汽車故障診斷指的是當(dāng)汽車存在故障隱患,技術(shù)狀況變差,或是已經(jīng)部分或完全喪失工作能力,在不解體(或僅卸下個別小件)條件下,為確定汽車技術(shù)狀況或查明故障部位、原因進(jìn)行的檢測,以及分析與判斷。下面來講講
濟(jì)南奧迪汽車維修常見的八種故障現(xiàn)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
機(jī)油泄漏已成為奧迪上的常態(tài)，有些車型甚還未過保修期就已經(jīng)開始漏油。泄漏位置完全沒有規(guī)則，氣門室蓋、機(jī)油濾芯底座、曲軸后油封和正時殼體都是主要的泄漏點之一。解決方案：塑料材料附件基本上都要更換總成，有些零件可以單獨密封。
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、門鎖塊
2. Door lock block
車越急，門開不開也鎖不上，然后問是不是尷尬。特別是部分車型在5年多的時間里，門鎖模塊開始逐漸出現(xiàn)問題。解決方案：市場上已經(jīng)可以更換門鎖模塊內(nèi)部電機(jī)，只需幾十件，不再受原廠限制，花1000多元更換門鎖模塊總成。
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
熟悉奧迪的朋友熟悉此故障，MMI多媒體翻轉(zhuǎn)屏幕黑屏故障時有發(fā)生。主要有兩個原因：一是翻轉(zhuǎn)屏內(nèi)部電纜老化；二是J794主機(jī)內(nèi)部電路問題。解決方案：這兩種故障都可以修復(fù)，他們都是電路問題，維修很容易。
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、燃燒機(jī)油
4. Combustion oil
恐怕奧迪燃燒機(jī)油的問題除了外星人以外，其他人都不知道。然而與寶馬不同的是，奧迪因氣門油封問題而燃燒機(jī)油的案例很少，其中大部分是由活塞環(huán)或油氣分離器引起的。解決方案：更換油氣分離器，活塞環(huán)只能發(fā)動機(jī)大修，維修費用高昂。之前，在汽車售后市場上，有一種不解體的燃油燃燒處理方式，效果因車而異。
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、手臂損傷
5. Arm injury
汽車臂是底盤懸掛系統(tǒng)的重要組成部分，他彈性地連接車身和車輛，車輛行駛時，下臂將車軸與車架彈性連接，以減緩汽車行駛過程中路面產(chǎn)生的沖擊（力），從而保證舒適性行駛。如果橡膠蓋損壞，路面會發(fā)出叮當(dāng)聲和叮當(dāng)聲，當(dāng)方向被擊中時會發(fā)出吱吱聲。解決方案：檢查并更換臂橡膠套或臂。
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、半軸籠
6. Half shaft cage
懸架系統(tǒng)惡劣的工作環(huán)境對零部件的使用壽命是一個很大的考驗，但是，球籠蓋的橡膠材料不能持久，半軸球籠蓋先掉下來。解決方案：籠蓋可以單獨更換，維護(hù)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
大眾汽車的車主們已經(jīng)感受到了這個問題，畢竟在早期，這個問題在EA888引擎中更常見，現(xiàn)在連大排量V6V8無法擺脫這個問題。雖然奧迪沒有像寶馬那樣使用電子水泵，但機(jī)械太愛確實泄漏了。解決方案：更換水泵。
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、膨脹罐漏水
8. Water leakage of expansion tank
如果泵的泄漏足以讓你頭疼，那么膨脹水箱就足以讓你跳舞了。奧迪似乎在膨脹箱（防凍劑準(zhǔn)備罐）上施了魔法，經(jīng)過幾年的漏水，仍然向外滴水，很難檢測到。解決方案：更換膨脹箱。
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.
