定期的维修保养对于宝马车辆保持良好性能、延长使用寿命至关重要。在保养方面，机油更换是基础且关键的环节。宝马发动机对机油品质要求较高，建议使用符合宝马认证标准的全合成机油，根据车辆使用情况，每 1 万公里或 1 年进行更换，以确保发动机内部部件得到良好润滑，减少磨损。

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.

空气滤清器和空调滤清器也需定期更换。空气滤清器能有效过滤进入发动机的空气，防止杂质进入气缸，若长期不换，会导致发动机进气量不足，影响动力和油耗。空调滤清器则关乎车内空气质量，建议每年更换，尤其在雾霾天气频繁地区，更要缩短更换周期。

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.

刹车系统保养同样不容忽视。定期检查刹车片厚度，当刹车片磨损至极限厚度时，应及时更换，同时检查刹车盘磨损情况，必要时进行光盘或更换。刹车油也需定期更换，因其具有吸湿性，水分过多会降低刹车性能，一般每 2 年或 4 万公里更换一次。

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.

在维修方面，一旦车辆出现异常，如异响、抖动、故障灯亮起等，应及时送修。选择专业的宝马维修店或 4S 店，利用其专业设备和技术人员进行精准诊断和维修。同时，车主应保留好维修保养记录，这不仅有助于了解车辆历史状况，在车辆交易时也能提升其价值。通过科学合理的维修保养，宝马车辆才能持续展现其卓越性能，陪伴车主安全出行。

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.
