寶馬汽車時間長了可能會出現一些不良反應，作為車主的您這個時候就要及時進行處理解決，不要讓小問題拖變為大問題，下面
濟南哪里有寶馬汽車維修的小編講三個問題。
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.車下滴漏出一攤莫名其妙的液體，且冷卻液的液面高度下降。
1. A pool of inexplicable liquid drips out under the car, and the level of coolant drops.
病情原因：通常情況下造成滴漏的原因是連接冷卻液箱和發動機間的橡皮管有裂縫。綠色保養：變質的冷卻液防銹品質下降，不但容易導致散熱器、管路、軟管等部件的損壞，而且因冷卻液的主要成分是乙二醇，滴漏到地上也會造成環境和空氣污染。
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.
但我們很難通過目測判斷冷卻液是否變質，所以要定期更換冷卻液，切莫等到出現故障再去更換冷卻液。一般建議車輛每行駛4萬公里或兩年須更換新的冷卻液，另外每兩年須更換冷卻風扇皮帶。
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.發動機點不著火。
2. The engine does not ignite.
病情原因：發動機的啟動是靠電瓶的電流推動火花塞點火完成的，因而啟動系統出現故障，很可能是由于電瓶生銹或者電瓶滴漏造成的。
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.
綠色保養：每一兩個月要查看電瓶內的電瓶液是否充足。如果不足，可添加蒸餾水至適當的高度。
Green maintenance: check whether the battery liquid in the battery is sufficient every two months. If insufficient, add distilled water to the proper height.
目前轎車大都采用免維護電瓶，則不可擅自加水。此外，每年都要檢查一下電瓶的正負端接點有無生銹或污濁的現象。
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，要及時到4S店清除干凈，以保持電路的暢通。電瓶修復后，可延緩電瓶的報廢時間，減少資源浪費和廢棄電瓶對環境的污染。
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.發動機排氣的噪聲增加，廢氣排放也超標。
3. The engine exhaust noise increases, and the exhaust emissions also exceed the standard.
病情原因：發動機的廢氣經高溫發生氧化作用，很可能導致排氣系統泄漏。
Cause of illness: The exhaust gas of the engine is oxidized at high temperature, which may lead to leakage of the exhaust system.
綠色保養：檢查排氣系統的管路、接口處（特別是消音器等）是否被廢氣腐蝕，接口墊有沒有被沖壞。若發現排氣系統泄漏應及時修理或更換泄漏的部件。
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.
每年檢查一次不僅可以保證排氣系統正常運轉，更重要的是減少尾氣中有害物質對環境的污染。
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.
