How to change the oil in the DSG box. Robotic DSG Gearbox: Device, Diagnostics of Faults, Advantages and Disadvantages Filling a new lubricant

the main / Repair and care

Since the invention of the car, the constructors constantly tried to improve and automate the gearbox. Separate automakers offered their own options for automatic gearbox. So, the German concern Volkswagen developed and brought to the market a robotic DSG box.

Features of the device and work DSG boxes

The DSG (Direct Shift Gearbox) is literally translated as a transmission with direct switching and in the strict value of the word word is not considered to be automatically. It will be more correct to call it preselective gearbox with double clutch or robot. It consists of such a box of the same elements as mechanical, but the switching and clutch control functions are transmitted by electronics. From the point of view of the driver, the DSG box is an automatic with the possibility of transition to manual mode. In the latter case, the change of gear is performed by a special submissive switch or the same box lever.

For the first time, the DSG box appeared on Porsche racing cars in the 80s of the last century. The debut turned out to be successful - in the speed of switching the gear, it exceeded the traditional mechanics. The main disadvantages, such as high costs and unreliability, eventually managed to overcome, and the DSG boxes have become massively installed on serial machines.

The main popularizer of robotic boxes was made by Volkswagen, setting such a box on VW Golf in 2003. The first version of the robot in terms of the number of gears is called DSG-6.

Device and characteristics of the DSG-6 box

The main difference between the DSG boxes from mechanical consists in the presence of a special unit (mechatronics), which performs the gear shift function for the driver.

The composition of mechatronics includes:

electronic control unit;
electro-hydraulic mechanism.

The electronic unit reads and processes information from the sensors and gives the command to the actuator, which is the role of the electro-hydraulic unit.

A special oil is used as a hydraulic fluid, the volume of which in the box reaches 7 liters. The same oil is used for lubrication and cooling clutch, gear, shafts, bearings and synchronizers. During operation, the oil is heated to a temperature of 135 ° C, so the cooling radiator is integrated into the DSG oil circuit.

The hydraulic mechanism with the help of electromagnetic valves and hydraulic cylinders leads in motion the elements of the mechanical part of the checkpoint. The DSG mechanical diagram is implemented using double clutch and two gears.

Double grip is technically implemented as a single block of two multi-disc couplings. The outer coupling is connected to the primary shaft of odd gear, and the internal - with the primary shaft of the motor gear. Primary shafts are installed coaxially, and one is partially in the other.

The two-mask flywheel transmits the torque of the engine to the grip to which the transmission is connected corresponding to the crankshaft turnover at the moment. In this case, the mechatronics immediately selects the following transmission on the second clutch. Having received information from the sensors, the electronic control unit decides on the transition to another transmission. At this point, the second clutch is closed on a two-mask flywheel and instant speed switching.

The main advantage of the DSG boxes before the hydromechanical machine is considered the gear shift rate. This allows the car accelerate even faster than when using a mechanical gearbox. At the same time, due to the choice of electronics, the correct transmission modes decreases fuel consumption. According to representatives of the concern, fuel economy reaches 10%.

Features of the DSG-7 box

During the operation of the DSG-6, it was found that it is not suitable for engines with a torque of less than 250 nm. The use of such a box with weak motors led to a power loss when switching gear and increasing fuel consumption. Therefore, since 2007, Volkswagen began to install the seven-step transmission option on budget cars.

The principle of the new version of the DSG box has not changed. The main difference from DSG-6 is dry clutch. As a result, the oil in the box was three times less than that, in turn, led to a decrease in its mass and sizes. If the weight of the DSG-6 is 93 kg, then DSG-7 weighs 77 kg.

In addition to DSG-7 with dry clutch, for engines, the torque of which exceeds 350 nm, Volkswagen has developed a seven-step box with an oil circuit. This box uses on VW Transporter and VW Tiguan 2 families.

DSG Box Diagnostics

The novelty of the design is the main reason for the appearance of problems in the DSG box. Experts allocate the following signs of its faults:

jerk during movement;
transition to alarm mode (the indicator lights up on the display, you can continue to move on one or two transmissions);
extraneous noise in the field of gearbox;
sudden blocking of the box lever;
leather oils from the box.

The same symptoms may indicate different problems. So, jerks during movement can be caused by faults both mechatronics and clutches of the clutch. An emergency mode indication does not always lead to restrictions in the work of the CPT. Sometimes it disappears after restarting the engine or turn off the battery. However, this does not mean that the problem disappeared. Blocking the selector lever can be caused by freezing the drive cable, any mechanical damage or breakage.

The most problematic elements of DSG boxes are:

mechatronics;
two-mask flywheel;
multi-disc clutch coupling;
bearings of the shafts of the mechanical part.

In any case, when suspicious of the DSG malfunction, the boxes should immediately contact the Volkswagen service center.

DESG Self Self Service

On the issue of the possibility of self-maintenance and repair, DSG boxes have not yet been a common opinion. Some car owners believe that when problems appear, it is necessary to change nodes assembly. Others try to disassemble the box and eliminate the malfunction with their own hands. Such behavior is explained by the high cost service of the DSG DSG repair service. Moreover, often experts explain the malfunctions of the design features and try to avoid work, especially if the car is under warranty.

Independent troubleshooting in DSG boxes requires high qualifications and availability of computer diagnostics. The high weight of the node requires participation in the work of at least two people and strict observance of safety.

As an example, a step-by-step algorithm for replacement of mechatronics can be considered.

Replacing Mechatronics DSG Boxes

Before replacing the mechatronics, it is necessary to translate rods into a dismantling position. Such a procedure will noticeably facilitate the process of dismantling. This can be done using the DELPHI DS150E diagnostic scanner.

The following tools will be required to work:

set of tekes;
set of hexagons;
tool for fixing clutch blades;
set of horn keys.

Dismantling the mechatronics is performed in the following order:

Locate the car on the lift (overpass, pit).
Remove the engine protection.
In the procession space, remove the battery, the air filter, the necessary nozzles and harnesses.
Merge oil from gearbox.
Disconnect the holder of the wire pads with connectors.
Unscrew the fastening screws of the mechatronics.
Divide the clutch block from the box.
Disconnect the connector from the Mechatronics board.
Gently pull on yourself and remove the mechatronics.

Installing a new mechatronics is performed in the reverse order.

Independent oil change in DSG box

DSG-6 and DSG-7 boxes need to be regularly replaced by oil. However, for DSG-7, the manufacturer does not provide this procedure - this node is considered maintenance. Nevertheless, experts recommend changing the oil at least than every 60 thousand km of mileage.

Oil replacement can be made independently. This will save up to 20-30% of service costs. The most convenient procedure is performed on the lifting or observation pit (overpass).

The procedure for replacing the oil in the DSG-7 box

To replace oil in the DSG-7 box, you will need:

internal hex key on 10;
funnel for pouring oil;
syringe with hose at the end;
capacity for draining waste oil;
plug on the drain neck;
two liters of transmission oil corresponding to the standard 052 529 A2.

The heated oil will be fastened to merge with the checkpoint. Therefore, before starting work, transmissia should warm up (the easiest way to make a short trip). Then the access to the top of the box should be released in the rotor space. Depending on the model, the battery dismantling, air filter and row of nozzles and wires.

To replace oil in the DSG-7 box, it is necessary:

Outline replacement procedure in the DSG-6 box

About 6 liters of transmission fluid poured into the DSG-6 box. The oil change is performed in the following sequence:

Locate the car on the lift, the overpass or the observation pit.
Remove the engine protection.
Substitute a drain plug for drainage of spent oil.
Unscrew the drain plug and drain the first part (about 1 l) oil.
From the drain hole to unscrew the control tube and drain the main part of the oil (about 5 l).
Split a new drain plug.
To access the top of the gearbox, remove the battery, the air filter, the necessary harnesses and nozzles.
Remove the oil filter.
Pour through the neck of 6 liters of transmission oil.
Install a new oil filter and spin the lid.
Turn the engine and give it to work 3-5 minutes. At this time, switch the box lever in each position for 3-5 seconds.
Unscrew a drain plug and make sure the flows of the oil from the drain hole.
In the absence of leaks from the drain hole, continue the fill.
When the leaks occurs, tighten the drain plug and set the engine protection.
Turn the engine, make sure there are no errors on the dashboard.
Take a trial trip and make sure that the gearbox is normal.

Reviews of motorists about DSG boxes

Since the appearance of DSG boxes, its design is constantly improved. However, robotic boxes still remain quite capricious nodes. Volkswagen concern periodically conducts a massive review of cars with DSG transmission. The manufacturer's warranty on the boxes is increased to 5 years, it is reducing again. All this testifies to the incomplete confidence of the manufacturer in reliability DSG boxes. The oil in the fire is poured and negative reviews of car owners with problem boxes.

Review: Car Volkswagen Golf 6 - Hatchback - Machine is not bad, but DSG-7 requires constant attention
Advantages: a frisky motor, good sound and noise insulation, comfortable salon. Disadvantages: unreliable automatic box. Had the honor of the ownership of this 2010 in., 1.6 engine, DSG-7 box. It was pleasantly pleased with the consumption ... In the mixed mode, the city trail was 7l / 100km. Also pleased with noise insulation and quality of standard sound. Good pickup in both the city and on the track. The box, if necessary, quick overtaking, does not slow down. But at the same time in the same box and main problems !!! When running 80,000 km. The box started to twitch when switching from 1 to 2 in traffic jams ... How many have already talked to this lack of this box, as well as the previous DSG-6 ...

Review: Car Volkswagen Passat B7 Sedan - Does not justify expectations about german quality
Advantages: Comfortable. Quickly accelerates the turbine. Enough economomen at fuel consumption
Disadvantages: no quality, very expensive repair
It so happened that since 2012, our family has entered the VW Passat B7 car. Automatic box (DSG 7), the most maximum equipment. So! The first impression of course the car produced, and very good, since there were no foreign cars in a similar class in the family. But the impression was short. The first thing began to compare a complete car with other automakers. For example, in Camry, the driver's seat is adjusted by the electric drive, everything has to be done here. Next about the quality of the cabin. Plastic is terrible and ugly, compared with the French or the Japanese. The skin on the steering wheel rubs very quickly. The skin of the front seats (as they are exploited more often) is also very cracked. Magnitol often freezes. Rearview camera including the image simply freezes. This is what is primarily striking. The doors began to open the tight and terribly to creak after a couple of years, and it is not possible to fix it with an ordinary fairy tale. Box is a separate story. After 40 thousand run, the car just got up! When visiting the official dealer, it was found that the box was completely under replacement. The new box costs about 350 thousand, plus the cost of work. Wait box month. But we were lucky, the car was still on warranty, so the replacement of the box was completely free. However, the surprise is not very pleasant. After replacing the box there were still problems. On 80 thousand kilometers, there was a double clutch disc. Guarantees no longer had and had to pay. Also out of trouble - frosted fluid in the tank. The computer issued an error and blocked the flow of fluid on the glass. It was fixed only by a trip to the service. Also, the headwaters of headlamp consumes a lot of fluids, you can fill the entire bottle of 5 liters, it is enough for the day of traveling around the city in bad weather. They corrected this by the fact that the headlight washer turned off. The windshield was heated. I flew the pebbles, the crack went. I do not deny that the windshield suffers very often and it can be considered a consumable, but for replacing the official dealer requested 80 thousand. Expensive however for the consumor. Also, plastic plastic on the door was bored and curled into the harmonica. In this case, the question arises - where is it German quality and what takes such money? Very disappointing. Use time: 5 years Cost: 1650000 rub. Year of Auto Release: 2012 Engine Type: Petrol Injector Engine Volume: 1798 cm³ Transmission: Robot Drive Type: Front Clearance: 155 mm Airbags: Not less than 4 Trunk volume: 565 l Great impression: Does not justify expectations about german quality

MICKEY91 Russia, Moscow

However, there are also owners who are fully satisfied with their car with a DSG gearbox.

Experience using: year or more cost: 600,000 rubles of its faithful assistant "plus-" acquired in 2013, after the sale of VV Passat B6. I will be disappointed, since the car was in two classes below. But for my surprise, I liked even more . Very unusual was the location of the driver behind the wheel. You are sitting in the "bus". The suspension is very "shot down", did not make it possible. Boose a large number of airbags (already 10 pieces) and 8 very worthily sounding audio colors. The machine is really made of metal. When you close the door feeling that it is a "tank hatch", which gives additional confidence for safety. Logger gasoline 1.6 in a pair of 7 stacks DSG.Adsight on average 10 liters in the city. I read a lot about the clothes of the DSG boxes, but here's the 5th year of the car in the family, and there are no complaints about the work of the box (the lungs were from the very beginning). Very spacious salon. Inrew 1.80, it seems easily, and there is an easy place to knee . The service is not more expensive than any foreign car (if only not to go crazy, and not to repair the officials). The disadvantages would be made not a completely economical engine (after all, 10 liters for 1.6 are a bit too much) Well, I would like a tank washer more. In general, as a resume I want to say that this is a faithful and reliable friend. I recommend everything with family! Published January 23, 2018 - 16:56 Review from Ivan1977 5

Transmission DSG7 (Direct Shift Gearbox - direct switching gearbox) This is an automatic transmission (ACP) of this type with "dry" clutches, which VW has developed, in which seven gears and reverse transmission. Switching occur without breaking power flow (switching occurs without inclusion of neutral) This is the main advantage of automatic transmissions, and also provides "creeping" mode at the beginning of the move. Therefore, DSG boxes belong to the ACP.

The flagship in the release of "dry" clutches is VW, they immediately took into account the lack of DSG6 design on the inclusion of one clutch of the transfer forward and forth, and released seven stepped transmission, where in advance and back are different rows.

DSG7 is equipped mainly in cars with a small engine volume, on powerful engines with a high torque "dry" clutch cannot be kept. DSG7 is equipped mainly Volkswagen, Skoda, as well as Audi, SEAT.

Models of cars where you can meet the DSG7 box

A feature of the DSG7 is the presence of two oil volumes, for mechatronics that controls the DSG7 and the mechanical gearbox (where the forks, gears, etc.). If the conventional mechanical CP clutch is clamped with the calculated springs mounted in the manufacture, and when you press the clutch pedal, the clutch "blossoms" thereby not transmitting the moment, then everything happens in DSG7, until the mechatronics gives the clutch signal, they are freely rotated The mechatronics gives a signal, and the piston acts on the plug and the plug clamps the disk, and if there is no pressure leakage in the mechatronics, then the disk is pressed by the necessary effort.

In diagnostic devices there is a temperature value of the first and second friction disc, the temperature is calculated, i.e. As the clutch bucks, how much time, what moment was on the engine or what pressure was in mechatronics, the clutch temperature is calculated based on these indications - this is a non-meaning temperature - this temperature is calculated. If the estimated temperature begins to increase means, the clutch begins to overtakely slip and in the future it will be necessary to repair the DSG7 box.

Ford, Mercedes, Fiat developed their DSG boxes with "dry" clutches. Ford has refused hydraulics by setting the electromotors, which makes the electronic unit combined with electric motors installed on the box. Adaptation of the DSG7 Ford after replacing the electronic unit or double clutch is automatically carried out, unlike the VW where the adaptation procedure is required, special equipment.

The clutch in this box is separate unintended (inexpensive repair) block. When replacing the clutch, the DSG7 is supplied by the manufacturer assembly, with adjusted between disk gaps.

Classic problems with DSG7

The manifestation of defects in the DSG7 work is often associated with improper work of mechatronics.

There is no inclusion of gear forward and back,
Jerks when switching gear.

After diagnostics, the repair of mechatronics DSG7 is required or reprogramming it. Causes may be in pressure leaks on the internal cavictions, or not the correct operation of the transmission software. What leads to a slip of the clutch. Reprogramming DSG7 is required to update software and optimize the box.

It is possible to overheat the mechatronics block in the vehicle motion modes (providing a crawling mode) and as a result of the clutch disc slip, in the future repair DSG7, which is an operational defect in DSG7. The manufacturer recommended actions for the owners of the DSG7 for the compulsory switching of the box from the "D" mode to the "N" mode when the car is in the traffic jam and costs more than 1 minute. The VW developers did not count on the Russian features of the operating conditions of the DSG7 (many hours, regular movement in the "traffic jams").

Also, the failure of the mechatronics DSG7 is to flow oil from "Sapuna", a replacement or repair is required. At the failure of the electrical circuits inside the block, the Mechatronics DSG7 is replaced assembly.

It is required to monitor the protection of the open parts of the DSG7 from pollution. The failure of the "dry" discs is possible for various reasons: hits for the clutch of oil (for example, due to the leaks of the crankshaft of the engine), water, clogging of mud and the like. It is a problem with DSG7 box with dry clutches.

The mechanical part of the DSG7 for large runs inherent in the breakdowns of ordinary mechanical KP - breakdown of the gear, the poverty of bearings, shafts, the destruction of drive forks, etc. Then require careful repair of the mechanical part of the box.

Replacing DSG6 on DSG7 is impossible, because Transmission is aggregated with different engines.

In 2011 In the production of DSG7, a modification of individual nodes was made, improvements were made, the installation dimensions for clips were changed, the refrigerant drive lever was changed.

Owners of cars with DSG7 face the problems of the ACP

shock when turning on forward or backward,
boots when switching,
vibration ACP,
slobs on switching,
the car includes emergency mode.

The average operational mileage of the car with DSG7 is 90-150 thousand km. Repair and replacement of clutch is performed using a special tool. Repair of DSG7 It is required to strictly comply with the assembly and adjustment technology, according to the manufacturer's plant.

Replacing the oil in the DSG7 box, it is possible to produce only in the gearbox. Replacement can be performed on average after 40 thousand runs or as needed, because The manufacturer floods the oil for the entire service life.

Software updates are the advantage of DSG7. At the first signs of improper DSG7 work, you should start with diagnostics and, if necessary, perform the "flashing" of the mechatronics if they are released by the manufacturer for your car, but do not recommend to "reflash" a regular working DSG7.

Diagnostics and advice on the DSG7 box

ATG service engineers provide technical support in the form of consultations on technical issues related to repair and operation DSG7. You can get an operational consultation by calling or send a request from the company's website

When diagnosing DSG7, many work parameters may be checked, read by specialized test devices. Decoding and analysis of received codes of the box work allows you to find the cause of the incorrect operation of the ACP and prevents the DSG7 breakdown by the timely detection of defects. One of the moments of DSG7 diagnostics is to control the coupling temperature in operating modes. Clutch wear can be viewed software.

Checking not tightness, oil replacement, it is possible to produce in the ATG service center and is a necessary procedure aimed at maintaining the ACP in an efficient technical condition, in order to increase the deadline for its trouble-free operation.

ATG has a special tool and equipment and can produce all restoration work. We have experience in competent, qualified maintenance and repair of the DSG7 automatic transmission in Moscow.

DSG is a special kind of transmissions. This mechanism combines the principles of operation of automatic and technology and the preselative mechanism itself occurs on VAG cars. The main plus of such a box is that it is performed very smoothly. At the same time, power is not lost, which has a positive effect on economy. Many car owners are interested in how the DSG-6 oil is replaced, because the mechanism is quite complicated.

Benefits

When using this transmission, the transmission is not at all. The owners argue that the movement on such a PPC is comparable to the variator. There are no shocks when switching, which are characteristic of mechanics and machine gun. And this is definitely plus.

But on this, the positive aspects of the transmission do not end. Another weighty advantage of the DSG system is economy. VAG specialists conducted a series of tests, as a result of which it turned out that savings with these boxes is about one and a half liters of fuel at 100 kilometers, which is quite essential. And this is despite the fact that the power unit was the same on DSG and a simple automatic transmission.

The 6-speed DSG has internal DQ-250 labeling. Unlike seven-step analogs, it has a serious constructive feature. The grip here works in the oil bath. Therefore, the transmission is called "wet." It is impossible to burn such a clutch, as on seven-step DSG. But at the same time there is more oil for the box, than for more modern seven-step systems.

This advantage requires the owner of the regular oil replacement on the DSG-6. But 7-speed units operate in dry conditions - here the clutch in the bath is not immersed. Therefore, the replacement of oil on factory regulations is not needed.

Device and principle of operation

In general, this is an ordinary mechanics, but the transmissions are included with a robotic mechanism without power loss. This DSG is different from traditional mechanics. In the MCPP, the torque is interrupted when the clutch is squeezed. When taking the rotational moment, the fuel is spent just like that. PPP DSG add speakers and efficiency cars.

The main thing that distinguishes these boxes from any other, is two clutches. But in fact, it is still more difficult. Boxes are also two. They are in one case. If two gearboxes are used, then the primary shafts are also two, with a separate clutch for each.

On one shaft installed gears for odd gears along with the back. At the second, the gears are even fixed. After the machine is touching on the first gear, the second is already included and ready for switching. When electronics decides that it is time to change the transmission, the adhesion of the primary shaft will turn off, and the second quickly picks up the torque without any loss in power.

Gears are included by ordinary synchronizers. The plugs are powered by hydraulic cylinders. The clutch is also turned on and off through the hydraulic system. Manages all this mechatronics. This is the main electronic and hydraulic node. Another transmission shaft is made by hollow. Inside it is a shaft of odd speeds. It is thus that VAG engineers managed to establish two mechanical gearbox in one case.

Typical "diseases"

To replace the oil DSG-6 is necessary strictly according to the manufacturer's regulations - they can be seen in the instructions for the machine. Almost all type breakdowns occur due to late change of transmission fluids.

Very often wearing a multidiscory most often this is manifested in the periodic absence of loading of the reverse gear and in the jerks when switching even gear. PPC can go out into emergency modes. At the same time it is impossible to enable odd transmissions. Repair of DSG in this case - replacement of the friction clutch entirely or replace individual disks. Next, the basic setting and adaptation is performed.

Also, one of the problems of these boxes is the wear of solenoids that regulate the pressure in the mechatronics. In this case, you can feel jerks when switching. Errors breakdown does not cause. Solve the problem can be replaced by solenoids. Also performed the complete replacement of mechatronics in some cases.

Certain problems with the electronic unit of the mechatronics can appear. They are usually detected with a cold start of the engine. The DSG-6 box once will go into emergency mode. Sometimes for the same reason, the PPC can periodically switch to emergency mode. Restore work can be replaced by mechatronics or repair block.

Often the masters are diagnosed wear and other bearings. Differentials also fail. This is manifested by increased noise when driving, braking, acceleration. It is possible to solve the problem with the overhaul of DSG using high-quality used spare parts.

When to change the oil?

We change oil yourself

To replace the transmission oil, you will need six VAG G052182A2 liquid liters, an oil filter, a drain plug-ring sealing ring.

Some drivers when replacing oil on DSG-6 prefer to use not "vagovskaya" products, and transmission oil Pentosin FFI-2. It has a smaller price, all the necessary tolerances and guarantees the stable operation of the PPC with double clutch. The main thing is never under any circumstances to mix this product with Vagovsky.

Stages of the process

First of all, the car rises on the lift or is installed on the pit. It is recommended to install on parking. Next, unscrew the drain plug on the CATER CARTER. Initially, a liter of fluid will fall out of the box. Then you need to unscrew the control tube - from there will turn out about five liters. If the chips flow together with the oil, then this is a reason to contact the service for repairing the box.

Next, the filter is replaced. On many cars (including on Skoda) with the DSG-6 filter is above. To access it, you need to remove the battery along with the playground, the air filter housing and air ducts. Then you can unscrew the filter.

Pour new oil

Then you should pour into a preselective gearbox DSG-6 new liquid. Some pour it directly into the filter hole. But it is very long. It is best to find a special adapter that screws up instead of a plug for the oil bay, and two meters of hose. The hose is tensioning the funnel and pour the product.

According to the manufacturer, about seven liters should be included in the box. But in reality only five. Next launch the engine, and the funnel holds where it was. Then the box switches to different modes. After that check the level.

The funnel is removed, and instead they put a bottle with butter. The bottle must be installed on the floor. It will flip over the oil. When the liquid stops flowing, and only drip, the adapter can be unscrewed.

Check

On this, the replacement of DSG-6 oil is finished. The oil plug is twisted, the box is installed on parking, and the engine is not devoured. Determine the temperature of the oil will help special equipment from VAG. Next, unscrew the cork and look, whether oil dripping. If so, then it gives it to drain. If not, then tighten and repeat the procedure.

The manufacturer himself declares that the DSG robot is characterized by high reliability and is a profitable solution compared to traditional hydromechanical automatic transmission or variamators. Anyway, it is important to understand that this box needs regular and high-quality maintenance, taking into account a number of features of its design.

Under such service it should be understood primarily to replace the oil in DSG, as well as DSG. Next, we will talk about when oil in the DSG needs to be changed, as the oil change is performed in the DSG box, as well as to pay attention to this procedure.

Read in this article

Replacing transmission oil in the DSG robot: when you need and why

So, the determination of the PPC is a manual box, as well as (by analogy with the MCPP). In other words, in contrast to the "classic" automata or variator, the hydrotransformer is absent.

At the same time, the clutch disks are two, thanks to which the transmission switches very quickly and smoothly. As a result, a high level of comfort and fuel efficiency is achieved, as well as an impressive overclocking dynamics, since there is practically no power breaking in the moments of switching, etc.

Manages the operation of the box and clutch, as well as (analog). In fact, the electronic unit sends signals to actuators, after which due to the redistribution of fluid flow (oil) in the mechatronics, the gear and control of other processes occurs.

It is quite obvious that the presence of such a device as a mechatronics means increased requirements for the quality and state of transmission oil. In other words, a timely oil change in the DSG box is needed.

Immediately note, according to the regulations, the oil change in the DSG-6, as well as often in DSG-7 every 60 thousand km is necessary. However, if the car is operated in difficult conditions (trailer towing, aggressive ride, maximum loads), replace the transmission oil before earlier (the interval is reduced by 20-30 or even 40%).

Please note the DSG-6 is and can exit about 200-250 thousand km. without repair. It is important to understand that the result of a late replacement of oil in a box simultaneously with a violation of the operational requirements for the PPC is the overwhelming majority of the DSG breakdowns.

Also, after replacing the oil, most owners note that after replacing, for example, in DSG-6, shocks are disappeared when switching, the box works smoothly without jerks. Next, we consider the oil replacement process in the DSG-6 with your own hands.

How to choose and change oil in DSG

So, in order to change the oil in DSG, it is necessary to select a special transmission fluid in advance or the oil in the DSG box, which is suitable for the units of this type. To replace the oil in the DSG box, for example, DQ-250, 6 liters of transmission oil will be required.

If we consider that such a gearbox with a "wet" clutch (clutch packages are immersed in the oil bath), oil in this case needs more. As for DSG-7 with the so-called "dry" clutch, a smaller amount of transmission fluid is required to such a box.

We also note that besides the fluid it is necessary to change the oil filter of the DSG box, as well as a special sealing ring of a drain plug. As a rule, when replacing original oils and transmission fluids with VW TL52182 tolerances are used. You can also select suitable analogs of third-party manufacturers.

The main thing is to use high quality products as well. If we talk about the replacement itself, you can use the services of specialized service stations, and do all manipulations yourself.

First of all, besides oil and a PPC filter, a garage with an observation pit or a lift, a set of tools, tanks for draining testing, rags;
Before you begin to replace the box, you need to warm up by passing by car about 10 km;
Next, the car is put on the pit or rises in the lift, if there is a removal of engine protection;
Then it will be necessary to remove the air intake along with the air filter, the battery with the casing and pallet;
The plastic cup is turned off, the filter is retrieved;
After you need to remove the cap of the Sapuna (located closer to the pala from the filter);
Now you can go down to the car and unscrew the drain plug, substitute the container where the development will be merged;
After unscrewing the plug into the hole, the hexagon key is inserted, which twisted the special insert. This allows you to drain the maximum amount of oil;
After seizing inserts, you need to wait until all the oil is in the container;
In parallel, it is necessary to impregnate the new DSG box filter with fresh butter. To do this, you can insert a filter into the case and shed it with oil;
After the oil completely merged from the checkpoint, the insert can be spinning, but it is not necessary to twist the drain plug if it is spinning, the oil will be inserted into the unit faster;
To avoid oil leaks, a container should be placed in the drain hole area.
Now it remains to insert a funnel in the Sapun gearbox (from above under the hood) and pour fresh oil. Pulling should be slow and gently, dosing portions.

We also add that it is possible to pour oil in other ways (for example, download the syringe through the drain hole), however, in practice, refilling through the Sapun is the fastest and efficient. Also, after about 4.5 liters of oil was flooded in the box, you need to spin the cap cap cover, put the cap cap, set the previously removed elements of the engine inlet system, connect the terminals per battery.

At the same time tighten and spin nothing yet. In parallel, the old drain plug of the gearbox is installed (we do not yet set a new one, and sealing rings are not changing). Next, the engine must be started by connecting it in parallel to the ECU through.

The main task, wait until the oil is warmed in the DSG to 40-48 degrees. After such heating, the engine is not necessary, while the old drain plug should be unscrewed. It is important that the oil is a little bit from the hole as a result of the vibrations of the conducted internal combustion.

Then you need to wait for a while until the surplus is flowing, that is, the required number will remain in the checkp) (the insert-plug-insulated insertion will allow you to learn more lubrication). Please note if, when you unscrew the cork, the oil immediately does not eat, this suggests that it is insufficiently insufficient and needs a fusion.

After the oil stops dripping, it will indicate the desired oil level in the checkpoint. In this case, you can tweak a new plug with a sealing ring, as well as jamming. Now you can proceed to the back assembly, tightening all the previously removed and unacted items. On this oil replacement can be considered completed.

That in the end

As can be seen, although the DSG box is not a "classic" machine and is more like a manual transmission, all the same, the replacement of oil in DSG should be made more often and performed regularly.

The reason is the presence of mechatronics and increased sensitivity to the transmission fluid in the checkpoint. The regulation of the manufacturer itself also indicates the need for replacement, that is, such a box can not be considered officially non-maintained.

It turns out that the owners of auto models with DSG-6 must take into account that the life of the transmission directly depends on the timely replacement in the transmission of oil and the CAT filter. It is also necessary to comply with certain rules of operation (avoid sharp starts, high loads, slip, trailer towing and other cars).

Finally, we note that the oil change in the DSG-6 or DSG-7 box in some cases allows to improve the quality of the gearbox itself, get rid of jerks when switching, the car is better accelerated, the transmission is less than noise during operation, it vibrates so much, etc. P.
