Automatic transmission modern cars - This is a high-tech system with electronically control. The design of the transmission consists of a plurality of parts operating under serious loads. To eliminate unexpected breakdowns and maintain a long service life, you must regularly conduct maintenanceAnd also use the lubricant approved by the manufacturer.

A bit of theory: 4-motion system

Krossover Volkswagen Tiguan Torque from the motor is transmitted to an automatic speeds. Further, transfer case Provides rotation of the front and rear axles. The movement is transmitted to the front wheels through the front axle differential. simultaneously through cardan Val. The torque is fed to the couphe full drive Haldex, which drives the main gear and the rear axis differential. Depending on the mode of operation and conditions of movement, the automation distributes the torque over the axes, providing maximum efficiency.

Volkswagen Tiguan is equipped with a hydromechanical 6-speed automatic transmission with planetary mechanismFor which the simplicity of the device, compactness and a small mass are characteristic. The automatic transmission is equipped with an adjustable clutch of the torque converter blocking, as well as electro-hydraulic gear shift drives. The box is equipped with an oil cooler for the cooling of the lubricant during the movement of the car.

Rotation of the rear axle wheels provides Haldex coupling is placed back in the main transmission housing. The pressure of the oil on the piston leads to the compression of the friction discs, and the coupling transmits the torque to 2400 N * m. For injection of oil corresponds to an axial-piston-type electric pump, which is controlled by an electronic controller. The working pressure in the Haldex coupling hydraulic system is about 29 atmospheres. The system is equipped with a non-affordable oil filter with check valve.

Note! When the Haldex clutch pump fails, the oil pressure in the system disappears, and the transmission of torque to the rear wheels is stopped.

Transmission fluids for Volkswagen Tiguan

For automatic box aISIN gear 09m manufacturer recommended use working fluid ATF ( Automatic. TRANSMISSION FLUID) Standard G 055 025. Lubrication has high yield and characteristic red.

Fans to save on analogues should be remembered that, unlike standard transmission oils 70W-80, 80W-90 in automatic transmission, lubrication fluid should remain fluid at any temperature up to 120 degrees. Therefore SAE viscosity classification to liquids ATF. Not applicable.

The capacitance of automatic transmission at the first factory fill is 7 liters. When replacing the replacement, about 5 liters of transmission lubricant will be required, since the remaining 2 liters of oils are distributed through highways, cavities of the cooler and the inner volume of the checkpoint and are not subject to a plum without fully dismantling and disassembling the node.

Haldex full drive coupling is poured mineral transmission vag oil G055 175 A2. The volume of the system is 720 ml.

Changing the oil in an automatic transmission

In many manuals it is indicated that the transmission oil into Volkswagen Tiguan automatic transmission, stressed in the factory conditions, retains its performance features During the entire service life of the car. However, in practice it is recommended to replace the lubricant in the gearbox every 60,000 kilometers of the path passed due to the difficult conditions of the mechanism.

To replace the oil in the Tiguan automatic transmission, with their own hands, the following will be required. consumables:

• transmission lubricant ATF appropriate tolerance;
• oil filter (code 09m 325 429);
• pCP pallet gasket (code 09m 321 370A);
• sealing ring plug plug (code 09D 321 181B);
• capacity for draining oil;
• rag.

Also, for the work it will need an injection of transmission fluid.

For successful replacement, oil in the Tiguana automatic transmission must be heated. To do this, you need to ride at least an hour in various modes. After heating the lubricant, the car is installed on the observation pit, the overpass or hangs on the lift.

For access to the speeds of the speed, the engine protection and the sprinkler of the checkpoint is removed. Pallet boxes and adjacent surfaces are cleaned of dust and dirt. To drain the old transmission lubrication, you need to unscrew the six-sided key No. 5 drain plug.

A warning! The transmission oil flows out of the opening of the gearbox with a spiral jet, so it is recommended to use the funnel of the appropriate size to collect the oil to avoid fluid spills and pollution of clothing and the working area.

After about one liter of oil is alive, you need to unscrew the overflow tube using a hexagon to ensure further lubrication.

When flow stops transmission lubricant (total volume of fluid fusion of about 4 liters), drain plug is set in place, and the key 10 are unscrewed bolts automatic pallet.

From the dismantled pallet, the residues of the lubricant merge, the inner surface is thoroughly wiping with rags dry, and metal particles resulting from the wear of the box parts are removed from magnets. Then the oil filter with a protective mesh is disconnected from the hydroblock.

Information! In most cases, the automatic transmission failures are caused by no deterioration in the properties of the transmission lubrication, but washing into the mechanism of the metal particles of metal, which were not removed from the pallet magnets.

A new filter and pallet with fresh gasket are installed on the regular place. Before installing, it is recommended to pre-mark the oil filter seal and the pallet laying with transmission oil.

Development of automatic transmission Tiguan after replacing lubrication

For uniform distribution lubricant throughout the volume boxes must be provided functioning of automatic transmission on all modes within a few minutes. After this procedure, you should check the level of the transmission fluid ATF.

Checking the lubrication level is performed using a laptop with pre-installed software, for example, VCDS or VAG K.

On the device connected via the diagnostic connector, the menu is activated: "Automatic transmission" - "measured values" - "Group 06".

Source conditions are exhibited in accordance with the management:

• temperature transmission oil ATF. no more than 30 degrees;
• the machine stands on a flat horizontal surface;
• the transmission selector is in the "Parking".

On the engine, when an indicator "ATF temperature" reaches the values \u200b\u200branging from 35 to 45 degrees, the control plug of the oil level in the automatic transmission is twisted. With a sufficient level of lubrication from the bypass tube, about 300 grams of oil will merge. After that, the control opening is twisted with a plug with a new sealing ring. If the transmission lubricant does not follow from the control opening, then the oil topping is required in the speed box.

After the operation is completed, the surface surfaces are cleaned of oil residues, and the compounds are checked for leaks.

Get a visual idea of \u200b\u200bthe process of replacing the oil in Volkswagen Tiguan automatic transmission from the following video:

Replacing oil in the full drive Haldex coupling

According to the recommendations of the VAG concern for Haldex coupling, the oil replacement should be carried out in the range of 40,000-60,000 kilometers through the path, depending on the frequency and intensity of the use of the full drive. For cars with a small annual mileage, it is recommended to change lubricant in the coupling every 12 months.

4 generation Haldex

For user replaceable transmission Oil In the coupling of the full drive Volkswagen Tiguan, the following tools and materials will be required:

• capacity for draining liquid;
• set of wrenches;
• pliers;
• medical syringe for 100 cubes and flexible tube of suitable diameter;
• new oil for Haldex coupling;
• oil cleaning filter 31325173;
• rag;
• gloves and safety glasses.

Works are performed on the overpass, the observation pit or on the automotive lift. To replace the oil, the machine must be installed strictly horizontally.

To pre-warm the old oil to facilitate the drain process, you should exploit the car in the full drive mode. Perfectly removing the spent fluid from the coupling you need to unscrew two locking bolts, remove the filter cover thin cleaningUsing pliers to pull the plastic spacer and remove the filter element.

Tip! You can briefly start and immediately drown out the engine so that the oil filter with the gasket is squeezed out of the landing place.

Then the drain plug of the coupling is turned out, and transmission fluid Self merges in the appropriate capacity.

After the procedure is completed, the plug screws back into the Haldex clutch housing, and a new filter is installed in the landing space, pre-lubricated with oil.

Also need make sure that there are no damages on sealing rings, Which are on a plastic laying. Fatty seals are changed to new to eliminate oil leakage. The collected gasket is inserted into the coupling.

The new oil is poured into a Haldex coupling via syringe. To do this, instead of a needle, a flexible tube is put on, which is introduced into the bay hole. The procedure is performed until the lubricant will flow out of the hole. After a sufficient amount of transmission oil is flooded, the filler plug screws up, and the coupling housing is wiping dry with a rag.

Then a trial trip is made, after which the engine should be dried and make sure that there are no leaks from under the CHALDEX couplings. After 10-15 minutes you need to unscrew bay cork To control the lubrication level. If the fluid flows, the level is sufficient. If necessary, the transmission lubricant fills in Haldex. After checking, the plug is installed in place, oil drips are removed by rag. This procedure completed.

Oil replacement procedure in Haldex VW Tiguan coupling can be seen on the following video:

5 generation Haldex

The sequence of works on the replacement of oil in the Haldex of the fifth generation is similar to those described above in one exception. As a result, the current trend to reduce the size and weight of automotive design units wheel drive clutch control solenoid valve removed. Respectively Haldex 5 has no oil filter Thin cleaning. As a result, wear products (metal dust and chips) are accumulated in oil circulating through the hydraulic system, and with a high probability can lead to a serious breakage. Consequently, for a greater guarantee, a new clutch model interval between the replacements of transmission lubrication should be reduced by several thousand kilometers.

Before starting work, it is thoroughly cleaned from dirt all the places of engine connections and filter (so that the dirt inside did not get);
- The first to shoot the filter, it is desirable by the "extrusion" by the motor with a motor (through the lace / start the engine / direct feeding 12V on the terminals of the motor "+" from the square side of its chips, and the polarity change does not hurt) in order to avoid damage to the compactor with 2 rubber rings;
- Remember - which side was the filter !!! Because It has a check valve !!!;
- after draining the oil through the drain hole, 30Nm torque tube
- remove the motor (not breaking the chip of its connection to the block. You can practice on the chip from the tank of antifreeze - they are the same), clean the mesh on it;
- Consider the bank of the brake cleaner (better on an alcohol basis! In no case do not apply bd shki, carburetrators, etc. - they energize the rubber parts of the coupling) - splashing into the dump hole, holes available in the "bed" for the filter And for the motor, trying to clean the channels. As long as he will not be poured out of the same color you poured it there;

Put the correct side of the filter, lubricate the sealing stopper with oil and the tube itself with 2 rubber rings. And, not allowing her skewing gently to flush to the disappearance of the second remedies, attract the lid;
- the same thing to do and with the motor - lubricate the engine mount of the motor and the 2 of its sealing rubber rings themselves, put in place, tighten the moment 6nm (do not forget to put the chip back to the block);
- Pour a new oil ... The filling volume of the coupling of ~ 720 ml, immediately climbs only 600 ml. Because the Gulf oil on the edge of the filler hole, it (the hole) must be closed, drive smoothly 100-300 meters (if there is no possibility to take a ride, you can start the car a couple of times to bleed the system or start the pump Vasya), then add oil in the clutch again - like fit Once the rest is about ~ 120 ml ... Tightening torque 15 nm.
When checking the temperature, the oil temperature should be within 20 ... 40 ° C degrees Celsius.

Spin everything, tighten and rejoice)

Car with Haldex coupling due to the fact that the coupling is in one case with main TransferFrequently confused by the drain and filling corks of both systems.

You should avoid similar errors when maintenance and repair, because they can lead to the failure of the coupling or the main transmission.

In the article, we consider how the oil is replaced in the Haldex Volvo HS90 coupling. As a review, 4 generation coupling is provided.

The design feature is that the filter is located at the top unlike the 3 generation, in which it is located on the left side. In 5 generation there is no filter.

Considered an oil change is not suitable for 3 generations, since The pump can not be removed without removing the cardan.

Stepped oil replacement in Haldex Volvo HS90 coupling

We establish a car on a flat surface, for convenience to the observation pit or lift.

Turn off the terminals of the Haldex control module and unscrew it.

We unscrew the pump cover, which will help pull out without dismantling the cardan and unscrew the pump itself.

When removing, substitute the oil drain container.

When the remains of oil merge, proceed to the cleaning and defects of the pump of the coupling pump.

Dividing the motor and the case check the condition of the brushes and cleaned the inner dirt by the cleaner. Also remove the pump mesh and clean the dirt.

After washing, we leave the items to succumb and go to replace the filter.

With the approach of oil replacement in the Haldex clutch clutch with the installed cardan, it becomes difficult to turn off the filter bolts.

The bolts are located at the top and will have to be bothering the bolts to unscrew.

After the filter fastening bolts are unscrewed, remove the Haldex clutch filter cover. To do this, it can be pushed with a flat screwdriver.

Under the lid installed a plug that is subject to replacement. The cover is located in a hard-to-reach place and you can use a sharp heated object to remove, so that the cover goes into and pulling or eased at the end of the sewer. The new plug is supplied in Remkomplekt.

Filter mounted under the cap is removed and replaced with a new one. Before installing a new oil filter Couplings Recommended to lubricate clean oil And install to a characteristic click.

Also lubricate the new plug seal and screw to the regular place.

In order for the pump freely installed in place his back cover can be a little applied. This will allow you to immediately spin the pump housing and it will not be cling to the cardan floss.

We install the coupling control module and connect the connectors.

We unscrew the bolt of the filling opening, which also serves as an oil level.

Pour oil until it flows and tighten temporarily with an old washer.

Remove the car with the lift or come from a viewing hole and pass away like around the house or car service.

This procedure is necessary that the oil filled the filter and the pump is completely.

Re-install the car on a flat surface, for this suitable looking Yama, and unscrew the cork of the huldex coupling hole.

Take oil until the oil becomes a flow.

From the filled coupling with a new oil, we pump 40 ml., For example, using a syringe and it will be the correct level.

Tighten the cork-bolt with the use of a new washer.

It is so very simple as it turns out to be a replacement of oil in the Haldex Volvo Hs90 coupling.

3. Instruction:

From Elsa: vehicles with Haldex coupling due to the fact that the clutch is in one body with the main gear, often confused between a drain plugs and plugs for both systems. As a result of these errors, which, when maintaining and repairing, can avoid, can fail the coupling or main transmission.

1 - Threaded Cork Filling Haldex Coupling Cup.
2 - Drain Cup of Haldex Coupling.
3 - Threaded plug of the filling opening of the main transmission.
4 is a drain plug of the main transmission.

To clean the grid, the pump itself is not recommended, they are advised to clean it (grid) straight on it, by blowing and / or a brake cleaner on an alcohol basis. And if you decide to disassemble, then do everything very carefully, because There are springs and bearing. Be sure to write down or taking pictures as everything was to back assembly Do not get confused.

When you pulled the pump you will see a mesh on an iron round plate with a slot under the grid, unscrew only two bolts that keep the mesh third bolt in no case unscrew. The metallic plate is the mechanism of hydraulic pump that consists of a certain number of small parts, and as practice shows these parts, they will become lost or somewhat rolling. "It's enough just to pull it together with metal bushings. White mesh rinse it and put it back unforgettable change the set of gaskets them. Two, (0ay 598 305 - a set of seals for the pumping pump) The pump can not be disconnected from the power connector.

Sequence of work:

1. Carefully clean from dirt places all motor connections and the filter (that has not got into the mud). For example, use a brake cleaner on an alcohol basis.

2. Remove the filter:
2.1 We unscrew the bolts that are fastening the filter cover, remove the lid;
2.2 So that the filter moves from the landing opening is necessary:
· or Using a diagnostic lace: We connect "Vasya Diagnost", run 22 block "Full Drive System" Next 03 "Test Executive Mechanisms". Click to run. Tests are performed consistently. We reach the test "Running Motor Enabled" and click "Run".
· or By disconnecting the "chip" of the pump at the place of its connection to the coupling control unit, to use 12V on it from a conventional battery.

Careful with the pump chip, many from ignorance of how to shoot it - breaking the latch chips. To properly disconnect the connector, you can practice on the chip from the tank of antifreeze - they are the same (click on the chip, trying to stick deeper on it, at this moment they press the heel of the lock at that moment (I pressed a small selection), it will be free, and then you will be free.). Next, we release the wire from the holders 3 pieces. The womb of the clutch was not visible on top of the clutch, so to the touch. Pull the wire.

For proper power supply, it is necessary to submit plus + to the contact "chips", located with a rectangular side of the "chips", and minus - to contact the contact, located with a semicircular side of the "chips". If the polarity is confused, it is not scary, just a pump will start pumping in the other side.

· or Run the engine and give it to work a little, until you squeeze the filter.

2.3 After performing any action specified in paragraph 2.2, the plug filter must be extended to about 5-7mm (the first sealing ring will appear), the gram of 100 oil will turn out (so prepare a napkin or a cloth). Next, very carefully swing the cork with the filter behind the pin, it (filter) is very quickly extruded to the second sealing ring, and then we completely remove the filter with the plug.
!!! There were cases when when the filter of the filter from the coupling with screwdrivers (shell, acute spanning screwdriver, etc.) pierced it through, and oil began to leak through it. Since being acquired by the original set of the filter is possible only on ebay.com, then as a temporary solution (and perhaps permanent) do this: saw off the original plug the damaged part and in its place is pasted a thin cap of Volvo'vskogo kit. It turns out a fairly reliable design. !!!

!!! Need to remember - Which side stood the filter !!! Because It has a check valve.

Also, there is an opinion that the oil pressure reset valve filter (No. 3 below the left) should be located perpendicular to the land. !!!

It must be taken into account when installing the filter.

2.4 Remove the drain plug and oil begins to coalesce through the drain opening (twirled possible to accelerate the wheels).

2.5 By revealing two screws under the hexagon, remove the pump to clean the mesh on it. With effort we get a pump. On it, too (as on the filter) two rubber sealing rings. There is a mesh on the pump, clean it with a brake cleaner on an alcohol basis and / or blow air.

It is very desirable to wash the coupling. Better cleaner brake discs On an alcohol basis, while the coupling is not pure washing. The coupling can be washed without parsing. In any case not to use the DB-shki karbyuratorki, etc. -.. They corrode the rubber parts of the coupling.

We dress up a balloon with a cleaner with a pipe, we stick into the bay hole, and knock out all the trash under pressure with alcohol couples. You can also through the landing place of the pump, and through the planting place of the filter.

Through the deepening of the place where the filter sits (housing) washing is carried out in the following order:

- At first, carefully remove the dirt (napkin or cloth) from the deepening of the place where the filter is sitting (housing coupling). !!! It is important that this dirt does not get into the central hole (where the filtered oil is already received), since if you drive the dirt into the central channel, it is possible that the coupling will refuse: the dirt particles can get into the inlet valves of the second circuit, and in the adjusting valve - solenoid . !!!;

- After washing, blow all the compressed air to evaporate the alcohol. These are three holes: the filter, the filter place, the place of fastening the pump.

2.6 Set the pump: Lubricate the pumping hole of the pump and 2 of its sealing rubber rings, we set the pump to the place, we enjoy the screws and start tightening them alternately, if necessary, tapping the pulmonary-wooden china with a pump. We looked a little, pulled up. Just with hands (without tapping) Install the pump in place is hard. Connect the "chip" of the pump to the clutch block.

2.7 set a new filter Couplings in place. To do this, set the filter element from the Volvo'vsky kit the right side to the sealing plug, lubricate the sealing plug and the tube itself with 2 rubber rings itself. And, without allowing its skew, carefully install the collected "design" in the coupling to the disappearance of the second cut.

2.8 Spin new or old drain bolt. with a moment of 30 nm.

2.9 Pour a new oil through the filler hole. Filed oil should be warm - about 30-40 degrees Celsius (if the replacement is carried out in cold weather, then the oil can be carried out in advance on the battery). Remember that the filling volume of the coupling - 720 ml, immediately climbs only 600 ml. Therefore, the bay of the oil along the edge of the filling hole, its (hole) must be closed with a filler bolt with a moment of 15 Nm.

Next, you need to connect the lace "Vasya Diagnost", run the program and transfer the test of actuators again and once again rear driveBut to make it to the end, a little longer thanks to work the engine, whatever he drove the oil through a new filter (somewhere about a minute). After that, again adding the oil in the coupling - should fit just a rest of about 120 ml.

Instead of using a lace (well, or after its use, if not 120 ml has been fed.) You need to drive on the car so that the four-wheel drive connects, i.e. Earned the coupling, and after adding the rest of the oil, tighten the bolt with a moment of 15 nm.

PS: Infa with Land Rover Club:

The cover of the block control unit of the coupling is made of aluminum. After the 4 years of operation in Moscow, this cover has a property to rot from road reagents. Small holes appear in it, as if someone had a needle. Through these moisture holes makes their way to pCB In the result, there is a lacquer on the board, the board will raw, rot the tracks. Next they burn. In order to avoid corrosion, the control unit cover is processed in advance with anti-corrosion protection ("Movil", etc.).

For writing this document All the material is taken from the forum http://forum.tiguans.ru/, from the topic "Replacing an oil in the Haldex couphe", then generalized. I am gratitude to all members of the forum who participated in the collection of information on this topic. This is a huge work and costly!

Yours faithfully,

Insaider_777 (Ilya Gurin).

Replace the oil in the clutch is not so difficult. In order to cope with this task, it is not necessary to be an auto mechanic and have at hand special equipment. It is enough to simply thoroughly examine the theoretical part of the question and skillfully apply it in practice.

Cars for which Haldex clutch is installed

The coupling, as part of the all-wheel drive mechanism, regulates the transmission of torque from the front axle to the rear. Unreasonable replacement Oils in Haldex - one of the most common causes of complete drive. Timely coupling service (oil replacement, elimination of bearing noise) will allow you to maintain your car in excellent technical condition.

Haldex multi-disc clutch is installed on VW brand vehicles, with a transversely located engine. But not so long ago, the coupling of the Austrian manufacturer began to be used by other well-known auto concerns, such as GM, BMW, Saab.

Interesting! Haldex couplings appeared in 1988, and the first serial models were installed on audi cars And Volkswagen.

How often to replace oil

The frequency of oil change depends on the set of factors. For example, the owners of Volkswagen Tiguan is recommended to carry out the procedure for replacing oil in Haldex coupling through every 10-15,000 km run.But the need for such a procedure should be judged in each individual case.

The frequency of oil change in the clutch will affect:

• fuel quality
• mileage mileage
• ecology
• climate (average daytime temperature; seasonal features; temperature differences)

All these factors affect the state of the car as a whole, and on the oil consumption in particular. But for greater confidence, you can spend a test for oil transparency. Before you take an oil sample, you need machine to work for about 10 minutes. The darker the oil, the older it is, and therefore it's time to fill new liquid and change the filter.

What will be required to replace the filter and oil in Haldex couphe

As it was said earlier, there is no special equipment or special knowledge to replace oil in the clutch. Every more or less experienced motorist will cope with this task.

To do this, he will be needed:

• vessel for the drain of spent oil
• set of keys for drain plug and filter covers
• pliers
• gloves with water-repellent effect (conventional rubber gloves are suitable)
• rag
• syringe with a tube for hundred cubes

Important!Caring for the coupling does not tolerate savings. Give the preference of the oil and high quality filter, the service life of the Haldex clutch depends on it. ForVolkswagen.Tiguan is suitable oil G055175A2.

Having finished with the preparatory work, proceeding to the "update" procedure of the coupling.

Filter and Oil Replacement Procedure

Following a simple action algorithm, you can easily handle the task.

Dismantling filter and plums of oil

In order for the oil easily merged, it is necessary to warm up to a temperature of 300ºС. For personal security should wear safety glasses.

Before the oil drain, you need to unscrew the bolts that hold the filter cover, with the help of pliers, remove a thin gasket and the filter for the Haldex clutch.

Then put a vessel to the coupling for draining the exhaust oil and remove the coupling cork.

Pump cleaning pump

For complete maintenance coupling, you need to spend another procedure - clear pump mesh.

You can do this in five techniques:

1. Remove pump connector
2. Unscrew the clamps
3. Get a pump
4. Take out of it two bolts holding the mesh
5. Clear grid from pollution

After that, the grid is installed back and the pump returns to the "native" place.

Pour oil and filter installation

Oil quality will not depend on the Haldex series, whether it is a coupling 4 or last generation. It is worth just to take the habit to acquire only high-quality raw materials of proven firms.

So, proceed to replacing the oil and the new inventory is inventory - Stockwork syringe. By typing oil into it and opening the filler cork, we begin to fill the coupling with a new, clean liquid.

It is impossible to use the old filter to use it - removing it - dispose of immediately.

Installation of a new filter Start by checking seals. If the rubber rings look erased them too, it is worth replacing them with new, otherwise oil will flow through them.

Remember! Before installing the filter, it is necessary to lubricate with oil, otherwise it will "sit down" badly.

After careful check, replacing parts, set the filter cover and fix it with bolts.

At each stage of the installation work, check the degree of clamping bolts. Do not choke fixing bolts as bad as and twist them. And in that and in another case there is a risk of damage to parts. Tightening the bolts, the main thing to attach a reasonable tolik effort is no more, no less.

Checking the oil level

When the oil begins to flow out of the hole, this will mean that the clutch is filled to the edges. Foroil replacement in Haldex couphe in VW Tiguan It will take about 650 ml of liquid. So with proper use, taking into account the filling of the clutch of oil and lubrication of parts, you will leave near the liter of oil.

The procedure for replacing the oil in the Haldex couphe is really not as complex, as it may seem at first glance, which means it is on the shoulder and you.
