ZF 8AT’s case is said to be maintenance-free, and the manual says to check the bottom shell of the gearbox regularly to see if there is any oil leakage. 4S used to say that if you have passed 60,000 kilometers, when you speed up the collection of fuel, the box is not very smooth, so consider changing the gearbox oil when excluding other reasons for irregularity. The current 4S also said that 60, 000 kilometers had to be replaced, and finally made a compromise, simply changing for 100000 kilometers. The price of 4S is very expensive, about 4.5k, of course, 4S store people feed horses, expensive is understandable, do not go to more comments. Finally, the ball friend introduced a fixed-point repair Audi store for enterprises and institutions and went to it to replace it. The price is still very good, it is very difficult to earn money in recent years, so save it if you can.
The car in March 2015, which was bought in May that year, has now reached 98698 kilometers. The following is a change of oil and water accounting, interested riders can refer to ↑
Given 7 barrels of oil with a capacity of 1L per barrel ↑
On the front of a single barrel, the production date of the oil is OK, and it is quite new in October 2022. 180 yuan per liter, it should be different channels to get the goods, some places are more expensive ↑
The back of the single barrel is also suitable for a wide range of models. The lubricating oil looks simple, but with the technical content, we still need to work hard here, ↑.
There is a QR code on the back of the barrel, which can be scanned to determine whether it is true or false. I don’t think this factory will give you problematic oil. After all, a lot of Audi repair here, the boss has repaired cars for more than 20 years, and the credit still has to be ↑.
↑ on the back of the gearbox filter core
The positive view of the gearbox filter core, this side is facing the ↑ of the electromechanical control unit in the gearbox.
Seal ring, this must be changed, otherwise the periphery leakage ↑
These are aluminum screws for the bottom case of the gearbox and must also be replaced, because the twisted old ones can no longer be used with ↑
Q5 chassis, wrapped really tight, this is the gearbox bottom shell exposed after removing the protective shell ↑
After the gearbox chassis protection frame was removed, the box had to be propped up with a support bar, which should be two supports. At that time, a ↑ was taken.
The oil released is quite clear to the naked eye. Gearbox oil is different from engine oil, which blackens after being used for a period of time, but the clearness of gearbox oil does not prove that its quality remains the same ↑.
This is the famous electromechanical control unit. Automatic box, it is said to rely on oil to drive gear changes, in order to achieve the purpose of up and down gear. But how to change, when to change, and how to stir the oil pressure in the box to achieve the operation of up and down gear depends on this electromechanical control unit, ↑
This is the side of the replaced gearbox filter back to the electromechanical control unit, slimy ↑.
This is the side of the replaced gearbox filter facing the electromechanical control unit, there is still a lot of sludge and a strong sense of greasy ↑.
Fill the hydraulic press with new gearbox oil ↑
Use the press to fill the gearbox with ↑
Six barrels of 6L oil were used, and there was one barrel left. How to judge whether there is enough gas? After adding, start the engine, shift, let the oil pressure stir in place, do not flameout and then put the gearbox oil, if there is an overflow, prove that the filling is enough, there is no overflow, you have to replenish the ↑
The factory works well. When putting up the chassis support of the box, after twisting the screws, seal the screw ↑ with a marker pen.
Even the front guard plate was sealed with a paint pen after it was twisted, but it was still very serious ↑.
From dismantling to changing, it takes nearly 90 minutes, the whole process, the small master workers are very serious, less than 100000 kilometers to change the transmission oil, and then open 60, 000 or 80, 000. After all, a car is a means of transportation, so you don’t have to spoil it too much, but you have to love it. You know something about it, and you just have to maintain it regularly. Q5 is basically going to drive, at present, there is no so-called burning engine oil, the operation is stable, the fuel consumption is OK, the power is enough, and running at high speed is very powerful. There is no special feeling after changing the gearbox oil, but the acceleration is lighter and the up and down gear is a little more sensitive.
