轮胎扎钉
Tire tie nails
问题：轮胎扎钉后，不严重的情况，通过补胎可以解决。但是维修人员却要求换轮胎。
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.
内幕：因为很多店不承接补胎业务，因此，他们会以没法补为由，直接让您换轮胎，价格就高了。
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.
识破办法：以下这几种情况，才建议您换胎
Detection method: It is recommended to change the tire in the following situations
①轮胎老化严重的。
① Tires are severely aged.
②轮胎上的花纹严重磨损，深度小于1.6mm。
② The pattern on the tire is severely worn, with a depth of less than 1.6mm.
③轮胎有严重鼓包，或者侧面扎钉。
③ The tire has severe bulging or side punctures.
④轮胎修补次数大于等于3次。

安全气囊故障灯
Airbag fault light
问题：气囊故障灯亮起，维修工建议换气囊，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.
内幕：气囊的构造并不是很简单，有很多的线束，如果挨个检查，不仅没有工时费，而且比较麻烦。维修人员为了省事，要求换掉气囊电脑。这一下就多几百甚至几千元。
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.
识破办法：还是告诉大家几个方法：
How to detect: Let me tell you a few methods:
①线束插头松，紧一下就行，要求维修人员检查。
① The wiring harness plug is loose, just tighten it a bit, and require maintenance personnel to inspect it.
②检查一下传感器是否有被触碰到，如果碰到了，属于假故障。
② Check if the sensor has been touched, if so, it is a false fault.
③气囊电脑故障，可以换。
③ The airbag computer is faulty and can be replaced.

烧机油
Burn engine oil
问题：很多时候，气门油封漏油才是导致烧机油的主要原因。
Problem: Often, valve oil seal leakage is the main cause of engine oil burning.
但是维修工却和您说是活塞环坏了，发动机需要大修。几百块钱能解决的问题，要4-5千才能解决，有时候，工时费就4-5千，其他的加起来更贵。
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.
内幕：其实出现烧机油这种情况，有很多的原因，气门油封、活塞环有故障都有可能，但是这其中，活塞环的利润是大的。因此，很多维修工先换活塞环，钱到手以后，再顺手换掉气门油封，问题解决了，钱也挣到了。
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.
识破办法：别在一个地方检查，如果一个地方说发动机需要大修，换个维修店再看看，如果有熟人好，因为我们自己很难辨别故障所在。
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.
