The automatic transmission of modern cars is a high-tech electronically controlled system. The design of the transmission consists of many parts that work under severe loads. To avoid unexpected breakdowns and maintain a long service life, regular maintenance should be carried out, as well as the use of a lubricant approved by the manufacturer.
A bit of theory: the 4-Motion system
At the Volkswagen Tiguan crossover, the torque from the motor is transmitted to an automatic gearbox. Further, the transfer case provides rotation of the front and rear axles. The movement is transmitted to the front wheels through the front axle differential. At the same time, torque is supplied through the cardan shaft to the Haldex all-wheel drive clutch, which drives the main gear and rear axle differential. Depending on the operating mode and driving conditions, the automation distributes the torque force along the axes, ensuring maximum efficiency.
Volkswagen Tiguan is equipped with a hydromechanical 6-speed automatic transmission with a planetary gear, which is characterized by simplicity of design, compactness and low weight. The automatic transmission is equipped with an adjustable torque converter lock-up clutch, as well as electro-hydraulic gear shifting drives. The box is equipped with an oil cooler to cool the lubricant while the vehicle is moving.
The rotation of the wheels of the rear axle is provided by the Haldex clutch, located in the rear final drive housing. Oil pressure on the piston compresses the friction discs and the clutch transmits torque up to 2400 Nm. An electric axial piston type pump, which is controlled by an electronic controller, is responsible for pumping oil. The working pressure in the hydraulic system of the Haldex coupling is about 29 atmospheres. The system is equipped with a maintenance-free oil filter with check valve.
Note! If the Haldex clutch pump fails, the oil pressure in the system disappears, and the transmission of torque to the rear wheels stops.
Transmission fluids for Volkswagen Tiguan
For automatic transmission AISIN 09M, the manufacturer recommends the use of working fluid ATF ( Automatictransmission fluid) G 055 025 standard. The grease has a high fluidity and a characteristic red color.
Those who like to save money on analogues should remember that, unlike standard gear oils 70W-80, 80W-90, in automatic transmissions, the lubricating fluid must remain fluid at any temperature up to 120 degrees. Therefore, the SAE viscosity classification does not apply to ATF fluids.
Automatic transmission capacity at the first factory filling is 7 liters. When replacing, about 5 liters of gear lubricant will be required, since the remaining 2 liters of oil are distributed along the lines, cooler cavities and the internal volume of the gearbox and cannot be drained without complete dismantling and disassembly of the assembly.
Haldex is poured into the all-wheel drive clutch mineral gear oil VAG G055 175 A2. The volume of the system is 720 ml.
Changing the oil in an automatic transmission
Many manuals indicate that the transmission oil in the Volkswagen Tiguan automatic transmission, filled in at the factory, retains its performance characteristics throughout the entire life of the car. However, in practice, it is recommended to replace the lubricant in the gearbox every 60 thousand kilometers due to the difficult operating conditions of the mechanism.
To change the oil in a Tiguan automatic transmission with your own hands, you will need the following consumables:
- transmission lubricant ATF of the appropriate approval;
- oil filter (code 09M 325 429);
- gearbox pan gasket (code 09M 321 370A);
- sealing ring of the drain plug (code 09D 321 181B);
- oil drain container;
- rag.
Also, for work, you will need a device for pumping transmission fluid.
For a successful replacement, the oil in the Tiguan automatic transmission must be warm. To do this, you need to travel for at least an hour in various modes. After warming up the lubricant, the car is installed on a viewing hole, overpass or hung out on a lift.
To access the gearbox, the engine protection and gearbox mudguard are removed. The box tray and adjacent surfaces are cleaned of dust and dirt. To drain the old gear lubricant, unscrew the drain plug with a No. 5 hex wrench.
Warning! Gear oil flows out of the gearbox opening in a spiral jet, so it is recommended to use a funnel of a suitable size to collect the oil to avoid spilling liquid and contaminating clothes and work area.
After about one liter of oil has drained, you need to unscrew the overflow pipe using a hexagon to ensure further leakage of lubricant.
When the transmission lubricant leak stops (the total volume of the drained fluid will be about 4 liters), the drain plug is put in place, and the bolts securing the automatic transmission pan are unscrewed with a 10 key.
Remains of grease are drained from the dismantled pan, the inner surface is carefully wiped dry with a rag, and metal particles resulting from wear of the box parts are removed from the magnets. Then the oil filter with a protective mesh is disconnected from the valve body.
Information! In most cases, automatic transmission breakdowns are not caused by a deterioration in the properties of the transmission lubricant, but by washing out solid metal particles into the box mechanism that were not removed from the pallet magnets in time.
A new filter and a pan with a fresh gasket are installed in a regular place. Before installation, it is recommended to pre-lubricate the oil filter seals and the pan gasket with gear oil.
Development of automatic transmission Tiguan after changing the lubricant
For uniform distribution of the lubricant throughout the volume of the box, it is necessary to ensure operation of the automatic transmission in all modes for several minutes. After this procedure, the ATF level should be checked.
The lubrication level check is performed using a laptop with pre-installed software, such as VCDS or VAG K.
On the device connected via the diagnostic connector, the menu is activated: "Automatic transmission" - "Measured values" - "Group 06".
Initial conditions are set according to the manual:
- ATF transmission oil temperature not more than 30 degrees;
- the machine is standing on a flat horizontal surface;
- the gear selector is in the "Park" position.
On a running car, when the ATF temperature indicator reaches a value in the range from 35 to 45 degrees, the oil level control plug in the automatic transmission is unscrewed. With a sufficient level of lubrication, about 300 grams of oil will drain from the bypass tube. After that, the control hole is twisted with a plug with a new sealing ring. If the gear lubricant does not flow out of the control hole, then topping up the oil in the gearbox is required.
After completion of the operation, the surfaces of the parts are cleaned of oil residues, and the connections are checked for leaks.
You can get a visual representation of the oil change process in a Volkswagen Tiguan automatic transmission from the following video:
Changing the oil in the Haldex all-wheel drive clutch
According to the recommendations of the VAG concern for the Haldex coupling, oil changes should be carried out in the range of 40,000-60,000 kilometers, depending on the frequency and intensity of use of the all-wheel drive. For machines with low annual mileage, it is recommended to change the lubricant in the clutch every 12 months.
4th generation Haldex
To independently replace the gear oil in the Volkswagen Tiguan all-wheel drive clutch, you will need the following tools and materials:
- container for draining liquid;
- set of wrenches;
- pliers;
- a medical syringe for 100 cubes and a flexible tube of a suitable diameter;
- new oil for the Haldex coupling;
- oil filter 31325173;
- rags;
- gloves and goggles.
Work is carried out on a flyover, a viewing hole or on a car lift. To carry out an oil change, the machine must be installed strictly horizontally.
To preheat the old oil to facilitate the draining process, you should operate the car in all-wheel drive mode. Before removing the used fluid from the coupling, unscrew the two fixing bolts, remove the fine filter cover, pull out the plastic gasket with pliers and dismantle the filter element.
Advice! You can briefly start and immediately turn off the engine so that the filter with the gasket is squeezed out of the seat by oil pressure.
Then the drain plug of the clutch is turned out, and the transmission fluid is drained by gravity into a suitable container.
After the procedure is completed, the plug is screwed back into the Haldex coupling housing, and a new filter, previously lubricated with oil, is installed in the seat.
Also need make sure that there are no damages on the sealing rings, which are on a plastic gasket. Failed seals are replaced with new ones to prevent oil leakage. The assembled gasket is inserted into the coupling.
New oil is poured into the Haldex coupling using a syringe. To do this, instead of a needle, a flexible tube is put on, which is inserted into the filler hole. The procedure is carried out until grease begins to flow out of the hole. After a sufficient amount of gear oil has been filled in, the filler plug is screwed in, and the clutch housing is wiped dry with a rag.
Then a test drive is made, after which you should turn off the engine and make sure there are no leaks from under the plugs of the Haldex coupling. After 10-15 minutes, you need to unscrew the filler plug to control the lubricant level. If the liquid flows out, then the level is sufficient. If necessary, gear lubricant is added to Haldex. After checking, the plug is put in place, oil leaks are removed with rags. This completes the procedure.
The procedure for changing the oil in the Haldex VW Tiguan clutch can be seen in the following video:
5th generation Haldex
The sequence of work on changing the oil in the fifth generation Haldex is similar to that described above with one exception. As a result of the current trend to reduce the dimensions and weight of automotive units, the control solenoid valve has been removed from the design of the all-wheel drive clutch. Respectively Haldex 5 does not have an oil filter fine cleaning. As a result, wear products (metal dust and chips) accumulate in the oil circulating through the hydraulic system and are highly likely to cause serious damage. Therefore, for a greater guarantee for the new model of clutches, the interval between transmission lubricant changes should be reduced by another several thousand kilometers.
One of the main maintenance procedures for a Volkswagen Tiguan car is an oil change. The service life of the power unit depends on the timely change of fluid.
Before starting the replacement, it is necessary to choose the right oil for the gearbox in the Volkswagen Tiguan. You can change the oil in the gearbox yourself, if you have the tools at hand and follow the recommendations of the car manufacturer.
What oil to choose for the Volkswagen Tiguan?
When choosing a lubricant for the gearbox, use the transmission mixture recommended by the manufacturer. The automotive manufacturer requires the use of fluids of at least GL-4 and GL-5 class in gearboxes and dispensers. In the gearbox of a Volkswagen Tiguan car, you should choose oil with a viscosity of 75W90, with a volume of 1.7 liters.
An oil change in Volkswagen Tiguan gearboxes occurs at a mileage of 50 thousand km. Before changing the lubricant, the condition of the fluid must be checked regularly.
The reasons for changing the lubricant are:
- Low level of lubrication;
- Changing the color of the oil;
- The presence of metal chips, dust and dirt in the liquid.
If any of the signs appear, it is necessary to start preparing for an oil change. Lubricant VAG G052145S2 75-w90 API GL-5 is poured into the front axle gearbox, in a volume of 1 liter. The rear axle will require VAG G052196A2 75-w85 LS or VAG G052145S2. For Volkswagen Tiguan, you can fill in Castrol SAF-XO 75w90 or Motul Gear 300.
Replacement process
The fluid change procedure begins with the preparation of the necessary tools and materials. Work must be done in special clothing. To replace the fluid, the following tools and supplies are needed:
- Rubber gloves and special clothing;
- New original liquid;
- Capacity for draining the waste product;
- A set of keys.
Changing the oil in the Tiguan rear gearbox must be carried out in compliance with safety regulations. It is necessary to change the mixture in the gearbox at the same time as changing the oil in the gearbox.
The oil change in the gearbox carried out on the Tiguan begins with the car warming up for 15 minutes. The machine, after warming up the engine, is installed on a viewing hole or a jack, after which work is performed to drain the used lubricant in the following sequence:
- Under the car, gradually unscrew the oil drain plug, after substituting a container for used grease;
- Inspect the oil drain plug. Clean the magnets located on the cork from metal chips and dust by washing thoroughly;
- After installing the magnets in place, wait until the grease is completely drained;
- Magnets and aluminum spacer can be replaced with new ones;
- Screw the plug into place using the key.
Draining of the old fluid at this stage is over. You can start pouring new oil into the rear and front axle gearboxes:
- Unscrew the filler plug and pour in new original oil with the appropriate parameters;
- When the liquid begins to flow out of the hole, you can be sure that the gearbox is completely filled;
- Tighten the plug tightly, checking the reliability of fastening of all connections;
- Check for leaks by tightening all plugs.
It is worth remembering that changing the fluid without changing the filter is a useless process, because a dirty filter stops the oil supply. After completing the entire process of replacing the fluid, the car is ready for further operation.
What happens to the machine if there is not enough oil in the gearbox?
One of the reasons for the failure of the gearbox is the lack of transmission fluid in it. When the lubrication level is low, the gear teeth overheat and wear many times faster. Insufficient fluid in the gearbox will cause it to break.
The clutch helps to properly distribute torque to the wheels of the car. It has an electric drive control and is located in the final drive housing. The clutch helps to lubricate the rubbing parts, reducing their wear.
Due to a lack of transmission fluid, the clutch may also fail. This will affect not only the quality of the movement of the car, but also the possibility of movement.
Therefore, the replacement of transmission lubricant in all transmission units of transfer cases, gearboxes, gearboxes and clutches, as well as timely monitoring of the fluid level, is the main condition for proper vehicle maintenance.
In this article, we will consider changing the Tiguan 2.0 oil with a gasoline engine.
The frequency of changing the oil in the Volkswagen Tiguan engine
The frequency of changing the oil in the Tiguan engine is regulated every 15,000 km., This is under normal vehicle operating conditions.
The lubricating properties of engine oil last up to 300 hours on average, after which the oil loses its properties and during operation can only harm engine parts.
If we make a calculation and take the average speed of a car per day in a city with a population of one million, we get: 25 km / h multiplied by 300 motor hours and we get the recommended oil change already at intervals of every 7500 km.
How often to fill in new oil in a Volkswagen Tiguan is up to you.
Necessary spare parts for oil change
To change the oil in a Tiguan, we need the following spare parts:
- Engine oil with the recommended specification, which can be found in the vehicle's instruction manual. In our case, this is oil with the vw 502.00 specification.
The filling volume of oil in the Volkswagen Tiguan 2.0 engine is 4.7 liters
- New oil filter whose catalog number is 06J 115 561 B
- New sump drain plug, part number N90813202
- A container for draining old oil and a funnel for filling new
- Oil filter puller.
Do-it-yourself oil change in a Tiguan engine.
After a slight warm-up of the engine, we install the car on a flat surface of the inspection hole, we drive onto a lift or podium.
For free access, remove the decorative cover from the engine and open the filler neck.
We unscrew the engine protection.
Having prepared a container for draining the old oil, we tear off the drain bolt and unscrew it, after substituting the container for draining. When performing this operation, you must be extremely careful not to burn your hands with oil.
While the rest of the engine oil is draining from the sump, unscrew the oil filter. It is recommended to use a puller in this case, its cost will not exceed the cost of the nerves spent if the oil filter is tightly screwed on.
Wipe dry the drain hole and tighten the new bolt. Many Volkswagen Tiguan owners know that the drain bolt is disposable and do not neglect to replace it.
When installing a new oil filter, we lubricate the gasket with oil, it is not necessary to fill it with oil, since the filter is installed vertically down and there is a possibility of spillage during installation.
We insert a funnel into the filler hole and pour new engine oil into the Tiguan engine a little above the average level.
In the reverse order, install the decorative engine cover and its protection.
We start the engine and wait for the red oil pressure lamp to go out. We turn off the engine and add oil to the required level.
At the same time, the recommendation is to look for smudges in the area of \u200b\u200bthe drain bolt of the pan and the oil filter.
If your car has a service interval, which is displayed on the instrument panel screen, then do not forget to reset it.
Owners of the popular Volkswagen Tiguan crossover often wonder how to properly change the gearbox oil in this car. This question is especially relevant for those who service the car on their own. In fact, this procedure does not require professional skills, since the entire process of changing the oil is carried out by improvised means. In this article, we will consider how to properly change the oil in the front and rear gearboxes of the Volkswagen Tiguan.
The official regulation for changing the oil in the front and rear gearboxes of the VW Tiguan is 40 thousand kilometers. Long before this run, it is very important to regularly check the condition of the fluid. The need to replace the fluid, in addition to the above reasons, is indicated by the following signs:
- insufficient oil level
- the oil changed color from light to dark brown
- during the oil level check, metal chips, dust and dirt were found.
The sequence of work when changing the oil in the front and rear gearbox VW Tiguan
- Preparatory phase - before maintenance, a short trip of 15 minutes must be made
- After making sure that the engine is well warmed up, the trip can be completed and the car can be placed on a lift. It can be a viewing hole or a jack with high wheel supports. The main thing is to ensure unhindered access to the bottom of the machine
- So the car is on a lift. We climb under the car, and find the oil drain plug. Unscrew it gradually. You don't need a tool for this. After removing the plug, the waste liquid will begin to flow out of the hole. With high mileage, the oil will most likely have a black color. In addition, it may contain a lot of dirt and metal chips. With high mileage, this is quite normal, which is the result of mechanical wear of the gearbox components.
- Wait for the final drain of the waste fluid. While the oil is flowing out, to speed up the process, we proceed to the next step.
- Carefully inspect the oil drain plug. There are magnets on the plug, which usually prevent metal chips, dust and dirt from getting inside the gearbox. In other words, the function of the magnet is to attract various harmful environmental influences that can harm the gearbox. However, if the magnet is contaminated, it is no longer able to perform the functions assigned to itself. Because of this, all the dirt will then accumulate in the gearbox itself. That is why timely oil changes are so important. So, the magnets on the cork can be washed and cleaned well, or new magnets can be put in. After making sure that the magnets are in proper condition, as well as the complete draining of the old liquid, we install the plug back into place. To do this, use a key with a moment of 50 N / m. Before installing the cork, it does not hurt to replace not only the magnet, but also the aluminum gasket
- The next step is to fill the new oil into the rear and front axle gearboxes. To do this, unscrew the filler plug, which is on the body of each of the gearboxes, and begin to pour in new fluid. Please note that it is recommended to use original oil with the appropriate parameters specified in the Volkswagen Tiguan manual.
- As soon as the liquid starts to flow out of the hole, this will mean the gearbox is 100% filled with oil. We close the plug tightly, and once again check the reliability of fastening of all screw connections, if necessary, tighten all plugs to avoid oil leaks.
- If there are no leaks, and the oil level is normal, the procedure is completed, and you can proceed to the further operation of the Volkswagen Tiguan.

The Haldex coupling of the Volkswagen Tiguan, according to the manufacturer, is eternal and does not require maintenance. We understand that there are no eternal units and liquids, everything has its time, this is especially true for transmission units - transfer cases, gearboxes, gearboxes and couplings, including Haldex. Elsa, of course, knows better, we completely trust the German magicians, but no one has canceled the saying “Trust, but verify”.

The Haldex clutch was invented in 1988 by Swedish engineer Sigvard Johansson, who developed the idea of automatically redistributing torque between the axles of a car in unpredictable rally conditions, since he was also a rally racer. In 1992, he sold his invention to the Swedish company Haldex, after which they began to introduce it into the design of the Quattro all-wheel drive transmission, thereby realizing the concept of an automatically connected all-wheel drive. The Haldex coupling has been used in serial machines since 1998. The first were the Audi A3 Quattro, Audi TT and VW Golf.
The Haldex coupling of the Volkswagen Tiguan has been modified and adapted by German engineers. Before it, a viscous coupling was used, which gave all-wheel drive, but had a number of limitations and inconveniences, the main of which was a low response speed, which allowed the wheels to slip when the driver did not expect it. Haldex is controlled by a computer that monitors the speed of each wheel, cornering, how the car brakes and accelerates, takes data from the yaw sensor, based on which it controls the clutch. All this is perfectly combined with ABS, EDS, ESR, ASR, which allows us to drive comfortably and safely.
The hub, discs, working and sliding pistons rub, crush, compress each other, which means there will be wear. The Haldex clutch of the Volkswagen Tiguan is equipped with a filter that is installed in the rear axle gearbox housing and is activated when the all-wheel drive is turned on. VAG engineers somehow missed the logical chain “If there is a filter, then there is dirt”, and therefore it must be changed. The formula for the frequency of changing the oil in the Tiguan gearbox has long been derived - every 50 thousand kilometers with unloaded driving. Why is that? During the operation of the rear axle, wear products (metal, plastic, paper) get into the oil and, like the Chinese, who undermine all markets in the world, these abrasive particles undermine the operation of the rear gearbox. The contact of oil with metal provokes oxidation in this unit, which eventually results in more serious malfunctions, up to turning the car into a front-wheel drive - it's like getting a snowball in the face from a small child, it seems to be a trifle, but a bruise can be impressive.
Let's get started: first, the diagnostics of the Tiguan, then we drive the car through a technical wash, lift the needy on the lift, inspect the bottom and suspension for damage, smudges and some suspicious things. We make sure that everything is fine and proceed directly to the replacement.
The filter is hidden behind a cover.
It is not difficult to remove it, first you need to loosen the bolts on it, but do not unscrew them entirely.
The bolts are loose, the scanner is connected, - Wow! - we turn on the four-wheel drive with one movement of the finger and the cover is gently squeezed out by pressure from the gearbox. Fast, clean, neat! We move on.
We pass to the bolt in the drain hole. We unscrew it and get rid of the old oil with unwanted impurities. We are waiting for the gravity flow to stop: the oil will flow both from the drain plug and from the hole where the filter is located.
Now you can safely unscrew the bolts, remove the cover and pull out the filter.
This is how a filter with a burden of 53,000 kilometers looks like in close-up. There are indeed wear particles in the oil.
We install a new filter in its place and close the lid.
To get a guaranteed result from the procedure, we use only the original oil from the manufacturer. We share the serial number of the oil, we do not mind.
