Direct Shift Gear Box (Direct Shift Gearbox) or DSG is a robotic gearbox in which there are two clutches at once, developed by Volkswagen.

Structurally, such a box is a manual transmission, but gear changes and clutch operation are carried out using mechanisms controlled by a computer.

Of course, such a box has its advantages. Due to the double clutch, gear changes are faster and easier, better dynamics, less consumption. One clutch is responsible for engaging even gears, the other clutch for odd gears. Due to this, the main problem of robots was solved, in sharp gear changes at high speeds. This is where the pros, however, end. The disadvantages of this box are very low reliability and high repair costs. They make second-hand DSGs a nightmare for second and third-party owners who have bought a vehicle that is out of warranty.

The main problems and disadvantages of operating this box are the very rapid wear of the dry clutch, due to the not entirely correct operation of the mechatronics and its control unit.
There are, of course, other drawbacks to the box design - contamination of sensors, souring of solenoid contacts, wear of other mechanisms (clutch release fork, shaft bushings, etc.) to a new one. In addition, there are often problems with spare parts from suppliers, parts are rare on sale and they will have to wait for several weeks.

Despite the fact that the manufacturer fulfills all its obligations and the guarantee for the assembly is quite impressive, this checkpoint in Russia has given rise to serious passions.

Deputies of United Russia and representatives of the public movement "Automobile Russia" even wanted to ban the import of DSG-7 boxes into our country. This behavior is not at all another unhealthy initiative of the authorities to solve strange problems. Many meetings with journalists and experts of the Volkswagen company end with logical questions: when will engineers make the box reliable and its typical problems and disadvantages will be resolved. The answers are always the same, they say, everything is fine with the box, follow the operating instructions, if something is wrong, there is a guarantee, the car with our checkpoint drives quickly and economically. True, as noted by the drivers, not for long.

From Volkswagen followed a statement, the essence of which was that the company will fulfill all obligations to customers faced with low-quality products, but only if the guarantee is in effect. At the moment, the official representative office of Volkswagen in Russia gives guarantees for this unit, if the car is new, up to 5 years, or the obligation is valid for 150,000 mileage, depending on what happened first. In the event of a warranty case, the company's representatives will replace the failed parts and mechanisms or the box itself, if necessary and completely free of charge.

Operating rules

In order for the box to live for a long time, you should familiarize yourself with the rules of its operation, read the instructions and understand how it works. Here are some tips:

1. For correct operation, the transmission should be warmed up before driving;
2. It is important not to allow any slippage and aggressive driving;
3. Overcome tight congestion in the S position without switching to neutral;
4. The oil should be changed every 50,000;
5. For a dry clutch, it is best to switch to neutral during long stops.

If you ignore the respect for this mechanism, then soon problems will arise with it and expensive repairs will be required.

Change of oil

Volkswagen writes that changing the oil at these gearboxes is necessary only for repairs - the oil is filled for the entire service life, while the car is in operation, it is not recommended to change it. If the gearbox has been repaired, then an oil change is necessary every 60,000 kilometers. Service station specialists who have already faced the repair of these gearboxes claim that in any case, an oil change is necessary every 50,000 kilometers, otherwise no one can guarantee that the gearbox will last a long time.

DSG 0B5 has two lubrication systems (gearbox housing and mechatronics). There is another oil in the mechatronics unit, specially developed for 0B5. In no case should such oil be drained from mechatronics. Modification 0B5 was installed on the Audi A4 car, from where it migrated further on models A and Q.

If the oil is changed by hand, then another nuance awaits the motorist. There is no filling hole, a suitable hole can only be found under the battery. All problems can be solved if you know what to do.

Oil for replacement is suitable for G52512A2, you need to fill in 1.7 liters (5.5 for a complete replacement). An oil change can be cheaper if you use an analogue of SWAG 10 92 1829.

In general, an oil change is no different from a similar procedure for an automatic transmission.

Can a robot tow a car with a box?

It is not recommended to tow a car with a DSG box. The box may be damaged by the transportation procedure itself and this case will not be covered by the warranty. The official service station may refuse to repair due to violation of operating conditions. It is advisable to call a tow truck. If this is not possible and you still need to tow the car, you should do the following.

1. Switch on the ignition;
2. Shift the transmission to the neutral position (towing at speed is not recommended and may damage the transmission).

Towing is allowed to a distance of no more than 50 kilometers at a speed of no more than 50 km / h.

The opposite situation, when another car needs to be towed by a car with a robot box, is also not safe. In extreme cases, it is necessary to put the box in manual mode and move only in first gear and it is better not to exceed the speed of 30 km / h.

Tow truck for transporting cars

DSG adaptation

Adaptation is a procedure for adjusting the operation of the gearbox and mechatronics unit, which is necessary after repair and in some cases when the gearbox does not work correctly. The procedure is simple and you can do it yourself. Usually adaptation is done via Vag Com. Vag Com is a diagnostic program that allows you to "make friends" a car with a computer, diagnose and configure some systems. The program has a simple and intuitive interface, it takes up little disk space and it has its advantages compared to its counterparts. For the adaptation to be carried out correctly, follow the following algorithm:

- The box is in position P and warmed up to 30–100 degrees C;

- The engine is running;

- The brake pedal is depressed during the entire procedure.

If all conditions are met, it is necessary to connect Vag Com. The adaptation is done as follows:

1. In the program interface, we find the item Basic automatic transmission settings.
2. Select the item Gearshift clutch settings, press "Go!". The box will start making sounds, and the numbers in the program will change. You have to wait until it stops.
3. Select the point Gear change points, press Go. We wait similarly to point 2.
4. We select the Clutch adaptation item, the actions are similar to paragraph 2. Then we do everything in the same way as in paragraph 2.
5. Item Basic settings.
6. Item Pressure Adaptation.
7. Item With the gearshift paddles installed.
8. Item ESP and Cruise.
9. Click Done.
10. Turn off the ignition.
11. We are waiting for a few seconds.
12. We turn on the ignition.
13. We look for errors, delete if necessary.
14. We leave the controller.
15. Without using cruise control, we carry out a test drive.
16. Quit them Vag Com. The adaptation is complete.

Replacing the mechatronics unit will require a new firmware. Fortunately, this is easy to do. The control units for mechatronics DSG 6 and mechatronics DSG 7 can be easily reflashed using this program.

We repair DSG

If there are jerks and kicks during the operation of the box, extraneous noise, then it's time to go to the diagnosis. DSG repair is difficult enough

The dual clutch on robotic gearboxes, despite all its advantages, is a consumable item. It does not matter "wet" type of clutch or "dry". With aggressive use, twin clutches barely survive up to 40,000, it is better to change it as an assembly at the first symptoms.

The mechatronics unit is a very delicate unit that requires careful handling, heating and does not like overheating. One of its weak points is the cooling system pipes made of plastic. From temperature extremes and vibration, they can burst or crack, which will lead to coolant leaks and overheating of the box. Moreover, the checkpoint can overheat from prolonged standing at a traffic light at speed.

The heat exchanger block can generally depressurize and mix oils with antifreeze.

Output shaft roller bearings can travel less than 50,000 if subjected to heavy loads. When a gear tooth breaks, a characteristic knock will appear, which is also not uncommon. Also, extraneous noise in the box may indicate wear on the input shaft bearing, other bearings of the mechanical part, and the box differential. When the engine speed rises, stops, turns, the noise usually increases.

A breakdown of the electric pump of the control unit will immobilize the machine. If some electrical circuit in it is acidified, this behavior can be intermittent. A faulty control unit can periodically throw the box into emergency mode.

The wear of the solenoids can lead to jerking when shifting gears, the self-diagnosis system will not see the problem. If you do not pay attention to such signs, then, most likely, soon the box will completely "stand up". Repairing it is not cheap and has not yet been mastered very well in Russia. It may even be difficult to find a suitable service with specialists who will take on such work. Before buying a car with a robot, think about whether all its advantages are worth such repair problems.

The DSG box, like all similar boxes, is a fairly early development and they are just beginning to be modernized and tested. The manufacturer's warranty so far covers all possible troubles. Until the moment when eternal robotic boxes appear, as American and Japanese automatic transmissions once appeared, for a long time, maybe 2-3 more generations of these gearboxes.

Usually everyone is used to seeing a manual or automatic transmission in cars. But there is a new generation gearbox - DSG. Its structure includes both mechanics and automatic transmission. In other words, it is called a semi-automatic or dual-clutch transmission. This type has long been used in sports cars. In the production of conventional cars, it is still considered a new technology. However, the modern car enthusiast simply needs to know about the DSG gearbox - what it is and how it works.

The developers of automotive hardware, Borg Warner, decided to create a transmission that combines the qualities and characteristics of an automatic transmission and a manual transmission. They created a six-speed gearbox, but it didn't work with low-powered cars. They later came up with a seven-speed gearbox, but the clutch was dry and the robot quickly heated up. After a year of hard work, the company decided to test its development on Volkswagen vehicles. The first batch of robots was released with defects, but soon everything was fixed. DSG is now popular in today's automotive world.

Box DSG7

How does the DSG gearbox work?

At the moment there are two modifications of the transmission: a six-speed wet clutch and a seven-speed one. Each has some peculiarities or disadvantages, but more about them later.
7-speed consists of:

1. The first output shaft.
2. Second output shaft.
3. Main transmission.
4. Input shaft.
5. Mechatronic.
6. Oil filter.

The first cars with DSG were cars of the Volkswagen AG line. It was they who left the assembly line and announced this technology to the whole world. This gearbox is still being manufactured at the plant. So what is a DSG box? It consists of 5 shafts, which are connected by gears and 2 clutches. With this technology, they form a kind of mechanism that is very different from classic gearboxes. It is he who is responsible for the fast acceleration of the car and high speed, as in cars with mechanics.

Internal arrangement of DSG

Due to the fact that gear changes are very fast, the DSG gearbox began to be implemented in sports cars, where it is very important.

What is special about a dual-clutch transmission and manual transmission?

The newest gearbox works very quickly and smoothly. All gear changes instantly - this is the trump card for racing cars, where speed comes first. The transmission is different from the mechanics. Let's recall the principle of the manual transmission:

1. When the driver engages the clutch, the engine is separated from the transmission, thereby stopping the flow of power to the gearbox.
2. After moving the gearbox lever, the gear clutch transitions from one gear to another, despite the fact that they are different in size.
3. During this process, the rotation speed of the clutch is gradually equalized, which leads to the inclusion of the next gear.
4. When the clutch pedal is released, the transmission is reconnected to the engine, the torque is started, which turns into the rotation of the wheels of the car.

Each process is not physically felt by the driver, but if an inexperienced driver is driving, then due to the stopping of the power flow from the engine to the transmission, there is a jolt that the driver feels with the passengers in the cabin. The principle of operation of the DSG includes the process of the mechanics and the automatic transmission. There is no clutch pedal here. There is 2 automatic clutches that handle odd (first) and even (second) transmissions. The gears shift with irresistible smoothness. This is facilitated by the electronic mechatronic transmission control system.

In DSG, the gears are located on different shafts. If there was only one shaft in mechanics, then here the even and odd ones are placed on the first and second output shafts. In this case, the internal shaft is placed in the external one so that even gears work from the external one, and odd ones from the internal one.

DSG robotic box

Expert and user opinions

User reviews of the checkpoint are completely different. We propose to consider in detail all the pros and cons of this gearbox. For example, those who have used technology love it. There are a number of reasons for this:

• less fuel is consumed. A car on a DSG box requires 10.2 liters of fuel per 100 kilometers, which is even less than in a manual transmission;
• fast and smooth gear shifting;
• for racing competitions, cars with a DSG box are clearly suitable, because when you turn on a gear, the next one is already ready to be activated;
• the robotic gearbox can operate both in automatic transmission and in the manual gearshift mode for the convenience of users (like a tiptronic);
• no loss of speed and power (almost comparable to mechanics).

The checkpoint also has a number of negative factors, which real users noticed during the use of the box. You can find negative reviews on the DSG transmission, which even discourage motorists from buying a car with a semi-automatic gearbox:

Now you know why DSG is criticized in the modern world, as well as how the installation of a gearbox can turn out when driving aggressively on the roads of large cities.

Let's summarize the above

The DSG semi-automatic transmission is a state-of-the-art technology that combines the elements of an automatic and a manual transmission in one housing. The technology is controlled by the electronic mechatronic system. Used in expensive or sports cars where you need to quickly change gears. On the one hand, it is worth taking cars with DSG, but on the other hand, this is not an option for normal road driving. After all, a car can behave unpredictably, and reliability is an irreplaceable factor that every owner of his four-wheeled friend must be sure of. The speed and smoothness of gear shifting, lower fuel consumption are, of course, good, but everything will recede into the background if the car gets into an accident due to the transmission in a traffic jam or any other accident happens.

What is DSG? From German, the abbreviation DSG stands for "direct transmission" (Direkt Schalt Getriebe). It is often called "preselective", that is, it is able to keep ready gears for the next shift.

The idea of ​​creating such a checkpoint belongs to the French inventor Adolphe Kegresse. In the 1930s, an automotive engineer collaborated with Citroen. He proposed to install a unit with two clutches and hydromechanical control on the front-wheel drive Citroen Traction Avant. The new transmission was not widely used due to its complex design.

The technical consultant Volkswagen Favorite Hoff Maxim Ponomarenko spoke about the advantages and features of the box.

How DSG works

The fundamental difference between the preselective automatic transmission and the others is in two clutches that quickly change gears. In a "mechanic" or robotic box for changing gears, the clutch disc is disconnected from the flywheel, the driver or robotic computer selects the desired "speed", and then the disc gets into place. During this time, the torque is not transmitted to the box and the car loses its dynamics.

DSG eliminates power dips. At the heart of the box is the work of two shafts located coaxially: the first is hollow, and the second is inside it. The engine is connected to each of them through its own, separate multi-plate clutch - also external and internal. On the primary, that is, the external shaft, gears of even gears (2-, 4-, 6th) are fixed, on the internal - odd ones - 1-, 3-, 5th and reverse gear.

When the car starts, a disc with an odd row is pressed against the rotating flywheel, and the disc with even "speeds" is open. During acceleration, the computing unit of the box gives the command to prepare the second gear, so that at the moment it is turned on, disconnect the disk of the odd row and immediately start up the disk of the even one. Tuned shift control ensures no loss of torque.

The robotic gearbox DSG 6 entered the Volkswagen conveyor in 2003. The dual clutch on it worked in an oil bath, receiving the name "wet". The oil in such a box takes away some of the power, increasing fuel consumption. In 2008, the German automaker introduced the seven-speed DSG 7 with a dry clutch.

DSG Benefits

• The DSG gearbox, due to the optimal modes of inclusion of the required "speeds", allows to reduce fuel consumption. Cars with it consume about 10% less fuel than cars with a conventional gearbox.
• A distinctive feature of all such transmissions is dynamic acceleration. To change the gear up, the box needs only 8 ms, it does not have the rubber traction effect of hydromechanical automatic gearboxes.
• You can drive DSG in manual mode, that is, manually change gears.
• Such an automatic transmission is 20% lighter than a similar hydromechanical transmission.

Disadvantages of DSG

• The cost of automatic transmission affects the price of a car, significantly increasing it.
• An expensive oil change (on a six-speed box) every 60 thousand kilometers. The total volume is 6.5 liters.

The preselective gearbox is installed on different models and brands, united under the name of the Volkswagen auto concern: Audi TT (A1, A3, A4, S4, A5, A7, A6, Q5, R8), SEAT Ibiza (León, Altea), Škoda Octavia (Superb, Yeti), Volkswagen Polo (Golf, Jetta, Touran, New Beetle, Passat, Passat CC, Sharan, Scirocco, Caddy).

DSG Extended Warranty

Among many car owners, the dubious glory of the double-clutch box has been entrenched. The DSG name itself has become a symbol of an unreliable design with costly repairs. In fact, Volkswagen has long since taken control of the situation. An important step towards quality control is a large-scale service campaign.

The concern gives an extended warranty for seven-speed gearboxes manufactured before January 1, 2014. According to the representatives of the auto concern, the designated date corresponds to the appearance on the conveyor of the modernized transmission without the typical problems of the previous generation. Special conditions of service are limited to 150 thousand mileage or 5 years of age of the mechanism. The service action includes the replacement of synthetic oil with mineral oil, which is less aggressive in relation to electronic components. In this case, the firmware of the automatic gearbox control unit is updated. Found faults are eliminated free of charge - this applies to repairs, replacement of individual elements or the transmission assembly.

In any case, the abbreviation DSG should not be afraid: with the proper level of service, it will not let you down, and in terms of the number of advantages, the “smart robot” outperforms the classic automatic transmission. And the DSG box will require less money for repairs in comparison with a conventional "automatic".

What malfunctions are typical for DSG?

The most common problem is the jolts when changing gears accompanying the movement. The clutch discs close too sharply and the car jerks. The second known drawback is vibration at the start, clanking, grinding and other extraneous noises during speed changes.

The main reason for the incorrect operation of the seven-speed transmission is its "dry" clutch. It wears out quickly due to severe operating conditions in dense city traffic, with congestion at low speeds. Therefore, the question "how to operate the DSG?" there is one obvious answer - to avoid the "gas-brake" mode, because the main enemy of the robot is a traffic jam.

Among other problems: wear on shaft bushings, clutch release forks, broken solenoid contacts, dirt on the sensors and oil in antifreeze.

How to determine a DSG malfunction when buying a used car?

• Individual gears do not turn on - the box "jumps" them.
• Gear shifting is accompanied by blows - the box "kicks".
• There is a hum when moving.
• The car vibrates at the start.
• Inspection on the lift shows oil leaking from the box.

If there is a suspicion of incorrect operation of the box, it is worth ordering an additional check, or postponing this option.

The robotic DSG transmission is the main gearbox for cars that are part of VAG (Volkswagen, Seat, Skoda, Audi can also be attributed here, although the DSG is called S-tronic there). Recall that today there are three types of DSG - two with a wet clutch and one with a dry one. The first is the six-speed DQ250 and the seven-speed DQ500, the second is the DQ200, which has received dubious fame for reliability.

In our today's article, we would like to talk in detail about DSG 6, discuss its reliability, talk about cars that are equipped with it in 2018, ask the owners for their opinion, then they think about the robot, its pros and cons.

What cars are equipped with DSG-6

First of all, let's take a look at the list of new cars that are equipped with a six-speed wet clutch DSG that are on sale in Russia in 2018.

The Czech brand, which is currently owned by a German concern, as a result of which all the technical stuffing of cars is completely similar to Volkswagen. A robot with a clutch in an oil bath, installed mainly on all-wheel drive, or on powerful models, which include

• Kodiaq- on the crossover, the robot is available with a 1.4-liter petrol engine with a capacity of 150 hp. and all-wheel drive:
• Octavia and Octavia Combi- in both body types, the DQ250 is available with the top-end for the model 1.8-liter gasoline engine with a capacity of 180 hp. and all-wheel drive
• Octavia scout- essentially the same station wagon, only with increased ground clearance and the presence of plastic protection around the body
• Octavia rs and Octavia Combi RS- this sports car is equipped with a 2.0 liter gasoline turbo engine with 230 hp. and front wheel drive
• Superb and Superb Combi- here the six-speed controller is installed on a front-wheel drive version with a 2.0-liter 220 hp engine. and an all-wheel drive version with a motor of the same volume, but with a capacity of 280 hp.
• Yeti- on this model, the robot is available only with all-wheel drive and a 1.8-liter petrol engine with 152 hp.

Volkswagen

The German automaker has a wide list of DSG 6 models that can be bought in Russia in 2018, these include:

• Caddy- a compact van, which is not so often found on the roads of our country, the reason for this is the rather high cost, although the car is excellent. On this model, the 6-speed gearbox is available with a 2.0 liter 140 horsepower diesel engine and all-wheel drive.
• Caddy maxi- as you might guess from the name, this is an oversized version of the German compact van, the robot is also available here with a 2.0 diesel engine and all-wheel drive.
• Passat and Passat Variant- unfortunately, only variants with front-wheel drive and a 2.0-liter diesel engine with a capacity of 150 hp reached the Russian market.
• Tiguan- the second generation of the popular crossover has a wider list of variations compared to the first generation, on which the DSG-6 is installed. Basically it is a 1.4 liter engine with a capacity of 125 to 150 hp, and there is also a choice of front or all-wheel drive.

Pros and cons

Let's start with the merits:

• gear shift speed. The robotic transmission clicks gears much faster than the average driver. There are a huge number of videos on the Internet where they test the acceleration of identical cars, only gearboxes differing and, as practice shows, a car with DSG always accelerates faster than a car with a manual transmission;
• the second advantage of a modern gearbox can be considered smooth acceleration, due to the lack of sensations from gear shifting:
• fuel consumption is much lower than that of a standard machine, and the mechanics are inferior, although it all depends on the experience of the driver.

Disadvantages most often complained about by owners in 2018

• some owners are not satisfied with the fact that in a traffic jam they have to switch the selector to position N (netral):
• rumors of unreliability. With excellent potential of the car, sometimes you want to press the gas pedal and leave with a whistle from the traffic light, but it can be scary for the transmission, because to extend its life, it is better to start smoothly, and then, starting from the second gear, you can press down the gas;
• the cost of repairs and components, compared to mechanics.

Reliability, how are things in 2018?

The question of reliability is perhaps the main fear that stops many when purchasing cars from the VAG concern. The issue of reliability and negative reviews about the robot began to appear on the forums and on the network only after the appearance of the seven-speed DSG-7 robot with a dry clutch on the market, while cars with a “wet”, which did not cause any complaints, were sold on the market for a long time. Practice shows that the DQ250 is able to retreat about 150,000 km without any problems, provided it is properly operated and properly maintained. Car owners who buy new cars do not have to worry about anything. the warranty will allow you to correct defects without question with the help of a dealer. But when buying a car in the secondary market, it is better to diagnose the DSG 6 box, and then service it by replacing consumables and oil.

Reliability is evidenced by the fact that even on sports models, such as, for example, the Skoda Octavia RS, the transmission does not break down even on runs of 100,000 km. And this is worth a lot, tk. I operate this kind of cars quite tough and often go to the tracks.

Owner reviews 2018

We talked with the owners of cars equipped with this gearbox and here's what we got to find out

Vitaly owner of Volkswagen Passat CC

I really like the way this car looks. Prior to that, he owned a pre-styling version of the Passat SS with a 1.8 liter engine and a seven-speed robot, unfortunately I had to sell it. ... I decided to buy a restyled version with a 2.0 liter engine and a "wet" DSG, which I do not regret, because for three years of operation, the box did not cause any problems.

Toha owner of Skoda Octavia RS A7

I chose between the Audi A4 with a 2.0 liter engine, the Volkswagen Golf GTI and the Octavia RS itself, settled on the latter because of the price-to-size ratio of the car. What can I say I am completely satisfied with the car and the gearbox, I skated on the stock for a year, then I did Stage 1. At the moment, the mileage is 42,000 km, I am thinking about making Stage 2.

Kirill (Bravo_77) owner of Skoda Yeti

The second car was bought for pokatushek not new. I was looking for Seat Freetrack for a long time. Due to the presence of all-wheel drive and the correct DSG, but not finding a copy in an acceptable condition for a reasonable price, I decided to take the Yeti, although it is slightly inferior in terms of engine volume, but it looks much better in design. At the moment, the car has Stage 3, more than 320 hp. and a reinforced transmission. I do not regret thrashing the car all the time since lunch, while changing the oil in the box every 15,000 km, pouring oil from Vagovsk. At the moment, the mileage of 78,000 km, the Karabas is holding on confidently.

Ilya Alexandrovich owner of Volkswagen Tiguan

Tiguan was bought new in Rolf, which I can say I liked the car externally, and in the cabin there is a nice design plus a lot of space. Of course, I wanted to take a 2.0 liter with a seven-speed robot, which is installed on Audi, but unfortunately finances allowed only 1.4 150 forces and DSG 6. At the moment, the mileage is 17 400 km and this is what I can say, thanks to the fast operation of the gearbox and turbocharging, the engine's low capacity is not it is felt, for city driving it is enough for the eyes. Regarding the gearbox, I can say the following - the speeds change quickly and smoothly, before that I had an Outlander with a CVT and a Camry with an automatic transmission, so the DSG robot impressed me more, so in the future if I choose a new car, it will definitely be equipped with a DSG ...

We hope in the article we were able to answer all your questions about the reliability, resource and pros and cons of the gearbox, and also give an answer - is it worth buying a car equipped with a DSG 6 robot in 2018.

26.07.2017

Manufacturers of modern cars are constantly improving their vehicles. New technologies appear, machines become powerful. The improvement has also touched on gearboxes. Like its predecessors, the checkpoint has advantages and disadvantages. We will help you clarify the causes of the DSG 7 box problems. You can see more information in the video at the end. Let us tell you what are the disadvantages of the DSG-7 gearbox.

What is included in an automated transmission? The mechanism consists of:

• Mechatronic (control system);
• multi-plate clutch;
• primary and secondary pulley;
• main building.

The operation of the box is directly carried out by the mechatronic system. This device consists of:

• Holla sensor;
• electrohydraulic control system;
• a large number of wires;
• a mechanism for performing driver tasks.

DSG 7 works according to certain principles. To switch the car to high or low speed, the on-board computer automatically disconnects the clutch flywheel disc. The required speed turns on, the disk is automatically connected to the system. The main feature of this box is that it minimizes the time spent when changing gears.

Now let's take a closer look at why the mechanism needs two clutches? The first clutch dsg 7 is responsible for shifting odd speeds, and the second for shifting even. When the car starts to go to the flywheel, the disc of the first clutch is attached, and the second is disengaged at this time. When the laptop picks up speed, it signals the system and the clutches change.

Compared to the DSG 6, the improved version has a dry clutch dsg 7, which is installed on cars with a less powerful engine. Replacement of the dsg clutch is carried out by qualified specialists. On the Internet, there are many myths about a robotic checkpoint. Some car enthusiasts read about the advantages, while others read about the disadvantages. But it is not able to accurately form the advantages and disadvantages. We will show you find out the most famous advantages and disadvantages of this model.

Pros of the device

Based on many years of experience, it turns out that the box has many disadvantages and few advantages. Although there are few pluses, they are available. Let's consider the most relevant ones.

First, fast gear shifting. This is the main positive side of the portable mechanism.

Secondly, thanks to the mechanism, the driver can choose to control the speeds on his own or trust the system.

The big plus is the low absorption of the engine fluid. Unlike DSG 6, the new version consumes 5 times less engine oil. In addition, fuel consumption is 15% less.

Cons of the device

The downside is that when you buy a car with such a system, you never know how long it will last. Based on all the information, we have selected several problems that 85% of motorists face:

• During a gear change, the car may emit small vibrations or swaying (This is observed due to the presence of a dry clutch);
• vehicles with built-in DSG 7 are prohibited from towing. Towing can severely damage the clutch and break belts. Replacing the dsg clutch will cost a round sum. This means, if the car stalls, you need to call a tow truck. If you try to start yourself there is a chance to severely damage the car;
• the mechanism is not installed on vehicles with a longitudinal motor;
• extraneous sounds under the hood while driving. Typically, such sounds are heard by motorists when driving over a lying policeman;
• Due to the complex design of the dsg 7 mechatronics, few craftsmen take on the job. This is due to the fact that our specialists have little experience with such a system. Automatic transmission repair takes a lot of time and good equipment. Therefore, not every master will want to take up work at his own peril and risk;
• troubleshooting costs a lot of money;
• under heavy loads, the mechanism overheats. This is a big disadvantage for motorists who are often in traffic jams or travel long distances. During long-term operation, the robot overheats and begins to function inhibited;
• the clutch breaks frequently. A common problem if the car drives off-road or bad roads. Volkswagen dsg 7 manufacturers warn their users that the mechanism is not designed for constant off-road driving. Therefore, the device is best used in urban areas;
• dry clutch. Because of this, the machine wears out quickly. Due to incorrect algorithms of the mechatronics dsg 7, the machine does not function properly. Shaft bushings, pads, forks wear out quickly. The car has to be repaired frequently, and automatic transmission repairs cost a lot of money;
• dirt adheres to the sensor. Sensors are malfunctioning. The laptop does not see all the problems. Because of this, there may be frequent breakdowns of the machine. When the sensor is dirty, the device may not indicate that the machine is overheated, as a result of which an important part may burn out. Deep repairs to dsg 7 may be required, which costs a lot of money. In addition, not every auto repair shop will want to repair the DSG 7 device.
• mixing antifreeze with oil. The problem is very rare. Because of such a problem, you will have to do a complete replacement of the dsg 7. When the coolant enters the oil, the device breaks down and becomes faulty. The motorist may not immediately notice this problem and continue to operate the car. This will lead to very bad consequences;
• Holla sensors. We have already mentioned them above. According to the drivers, the device repeatedly cut off the traction if the Hall sensor did not work. The mechanism monitors the location of the gearshift lever. If it malfunctions, incorrect information pops up on the display. The equipment is out of order, replacement of dsg 7 is required;
• double drum clutch and flywheel. With the advent of this mechanism, the bearings began to wear out heavily. The clutch is constantly breaking for this reason. If metal dust enters the gearbox, the device fails. It damages the system. Need constant repair dsg 7.

From the advantages and disadvantages we have listed, it is noticeable that there are much more disadvantages than advantages. This is primarily due to the complex mechanism of the design. There are flaws in it that disable the car. The developers are trying to fix all the problems. Maybe soon the device will get better. In the meantime, the device functions as before.
