定期的維修保養對于寶馬車輛保持良好性能、延長使用壽命至關重要。在保養方面，機油更換是基礎且關鍵的環節。寶馬發動機對機油品質要求較高，建議使用符合寶馬認證標準的全合成機油，根據車輛使用情況，每 1 萬公里或 1 年進行更換，以確保發動機內部部件得到良好潤滑，減少磨損。

Regular maintenance is crucial for maintaining good performance and extending the service life of BMW vehicles. In terms of maintenance, oil change is a fundamental and crucial step. BMW engines have high requirements for oil quality, and it is recommended to use fully synthetic oil that meets BMW certification standards. Depending on the vehicle's usage, it should be replaced every 10000 kilometers or 1 year to ensure good lubrication of internal engine components and reduce wear.

空氣濾清器和空調濾清器也需定期更換。空氣濾清器能有效過濾進入發動機的空氣，防止雜質進入氣缸，若長期不換，會導致發動機進氣量不足，影響動力和油耗。空調濾清器則關乎車內空氣質量，建議每年更換，尤其在霧霾天氣頻繁地區，更要縮短更換周期。

The air filter and air conditioning filter also need to be replaced regularly. The air filter can effectively filter the air entering the engine, preventing impurities from entering the cylinder. If not replaced for a long time, it will lead to insufficient engine intake, affecting power and fuel consumption. The air conditioning filter is related to the air quality inside the car, and it is recommended to replace it every year, especially in areas with frequent haze weather, to shorten the replacement cycle.

剎車系統保養同樣不容忽視。定期檢查剎車片厚度，當剎車片磨損至極限厚度時，應及時更換，同時檢查剎車盤磨損情況，必要時進行光盤或更換。剎車油也需定期更換，因其具有吸濕性，水分過多會降低剎車性能，一般每 2 年或 4 萬公里更換一次。

The maintenance of the brake system cannot be ignored either. Regularly check the thickness of the brake pads. When the brake pads wear to the maximum thickness, they should be replaced in a timely manner. At the same time, check the wear of the brake discs and replace them if necessary. Brake fluid also needs to be replaced regularly because it has hygroscopicity. Excessive moisture can reduce braking performance, and it is generally replaced every 2 years or 40000 kilometers.

在維修方面，一旦車輛出現異常，如異響、抖動、故障燈亮起等，應及時送修。選擇專業的寶馬維修店或 4S 店，利用其專業設備和技術人員進行精準診斷和維修。同時，車主應保留好維修保養記錄，這不僅有助于了解車輛歷史狀況，在車輛交易時也能提升其價值。通過科學合理的維修保養，寶馬車輛才能持續展現其卓越性能，陪伴車主安全出行。

In terms of maintenance, once the vehicle experiences abnormalities such as abnormal noise, shaking, or malfunction lights, it should be promptly sent for repair. Choose a professional BMW repair shop or 4S dealership, and use their professional equipment and technical personnel for accurate diagnosis and repair. At the same time, car owners should keep good maintenance records, which not only helps to understand the historical condition of the vehicle, but also enhances its value during vehicle transactions. Through scientific and reasonable maintenance, BMW vehicles can continuously demonstrate their excellent performance and accompany owners on safe travels.
