mini Countryman is experiencing an AC issue, with an error message indicating a problem with the temperature sensor in the heat exchanger. The owner suspects the air conditioning control unit might be faulty. Another person with a similar experience suggests that the fluctuating temperature gauge could indicate a faulty sensor related to the heat exchanger. The recommended solution is to have the vehicle checked at a workshop to confirm the exact issue, which ultimately led to the replacement of the defective sensor, resolving the problem.

Cooling system seems fine, no leaks or anything obvious. The temperature gauge in the dashboard is showing odd readings, fluctuating a lot. You think it's definitely the same issue? What exactly went wrong with yours?

Yep, the fluctuating temp gauge is a dead giveaway. For me, it ended up being a faulty sensor related to the heat exchanger. I tried some basic sensor calibration stuff but no luck. Best bet is to get it checked at a workshop, they can pinpoint the exact sensor and confirm if the control unit is also playing up.

Cheers for the advice I got it sorted. Turns out the heat exchanger temperature sensor was indeed defective. Cost a bomb at 980€ but at least the AC is working again!

Sounds familiar! My Mini Countryman had similar symptoms last year with the AC and some weird temp readings. Did you check the cooling system at all? Is your temperature gauge acting up too?
