汽车故障诊断指的是当汽车存在故障隐患,技术状况变差,或是已经部分或完全丧失工作能力,在不解体(或仅卸下个别小件)条件下,为确定汽车技术状况或查明故障部位、原因进行的检测,以及分析与判断。下面来讲讲
济南奥迪汽车维修常见的八种故障现象吧。
Automobile fault diagnosis refers to the detection, analysis and judgment for the purpose of determining the technical condition of the automobile or finding out the fault position and cause without disassembling (or only removing individual small parts) when the automobile has hidden trouble, the technical condition is poor, or the working capacity has been partially or completely lost. Let's talk about eight common fault phenomena in Jinan Audi automobile maintenance.
1、漏油
1. Oil leakage
机油泄漏已成为奥迪上的常态，有些车型甚还未过保修期就已经开始漏油。泄漏位置完全没有规则，气门室盖、机油滤芯底座、曲轴后油封和正时壳体都是主要的泄漏点之一。解决方案：塑料材料附件基本上都要更换总成，有些零件可以单独密封。
Oil leakage has become a normal phenomenon on Audi. Some models have started to leak oil even before the warranty period has expired. The leakage position is completely irregular. Valve cover, oil filter element base, crankshaft rear oil seal and timing housing are all the main leakage points. Solution: plastic material accessories basically need to replace the assembly, and some parts can be sealed separately.
2、门锁块
2. Door lock block
车越急，门开不开也锁不上，然后问是不是尴尬。特别是部分车型在5年多的时间里，门锁模块开始逐渐出现问题。解决方案：市场上已经可以更换门锁模块内部电机，只需几十件，不再受原厂限制，花1000多元更换门锁模块总成。
The more urgent the car is, the door won't open or lock. Then I asked if it was embarrassing. In particular, the door lock module of some models began to have problems in more than 5 years. Solution: the internal motor of the door lock module can be replaced in the market, only a few dozen pieces are needed, and it is no longer limited by the original factory. It costs more than 1000 yuan to replace the door lock module assembly.
3、mmi黑屏
3. MMI black screen
熟悉奥迪的朋友熟悉此故障，MMI多媒体翻转屏幕黑屏故障时有发生。主要有两个原因：一是翻转屏内部电缆老化；二是J794主机内部电路问题。解决方案：这两种故障都可以修复，他们都是电路问题，维修很容易。
Friends familiar with Audi are familiar with this fault. MMI multimedia flip screen black screen fault occurs from time to time. There are two main reasons: first, the cable inside the flip screen is aging; The second is the internal circuit problem of j794 host. Solution: these two kinds of faults can be repaired. They are circuit problems, and maintenance is easy.
4、燃烧机油
4. Combustion oil
恐怕奥迪燃烧机油的问题除了外星人以外，其他人都不知道。然而与宝马不同的是，奥迪因气门油封问题而燃烧机油的案例很少，其中大部分是由活塞环或油气分离器引起的。解决方案：更换油气分离器，活塞环只能发动机大修，维修费用高昂。之前，在汽车售后市场上，有一种不解体的燃油燃烧处理方式，效果因车而异。
I'm afraid no one except aliens knows about the problem of burning oil in Audi. However, unlike BMW, there are few cases of Audi burning engine oil due to valve oil seal problems, most of which are caused by piston rings or oil-gas separators. Solution: replace the oil-gas separator, the piston ring can only be overhauled, and the maintenance cost is high. Previously, there was a non disassembly fuel combustion treatment method in the automobile after-sales market, and the effect varied from vehicle to vehicle.
5、手臂损伤
5. Arm injury
汽车臂是底盘悬挂系统的重要组成部分，他弹性地连接车身和车辆，车辆行驶时，下臂将车轴与车架弹性连接，以减缓汽车行驶过程中路面产生的冲击（力），从而保证舒适性行驶。如果橡胶盖损坏，路面会发出叮当声和叮当声，当方向被击中时会发出吱吱声。解决方案：检查并更换臂橡胶套或臂。
The automobile arm is an important part of the chassis suspension system. It elastically connects the body and the vehicle. When the vehicle is running, the lower arm elastically connects the axle and the frame to reduce the impact (force) generated by the road surface during the driving of the vehicle, so as to ensure comfortable driving. If the rubber cover is damaged, the road will make a jingle and a jingle, and when the direction is hit, it will make a squeak. Solution: check and replace the arm rubber sleeve or arm.
6、半轴笼
6. Half shaft cage
悬架系统恶劣的工作环境对零部件的使用寿命是一个很大的考验，但是，球笼盖的橡胶材料不能持久，半轴球笼盖先掉下来。解决方案：笼盖可以单独更换，维护成本很低。
The poor working environment of the suspension system is a great test for the service life of the parts. However, the rubber material of the ball cage cover cannot last, and the half axle ball cage cover falls off first. Solution: the cage cover can be replaced separately, and the maintenance cost is very low.
7、水泵泄漏
7. Water pump leakage
大众汽车的车主们已经感受到了这个问题，毕竟在早期，这个问题在EA888引擎中更常见，现在连大排量V6V8无法摆脱这个问题。虽然奥迪没有像宝马那样使用电子水泵，但机械太爱确实泄漏了。解决方案：更换水泵。
Volkswagen owners have already felt this problem. After all, in the early days, this problem was more common in EA888 engines. Now even large displacement v6v8 can not get rid of this problem. Although Audi doesn't use the electronic water pump as BMW does, the mechanical love does leak. Solution: replace the water pump.
8、膨胀罐漏水
8. Water leakage of expansion tank
如果泵的泄漏足以让你头疼，那么膨胀水箱就足以让你跳舞了。奥迪似乎在膨胀箱（防冻剂准备罐）上施了魔法，经过几年的漏水，仍然向外滴水，很难检测到。解决方案：更换膨胀箱。
If the pump leaks enough to give you a headache, the expansion tank is enough to make you dance. Audi seems to have magic on the expansion tank (antifreeze preparation tank). After several years of water leakage, it still drips out, which is difficult to detect. Solution: replace the expansion tank.
