Problems with the automatic temperature control in the BMW 5 Series

I own a BMW 5, model year 2003, with a gasoline engine and 160,000 km mileage. I'm having problems with the automatic temperature control. Despite replacing the climate control unit including the ventilation temperature sensor, the error 9C68 cannot be cleared. However, the air conditioning works perfectly. Has anyone had similar experiences or can give me some advice on how to fix this problem?

(Translated from German)

A BMW 5 Series owner is experiencing issues with the automatic temperature control, specifically an error code 9C68 that persists despite replacing the climate control unit and ventilation temperature sensor. The air conditioning functions correctly, but the error remains unresolved. Suggestions include checking wiring, blend door actuator, ambient and interior temperature sensors, and ensuring the control module is up-to-date and functioning properly. If these steps do not resolve the issue, consulting a professional mechanic is recommended.

I don't understand the question: The climate control unit is the control unit and it is brand new and does not need to be programmed.

Check the fuses related to the climate control system to ensure none are blown or faulty. A simple fuse issue can sometimes cause persistent error codes. If everything seems fine, it might be best to consult a professional mechanic for further diagnosis. Let me know if this helps or if you have more questions.
