1. Pre fault symptoms: there is a strong sense of frustration when starting from 1 to 2, as well as downshifting. I didn't care at that time, because I had this feeling all the time in the first half of this year, but it gradually strengthened.

2、故障現(xiàn)象：在環(huán)線上導(dǎo)航時(shí)突然降到D3,且雪地和運(yùn)動(dòng)模式不停閃爍，SERVICE燈報(bào)警。停車熄火，再上電后也有報(bào)警顯示變速箱故障，但2秒后消失。繼續(xù)行走，加速到60碼以上上述現(xiàn)象再次出現(xiàn)。一路上一直采用上述方法重復(fù)了3次停車熄火。以后干脆讓它報(bào)警，變速箱鎖定到D3，不超過(guò)60碼開到4S店。

2. Fault phenomenon: when navigating on the loop line, it suddenly drops to D3, and the snow and movement mode keep flashing, and the service light gives an alarm. Stop the engine and turn on the power, there will be an alarm to show the gearbox fault, but it will disappear after 2 seconds. Continue to walk, accelerate to more than 60 yards, the above phenomenon appears again. The above method has been used for three times to stop the engine. In the future, simply let it alarm, lock the gearbox to D3, and drive to the 4S store within 60 yards.

3、送4s處理：4s店顯然熟悉該故障情況，我只是提到可能是電磁閥原因，檢修人員通過(guò)電腦聯(lián)機(jī)簡(jiǎn)單檢測(cè)后為壓力調(diào)節(jié)故障?，F(xiàn)場(chǎng)判斷為主油壓電磁閥問(wèn)題。當(dāng)時(shí)詢問(wèn)4S是否是保修，因?yàn)槲艺囐|(zhì)保2年已過(guò)期。不置可否，只是說(shuō)要到上面請(qǐng)示。

3. Send to 4S for treatment: the 4S store is obviously familiar with the fault, I just mentioned that it may be the cause of the solenoid valve, and the maintenance personnel simply detected the pressure regulation fault through the computer online. The main oil pressure solenoid valve was judged on site. At that time, I asked the 4S whether it was a warranty, because the warranty of my whole car had expired for two years. I'm not sure. I just want to go up there and ask for instructions.

過(guò)會(huì)兒請(qǐng)示結(jié)果下來(lái)，表示免費(fèi)更換，但是要求3萬(wàn)大保養(yǎng)順便在他那里做了。我當(dāng)即表示沒(méi)有問(wèn)題，因?yàn)槲冶緛?lái)就是準(zhǔn)備要做了，而且在淘寶上三濾，火花塞都買好了放車上，并且當(dāng)即在4s購(gòu)買了total7000機(jī)油。

After a while, I asked for the result and said that it would be replaced free of charge, but I asked for 30000 major maintenance, and I did it at his place by the way. I immediately said that there was no problem, because I was ready to do it, and I bought three filters and spark plugs on Taobao and put them on the car, and I immediately bought total7000 engine oil in 4S.

4、排除：你們應(yīng)該看到前面文字中的紅色字體了吧，問(wèn)題就出在這里，液力控制板(也叫油路板)更換電磁閥后再安裝上去后就出現(xiàn)噪音大。感謝4s店的師傅盡責(zé)盡力，更換后檢查到了這個(gè)板子問(wèn)題，可能是與電磁閥不匹配，也可能是板子還有其他故障沒(méi)有檢查到。

4. Troubleshooting: you should see the red font in the front text. The problem is that the hydraulic control board (also called oil circuit board) is noisy after replacing the solenoid valve and then installing it. Thanks to the master of the 4S shop, he did his best. After the replacement, he found the problem of the board. It may be that it does not match the solenoid valve, or it may be that the board still has other faults.
