What is the BMW air conditioning auto function?
2 Answers
BMW air conditioning auto is the automatic mode of the air conditioning. When pressed, the air conditioning will operate in automatic mode, automatically adjusting the airflow and the compressor's engagement based on the set temperature and the actual ambient temperature. If the car makes a vibrating sound as soon as the air conditioning is turned on, it may be due to the following reasons: 1. Dirty air filter: A dirty air filter can cause excessive noise and abnormal sounds. 2. Debris in the blower fan blades: Debris in the blower fan blades can cause abnormal sounds. You can test this by turning on the blower without starting the engine to see if the sound appears. If it does, the issue is likely with the blower. 3. Fan issues: Deformed fan blades or a damaged fan motor in the car's air conditioning system. 4. Worn clutch bearing: A worn clutch bearing in the air conditioning pump can cause the engine sound to become louder when the air conditioning is turned on. This component cannot be replaced individually; the entire air conditioning pump assembly must be replaced.
As a long-time BMW owner, I particularly appreciate the convenience of the AUTO air conditioning feature. After starting the vehicle, simply pressing the AUTO button on the center console allows the system to take over everything: it uses built-in sensors to monitor the cabin temperature in real-time, then automatically adjusts the fan speed and cooling or heating output to quickly reach your preset target temperature. For example, on scorching summer days, it blasts cold air to rapidly cool down the interior; once the temperature stabilizes, it gently maintains the set conditions. This eliminates the need for manual adjustments while driving, reducing distractions and enhancing comfort and safety. You can also toggle between recirculation and fresh air modes on the screen to tackle pollution or high-speed wind resistance issues. Overall, this intelligent feature transforms driving into a pleasure, especially during long journeys where it significantly improves physical and mental comfort.
