宝马汽车时间长了可能会出现一些不良反应，作为车主的您这个时候就要及时进行处理解决，不要让小问题拖变为大问题，下面
济南哪里有宝马汽车维修的小编讲三个问题。
BMW may have some adverse reactions after a long time. As the owner of BMW, you should deal with and solve these problems in a timely manner. Don't let small problems turn into big problems. Next, there are three problems mentioned by the BMW maintenance staff in Jinan.
1.车下滴漏出一摊莫名其妙的液体，且冷却液的液面高度下降。
1. A pool of inexplicable liquid drips out under the car, and the level of coolant drops.
病情原因：通常情况下造成滴漏的原因是连接冷却液箱和发动机间的橡皮管有裂缝。绿色保养：变质的冷却液防锈品质下降，不但容易导致散热器、管路、软管等部件的损坏，而且因冷却液的主要成分是乙二醇，滴漏到地上也会造成环境和空气污染。
Cause of illness: Generally, the cause of dripping is that the rubber pipe connecting the coolant tank and the engine has cracks. Green maintenance: Deteriorated coolant has poor antirust quality, which is not only easy to cause damage to radiator, pipes, hoses and other components, but also because the main component of coolant is ethylene glycol, which will also cause environmental and air pollution if it drips onto the ground.
但我们很难通过目测判断冷却液是否变质，所以要定期更换冷却液，切莫等到出现故障再去更换冷却液。一般建议车辆每行驶4万公里或两年须更换新的冷却液，另外每两年须更换冷却风扇皮带。
However, it is difficult for us to judge whether the coolant is deteriorated by visual inspection, so we should replace the coolant regularly, and never replace the coolant until there is a fault. It is generally recommended that the vehicle should be replaced with new coolant every 40000 km or two years, and the cooling fan belt should be replaced every two years.
2.发动机点不着火。
2. The engine does not ignite.
病情原因：发动机的启动是靠电瓶的电流推动火花塞点火完成的，因而启动系统出现故障，很可能是由于电瓶生锈或者电瓶滴漏造成的。
Cause of illness: The engine is started by the spark plug ignited by the battery current, so the starting system fails, most likely due to the rust or leakage of the battery.
绿色保养：每一两个月要查看电瓶内的电瓶液是否充足。如果不足，可添加蒸馏水至适当的高度。
Green maintenance: check whether the battery liquid in the battery is sufficient every two months. If insufficient, add distilled water to the proper height.
目前轿车大都采用免维护电瓶，则不可擅自加水。此外，每年都要检查一下电瓶的正负端接点有无生锈或污浊的现象。
At present, most cars use maintenance free batteries, so it is not allowed to add water without authorization. In addition, check whether the positive and negative terminal points of the battery are rusty or dirty every year.
如果有，要及时到4S店清除干净，以保持电路的畅通。电瓶修复后，可延缓电瓶的报废时间，减少资源浪费和废弃电瓶对环境的污染。
If yes, go to the 4S store to clean it up in time to keep the circuit unblocked. After the battery is repaired, the scrapping time of the battery can be delayed, and the waste of resources and the environmental pollution caused by the discarded battery can be reduced.
3.发动机排气的噪声增加，废气排放也超标。
3. The engine exhaust noise increases, and the exhaust emissions also exceed the standard.
病情原因：发动机的废气经高温发生氧化作用，很可能导致排气系统泄漏。
Cause of illness: The exhaust gas of the engine is oxidized at high temperature, which may lead to leakage of the exhaust system.
绿色保养：检查排气系统的管路、接口处（特别是消音器等）是否被废气腐蚀，接口垫有没有被冲坏。若发现排气系统泄漏应及时修理或更换泄漏的部件。
Green maintenance: check whether the pipelines and interfaces of the exhaust system (especially the muffler) are corroded by exhaust gas, and whether the interface gasket is damaged. If the exhaust system leaks, repair or replace the leaking parts in time.
每年检查一次不仅可以保证排气系统正常运转，更重要的是减少尾气中有害物质对环境的污染。
The annual inspection can not only ensure the normal operation of the exhaust system, but also reduce the environmental pollution caused by harmful substances in the exhaust.
