1, 2 years: the warranty period, the first two years of the car is the peak, basically no problem. It's not true... Most cars have to replace their batteries within at least two years. Golf uses maintenance free batteries, which means the life of the battery starts to count down from the time the electrolyte is added to the battery, usually two years. Although there is a "observation window" battery, as long as it is green, it can continue to be used, but it also looks "green" rather than saying "hello" or "put down the car", and it doesn't need to worry too much. Generally, when the battery fails to appear again after you stop, it won't directly put you in the middle. The problem is, although the whole car has electricity (lights, sound, meters... ）, but the engine can't be started and the starter can't turn when the ignition is started. At this time, all the warning lights on the instrument panel flash! There's no need to panic. Because the current is not stable. They are not bad. You have no choice but to use another car's battery "hook" car directly to the garage for a new car.

　　此外，两年也是制动液强制更换的期限。制动液(也称为制动液)很容易吸湿油,如果有水进入油系统,刹车时产生的高温会使气化这水,当你踩刹车压缩只是这部分空气,和制动盘不能准确和有力的摩擦盘……

　　In addition, two years is also the period of compulsory replacement of brake fluid. Brake fluid (also known as brake fluid) is easy to absorb oil. If there is water entering the oil system, the high temperature generated during braking will vaporize the water. When you step on the brake to compress only this part of air, and the brake disc cannot accurately and powerfully rub the disc...

　　2、3年:更换刹车皮和燃油泵。对于那些喜欢大量使用机油，然后在关键时刻猛踩刹车的人来说，刹车会磨损很多，寿命很短。通常被称为“刹车盘/刹车片”，刹车片更常用在三轮车上。制动系统是汽车重要的部件之一，是汽车的“部件”。如果引擎坏了，你就不能走了;如果刹车坏了，你就有麻烦了。必须经常进行严格的检查。通常在使用中要注意前后车轮的磨损四个制动盘,表面是否光滑,如果某个制动盘有凹槽,立即修复和替换,制动盘是不合格的,刹车盘光“盘”,是打磨平,也重来取代。

　　2. 3 years: replace the brake skin and fuel pump. For those who like to use a lot of oil and then slam on the brake at a critical moment, the brake will wear a lot and have a short life. Usually referred to as "brake disc / pad", the brake pad is more commonly used on tricycles. Brake system is one of the most important parts of the car, and it is the "safety part" of the car. If the engine breaks down, you can't leave; if the brake breaks down, you're in trouble. Strict inspection must be carried out frequently. Usually in use, pay attention to the wear of the front and rear wheels. Check whether the surface of the four brake discs is smooth. If a brake disc has a groove, repair and replace it immediately. The brake disc is absolutely unqualified. The brake disc is polished and replaced again.

　　3、4年:汽车行驶时，可能会发现新车时那么平稳，如果遇到这种情况，是时候检查一下汽车的减震器了。如果减震器的弹簧不再有弹性，它会在高速下剧烈震动，尤其是在雨天。我的理解是减震器和弹簧是不同的东西。在汽车悬架系统中，汽车起重器的作用主要是支承弹簧和板簧，而减振器(减震器)实际上是吸收振动或冲击或抑制“减震结构”，是一个填满油的活塞缸。

　　3. 4 years: when driving, you may find that the new car is so stable. If you encounter this situation, it's time to check the shock absorber of the car. If the spring of the shock absorber is no longer elastic, it will vibrate violently at high speed, especially in rainy days. My understanding is that shock absorbers and springs are different things. In the automobile suspension system, the main function of the automobile crane is to support the spring and leaf spring, while the shock absorber (shock absorber) is actually to absorb the vibration or shock or to suppress the "shock absorption structure", which is a piston cylinder filled with oil.

　　说白了,如果弹簧和减震器坏了,的性能故障是非常典型的,不是高速驾驶在晃动,但“huoyou”,有点凹凸不平的地方,身体像小船在水中上下震动乱摇,弓和刮到地上完全没有之前的平静。另一方面，如果减震器没有坏，弹簧也坏了，汽车另一侧的重量就会直接落在减震器上，一直压到，运动就会很痛苦，就像骑在石头上一样。

　　Frankly speaking, if the spring and shock absorber are broken, the performance failure is very typical, not high-speed driving shaking, but "hooyou", a bit uneven place, the body is like a boat shaking up and down in the water, bow and scrape to the ground completely without the previous calm. On the other hand, if the shock absorber is not broken and the spring is broken, the weight on the other side of the car will fall directly on the shock absorber, until the end, the movement will be painful, just like riding on a stone.

　　事实上,检查减震器故障非常简单,用手在体内的四个角落,力压,如果释放后的手颤抖的身体反弹不是一个或两个以上,这是正常的,如果继续上下弓,它看起来很有弹性……会坏。

　　In fact, it's very simple to check the failure of the shock absorber. Use your hands at the four corners of the body and press. If the shaking body rebounds not one or more than two after release, it's normal. If you continue to bend up and down, it looks very elastic... It will be bad.

　　4、5年:对一般家庭用车情况，注意皮带的定时不更换。如果不及时更换，汽车就会在半路上突然坏掉，要付出更高的维修费用。更换正时皮带重要的参数是里程，而不是时间。建议在规定的行驶里程内稍微提前更换。

　　4. 5 years: for the general family car use, pay attention to the timing of the belt does not change. If it is not replaced in time, the car will suddenly break down on the way, which requires a higher maintenance cost. The most important parameter for replacing the timing belt is mileage, not time. It is recommended to replace it slightly in advance within the specified mileage.

　　5年后:很多人在这个时候换了一辆新车，毕竟5年后的车，会出现更多的问题。我不是，在这里解释这些问题并不容易。如果你的车已经用了5年以上，你想了解更多的保养信息，你可以亲自去问别人。

　　Five years later: many people change a new car at this time. After all, there will be more problems in the car five years later. I'm not an expert. It's not easy to explain these problems here. If your car has been in use for more than 5 years, and you want to know more about the maintenance, you can ask others in person.
