在我們用車過程中，車輛出了小的故障，我們把車開到修理廠或者4S店。如果遇到不良商家可能本來花幾十塊錢的問題，卻要上千元甚至上萬元。今天我們來盤點一些“小病大修”事項，以及
濟南沃爾沃汽車專修人員教您如何避免。

輪胎扎釘
Tire tie nails
問題：輪胎扎釘后，不嚴重的情況，通過補胎可以解決。但是維修人員卻要求換輪胎。
Problem: If the tire is not severely damaged after being punctured, it can be solved by repairing the tire. But the maintenance personnel requested a tire change.
內幕：因為很多店不承接補胎業務，因此，他們會以沒法補為由，直接讓您換輪胎，價格就高了。
Insider: Because many stores do not undertake tire repair business, they will directly ask you to change the tire on the grounds that it is not possible to repair it, which will increase the price.
識破辦法：以下這幾種情況，才建議您換胎
Detection method: It is recommended to change the tire in the following situations
①輪胎老化嚴重的。
① Tires are severely aged.
②輪胎上的花紋嚴重磨損，深度小于1.6mm。
② The pattern on the tire is severely worn, with a depth of less than 1.6mm.
③輪胎有嚴重鼓包，或者側面扎釘。
③ The tire has severe bulging or side punctures.
④輪胎修補次數大于等于3次。
④ The number of tire repairs is greater than or equal to 3.

安全氣囊故障燈
Airbag fault light
問題：氣囊故障燈亮起，維修工建議換氣囊，以及其配套的部件。
Problem: The airbag fault light is on, and the repairman suggests replacing the airbag and its supporting components.
內幕：氣囊的構造并不是很簡單，有很多的線束，如果挨個檢查，不僅沒有工時費，而且比較麻煩。維修人員為了省事，要求換掉氣囊電腦。這一下就多幾百甚至幾千元。
Insider: The construction of airbags is not very simple, there are many wiring harnesses. If checked one by one, not only will there be no labor cost, but it will also be quite troublesome. The maintenance personnel requested to replace the airbag computer in order to save time. This adds hundreds or even thousands of yuan.
識破辦法：還是告訴大家幾個方法：
How to detect: Let me tell you a few methods:
①線束插頭松，緊一下就行，要求維修人員檢查。
① The wiring harness plug is loose, just tighten it a bit, and require maintenance personnel to inspect it.
②檢查一下傳感器是否有被觸碰到，如果碰到了，屬于假故障。
② Check if the sensor has been touched, if so, it is a false fault.
③氣囊電腦故障，可以換。
③ The airbag computer is faulty and can be replaced.

燒機油
Burn engine oil
問題：很多時候，氣門油封漏油才是導致燒機油的主要原因。
Problem: Often, valve oil seal leakage is the main cause of engine oil burning.
但是維修工卻和您說是活塞環壞了，發動機需要大修。幾百塊錢能解決的問題，要4-5千才能解決，有時候，工時費就4-5千，其他的加起來更貴。
But the repairman told you that the piston ring is broken and the engine needs to be overhauled. A problem that can be solved for a few hundred yuan takes 4-5000 yuan to solve. Sometimes, the labor cost is only 4-5000 yuan, and the rest are even more expensive.
內幕：其實出現燒機油這種情況，有很多的原因，氣門油封、活塞環有故障都有可能，但是這其中，活塞環的利潤是大的。因此，很多維修工先換活塞環，錢到手以后，再順手換掉氣門油封，問題解決了，錢也掙到了。
Inside story: In fact, there are many reasons for the occurrence of engine oil burning. It is possible for valve oil seals and piston rings to malfunction, but among them, the profit of piston rings is significant. Therefore, many maintenance workers first replace the piston rings, and after receiving the money, they easily replace the valve oil seals. The problem is solved, and the money is also earned.
識破辦法：別在一個地方檢查，如果一個地方說發動機需要大修，換個維修店再看看，如果有熟人好，因為我們自己很難辨別故障所在。
Detection method: Do not inspect in one place. If one place says that the engine needs major repairs, go to a repair shop and take a look. If there are good acquaintances, it is difficult for us to identify the fault ourselves.
