BMW 3: Problems with electric fan and e-box fan

Loss of engine power

I have a BMW 3 and have problems with reduced engine performance. The error codes are 2EEF (electric fan self-diagnosis) and 2F71 (e-box fan control). The fan runs continuously as soon as the engine is warm. Where should I look for the problem first?

Start by checking the electrical connections and wiring for both the electric fan and the e-box fan control. Look for any loose, corroded, or damaged connectors that might be causing the issue. Let me know if you find anything unusual or if you need further assistance.
