Check HKL ECU and wiring. Probably water ingress.

HVAC = heating ventilation air conditioning. I don't think what you found is the correct control module. Probably should have been the HKL or HKFM.

Here's a link to the BMW fault code site...input your BMW hex code then select accordingly to view the possibilities based on the correct control module for you car: https://bmwfault.codes/
