1、渗漏油液：这个在用了一定年限，比如10几万以上的宝马车上容易出现，这个主要就是相应的密封垫、密封圈、油封等出现老化损坏导致，不要一上来就换总成。

1. Leakage of oil: This is prone to occur in BMW cars that have been used for a certain period of time, such as over 100000 kilometers. This is mainly caused by aging and damage to the corresponding sealing gaskets, sealing rings, oil seals, etc. Do not replace the assembly immediately.

2、烧机油：对于老款的宝马车，比如N系发动机车型，烧机油一般是气门油封损坏导致的，单独更换这个小东西就行。对于B系发动机，目前听到多的是B48发动机机油消耗快，这里主要有2个原因，一是气缸盖罩存在裂缝；二是机油滤底座损坏，对于机油滤底座，目前网上已经铝合金材质的升级版。

2. Oil burning: For older BMW cars, such as the N series engine model, oil burning is usually caused by damaged valve oil seals. Simply replace this small item separately. For B-series engines, the most common reason heard so far is that B48 engines consume oil quickly. There are two main reasons for this: first, there are cracks in the cylinder head cover; The second issue is that the engine oil filter base is damaged. For the engine oil filter base, an upgraded version made of aluminum alloy material is currently available online.

3、B48爆水管：其原因是发动机在某些工况下，真空调解阀关闭，冷却液流不到缸盖，从而使缸盖局部温度过高，这就造成了水管缸盖测的接头容易高温老化。另外，在发动机运行过程中，抖动会在接头和水管处产生应力，也会加速塑料接头的疲劳老化。这个同样有改良、加强的回水管购买，有加强尼龙塑料的，有硅胶的，还有铝合金接头，1、2百就能买到。

3. B48 burst water pipe: The reason is that under certain operating conditions, the vacuum regulating valve of the engine is closed, and the coolant cannot flow to the cylinder head, resulting in a local high temperature in the cylinder head. This causes the joint of the water pipe cylinder head to be prone to high temperature aging. In addition, during engine operation, shaking can generate stress at the joints and water pipes, and also accelerate the fatigue aging of plastic joints. There are also improved and reinforced return pipes available for purchase, including reinforced nylon plastic, silicone, and aluminum alloy joints, which can be purchased for 1 to 200 yuan.

4、空调出风口面板损坏：有的车主可能花了1、2千去更换原厂的总成，实际只需单独更换出风口面板就可以了，网上买零件也就100-200的，动手能力强的自己也能搞定。

4. Damaged air conditioning vent panel: Some car owners may have spent 1000 to 2000 yuan to replace the original assembly, but in reality, they only need to replace the vent panel separately. Buying parts online can cost 100-200 yuan, and even those with strong hands-on skills can handle it themselves.

5、分动箱损坏：一般是内部摩擦片烧蚀，更换摩擦片就好。

5. Transfer case damage: Generally, the internal friction plates are burned out, just replace the friction plates.

6、X5/X6手刹损坏：这个一般是内部电机的负极熔断导致的，焊接上就行，多直接更换这个小电机，几百块就搞定。所以，在花几千元换总成之前，不妨仔细检查下这个电机。

6. X5/X6 handbrake damage: This is usually caused by the negative pole of the internal motor being blown, just weld it on, and replace this small motor directly. It can be solved with a few hundred pieces. So, before spending thousands of yuan to replace the assembly, it's worth carefully checking this motor.

7、内门把手、车窗按键区域黏糊糊：这个一般是用久了之后，零部件老化脱胶导致的，去网上购买改良件安装，一套下来几百块就搞定。

7. The area of the inner door handle and window buttons is sticky: This is usually caused by the aging and debonding of components after prolonged use. You can purchase improved parts online for installation, and it takes a few hundred yuan to get it done.

8、真空泵漏油：一般是内部密封圈或单向阀损坏，网上购买相关零部件更换就好，零件费200以内

8. Vacuum pump oil leakage: Generally, the internal sealing ring or one-way valve is damaged. Simply purchase relevant parts online to replace them, and the parts cost is less than 200 yuan
