If you are going to buy or already you are the owner of a car with a robotic preselative PPP DSG. or S-TronicThat, for sure, already persistent about the different sides of these aggregates, both positive and negative. It is impossible to definitely say that DSG. - Evil and it is necessary to avoid cars with this type of checkpoint.
DSG (from it. DirektschaltGetriebee or eng. Direct Shift Gearbox) - a family of preselective robotic transmissions with double clutches installed on Cars of Concern Vag (Audi, Volkswagen, Skoda, Seat). In general understanding, users are accustomed to sharing these boxes on 6-speed (DSG6) and 7-speed (DSG7), as well as on gearbox with dry and wet clutches. The classification is generally true, but there are a number of nuances that should be considered when choosing a car, since not everything is as easy as it may seem.
How is S-Tronic Audi different from DSG Volkswagen / Skoda / SEAT? - Nothing, with the exception of longitudinally located boxes 0B5, 0CK / 0CL and 0CJ, which are installed only on AUDI.
Also you could hear the scary word of mechatronic (Mechatronic) is the same hydraulicone. What are mechatronics and what do they differ? Mechatronics is an electron-hydraulic control unit of the KP. Perhaps the most important, but at the same time the most unreliable knot throughout the transmission. Each DSG type has its own type of mechatronics. Mechatronics from different types of DSG are not interchangeable. Moreover, for some types of DSG there are several generations of mechatronics, which also differ from each other. And for each type and generation of mechatronics, there are many versions of software designed for various engines and different gear ratios in KP. In some cases, the mechatronics of the same type can be reprogrammed (reflash) to install on different cars.
An unambiguous answer to this question, which DSG is more reliable - does not exist. Each DSG has its advantages and disadvantages. The duration of "life" of any DSG in most part depends on the conditions of its operation: all DSG do not like overheating, it usually concerns a DSG with "dry" clutches in which the mechatronics has a separate oil circuit and no cooling. For those who every day for several hours spend in traffic jams, the chances of coming to replace the mechatronics more than those who are mainly driving on the highway. Fans "light", the probability of replacing the clutch and differential, is much higher than those who prefer a quiet ride.

In order for you to understand how often what oil and in which volume it is necessary to fill in the DSG (S-Tronic), we led to the table below:
| DSG model | Oil in the gearbox itself | Extra oil | Replacement |
|---|---|---|---|
DSG-7. | Butter G 052 512. | oil in mechatronics |
Today, large automakers are increasingly equipping new models of their auto preselective checkpits.
Gradually, the "robot" with two clutches becomes the usual attribute of a premium configuration.
What is the difference between the S-Tronic from the DSG - marketing stroke or different aggregates?
However, Volkswagen and Audi are allocated from the general list - they first went on this path, starting the massive application of preselers in the early 2000s.
The transmission, installed on the Volkswagen machines, received the name DSG (abbreviation from Direct Shift Gearbox).
The invention Audi was represented by the world called S-Tronic.
As you know, both of these companies are divisions of the concern VAG. Given this "kinship" and the simultaneous output of the RCPP, it can be assumed that the developments were conducted together. Confirms this guess and the fact that DSG and S-Tronic does not have obvious structural or technological differences.
Moreover, there is an opinion that the s-bronix is \u200b\u200brebranding DSG.
However, everything is not so obvious. The snag lies in the layout of the motor, which, in the case of Audi, rather non-standard.
A huge part of cars from the Audi model range is distinguished by the longitudinal location of the engine.
As for most passenger cars, including the battle of Volkswagen - there the motor is placed transversely.
All generations and modifications of DSG are also calculated on the transverse layout.
At this stage, it becomes clear what the S-Tronic differs from the DSG.
With Iron confidence you can say that certain changes and improvements of Audi accurately had to make.
Unique modifications of S-Tronic are installed on all all-wheel drive and some front-wheel drive models.
You can distinguish such aggregates by factory label - DL382 and DL501. For service notation, indices are commonly used: 0B5, 0CK, 0CL, 0CJ.
The Volkswagen concern began its work on the creation of preselective automatic checkpoints in the first half of the 80s of the last century. In 2002, the developed box of S -tronic with a pair of clutch debuted in serial production. During this time, this unit is significantly improved and improved, and even its new generations due to a long periodically, qualified repair and maintenance (for example) are required. About what features s -tronic and the reviews of the owners of the car with it, we will talk more.
Concept and design preselective boxes
Any transmissions are characterized by certain strengths and weaknesses. The main minus of the classic "automaton" is the opening of power during the transition from one transmission to another. To eliminate this deficiency, auto industry representatives are developing upgraded automatic transmission, where transmission change is possible without this opening (rupture). This led to the appearance of preselective boxes.
Their idea is quite simple. As a basis for creating the work of the manual transmission with a pair of shafts. In fact, this box has two clips, allowing to exclude the power break during transition between the transmissions. This decision not only helped to increase dynamic characteristics, reduce gasoline consumption and / or diesel engine, but also improve the safety of the car during overtaking and the implementation of other maneuvers at speed.
Today, 7-speed preselective robotic boxes are put on AUDI brand cars, which are called S -tronic. This unit has proven itself in the market, is considered reliable, technological and such that contributes to increased comfort when driving a car.
Compact sizes
One of the strengths of preselective 7-speed boxes created by the Volkswagen concern are relatively small overall dimensions of the aggregate. Due to this feature, this robotic checkpoint can be applied on compact vehicles that differ in limited subcarrane space. That is why S -tronic is in demand today and in various small car cars, where the installation of a full six or seven-step "automaton" is extremely difficult.
Thus, in the urban compact car of the Audi brand, thanks to the development of a preselative unit, it became possible to use multistage automatic transmission or RCPP, which contributes to the implementation of the dynamic potential of the engine, and the efficiency of fuel consumption, and increased safety.
How does s -tronic work?
Constructively, this development of the Volkswagen concern is closer to the mechanical CAT, which are equipped with a robot - an automatic device switching steps. In vehicles with S -tronic, it is assumed to use stealless "petals" (switches for manual shift), although it is quite effectively coping with the tasks and automatic mode. The process and automatic, and manual switching takes the fraction of a second, and the power loss does not occur, as two clutches are involved.
The 7-speed S -Tronic box for Audi is characterized by the presence of a computer control system that tracks all transmission operation parameters. If any problem occurs, for example, fails, the computer will display a warning to the dashboard. Thanks to this feature, the operation of the car is not only simplified and the driver's comfort increases, but it also appears to respond to breakage and reduce the cost of maintenance and / or repair of the aggregate.
Modern diagnostic equipment used in service centers also contributes to rapid definition of malfunction and its elimination, if the problem warning is generally common (there is a warning from a transmission computer, but without concretizing the reasons).
Another specific feature of this preselective box is to ensure greater maneuverability when turning. In maneuvers to the right, the cooking increases due to the compression of friction packets, and when turning to the left, a hydraulic engine is locked, which gives the right wheel an increased torque.
Reliability level S -tronic
With all the advantages of this box "AUTOMAT" for Audi cars, the minuses of the unit also have, we should consider the owners of a car with such a transmission. First of all, this automatic transmission has a complicated design, which allows you to achieve a smooth transition between speeds without jerks and gaps in power. To do this, there are additional clutches and shafts. An increase in the number of rolling parts leads to an increase in the risk of breakage even, despite the fact that all elements are made of durable and reliable materials.
The second important feature of the 7-speed box is an urgent need for timely qualified service. So, first of all, the unit requires a regular replacement of oil, which is worth performing every 40-50 thousand mg of mileage. Ignoring this recommendation and the desire to save on service as a result will turn into additional costs - probably it will be necessary or fails. S -tronic box is demanding and to the type of oil - only original brands are recommended.
Another specific feature of this box is constructive differences from classic "automata". Because of this, a number of specialists and masters of car services are not taken for working with this unit, which should also be taken into account by potential buyers of auto audi with this automatic transmission.
As is known, in the line of the German manufacturer of Audi, the Audi Q5 SUV, the main components of which are borrowed from AUDI A4 '08, were added to the Audi QUTTRO AUDI QUATTRO models. The new sports SUV AUDI Q5 combines all the road car with the dynamics of sports sedan. The superiority of the high Audi technologies, allowed to provide the Q5 SUV, all the necessary nodes and units, for example, as: a practical chassis, a powerful engine, 7-speed automatic transmission (ACP) with a double friction clutch S Tronic and a dynamic AUDI dynamics system Drive Select, magnificent design, high-quality finishing materials, taste and comfort of the cabin. All this together is taken, create a sporting SUV excellent opportunities for traffic in the city and off-road, providing the necessary comfort for their owners during any ride. But the most important component between the engine and the car became precisely equipped with a S-Tronic box.
Today we will talk in detail about the 7-speed automatic transmissions (ACP) with a double-friction clutch S TRONIC in combination with Quattro drive, working paired with a gasoline-liter turbocharged engine Turbo FSI, with a capacity of 211 horsepower. The ACP has a TRONIC trade name and the service designation 0B5. The TRONIC ACP is a completely synchronized KP with electro-hydraulic control, provides automatic gear shift without breaking power flow, with very short switching times and continuous thrust, gives considerable fuel savings and pleasure when driving.
Why we decided to pay attention to this model of the gearbox, everything is very simple, it is almost perfect in terms of dynamics, sportiness and results.
The overall results of the clutch reaction in various modes have almost enormous indicators, and in Dynamic mode is achieved in just 79.893 miles.
S-Tronic gearbox has proven itself as the fastest and successful Audi car transmission. This gearbox is installed almost on all all-wheel drive models of the German brand, which requires high gear shift speed and instant response to changing driving style.
The TRONIC ABP has a range of gear ratios for gasoline engines 6, for diesel 8, while the seventh gear is increasing, and the maximum speed is achieved on the 6th gear. The automatic box provides up to 550 nm at 9000 rpm, the mass is about 142 kg with a two-headed flywheel and oil filled.
Now we draw your attention to the constructive feature of the gearbox. The TRONIC ABP consists of two main parts. The first part includes: a leading disk, two-volume flywheel, main transmission differentials, two multi-disc friction clutches with electro-hydraulic control, couplings are cooled with oil using an ATF inner pump, a MEChatronik block, a fitting for connecting an ATF radiator, oil sapuans. Viewing and learning everything in detail, we mark that the Mechatronik block includes a hydraulic system control unit, an electronic control unit, a part of temperature sensors and actuators. The second part is a mechanical part or seven stepped fully synchronized gearbox (seven stepped variator), which has an independent lubricant system, inter-sieve differential, oil collectors, gear lever, side shaft, drainage. Everything is formed in such a way that it creates a balance between the ACP agriculture, its cooling and the highest speed of the gear shift reaction.
The S-Tronic gearbox has proven itself as the fastest and successful transmission of Audi cars. This gearbox is installed almost on all all-wheel drive models of the German brand, which requires high gear shift speed and instant response to changing driving style.
For example, the Audi R8 sports car is equipped with a double-seized S-Tronic transmission, as well as all known "charged" models Audi RS.
Paying more attention to the Audi R8 sports car, equipped with a new S Tronic, one can noted the property of this box - it "jumps over" between the transmissions, which gives an incredible dynamics when pressed on the gas pedal. Audi cars with such a gearbox "shoot" from space with an amazing power.
Audi R8 with a 5.2 liter engine installed under the hood, accelerates from 0 to 100 km / h in just 3.5 seconds. But, despite its power, the car manages to save fuel. At the moment when the driver releases the gas pedal, the TRONIC box switches to the last 7th gear, which significantly saves fuel. According to the manufacturer, the average fuel consumption of a sports car dropped by 1 liter per 100 kilometers of the way.
1. Special oil collectors for directional lubrication of bearings and gears allow you to work at a very low level of oil. This reduces the breakdown losses (bubble), which improves (bubble), which improves efficiency.The torque margin is about 350 nm, ideally suitable 2.0 l TFSI and 2.0 l TDI engines.

Next, in the materials we will describe in detail about temperature sensors, hydraulic pressure sensors, gear shift sensors, primary shaft speed sensors, about the cooling and gearbox protection system, about the correct operation of the ACP S Tronic and many other things.
Many manufacturers, and Audi is not an exception, since the beginning of the 2000s, in pursuit of economy began to move on alternative gearboxes. Fortunately, automatic transmission options have become more, because before alternative to the hydrotransformer in mass production no longer had anymore. And, by and large, no matter how much you "shoved" into a regular automatic gear, it will be more voracious than a variator or robot - well, the efficiency is such, nothing can be done.
Audi, following the example of competitors, transferred part of its cars to Multitronic variators. And it would seem that Panacea. After all, it is obvious that the technically variator (CVT) is somewhat simpler than the machines came across the transmissions and gears. In addition, Multitronic favorably differed from an outdated box with its economy. There were almost everything in win. But, as time has shown, the variator had a number of constructive problems that were difficult to treat improvements, so a few years later, Audi began to look for an alternative to Multitronic.
What did the Multitronic Variator please? Advantages and disadvantages of the variator
At first everything was very different. Smooth change in the transfer ratio, in which the connection is not broken between the engine and the leading wheels. The moment on the wheels is passed continuously. It is pleasant in operation, and even economically, at least somewhat unusual. But the main disadvantage for the variator was the tendency to overheating. Especially, given that the variasts have equipped almost all possible crossovers, in which sooner or later they drive into the dirt or try to ride in a snowy virgin. In addition, the variators do not like a big torque. And for premium cars, with powerful motors, this is already a big problem. Currently, the variators rarely meet on cars with a motor volume greater than 2 liters. There are, of course, rare cases as at Subarovsk Lineartronic, for example, but it is greater as exceptions.
There are no roads. Only s-tronic robot
It was not hurry to return back to the hydrotransformer in Audi, so I had to use the developments of Volkswagen engineers. Instead of variators began to equip their cars innovative, at that time, gearboxes S-Tronic. In fact, these are traditional Volkswagen DSG, only named by the exclusive name "S-Tronic". In Audi, they like to personalize themselves a little - TFSI instead of TSI, S-Troni instead of DSG. About robots with double adhesion from Volkswagen (DSG) said already, probably, everything. Especially about versions with dry clutches, seven gears. We only add that problems with the reliability of the PPC during the transition from the variator on the robots did not leave, they simply changed.
But still someone from this won. The buyer received a cool gearbox capable of giving pleasure from driving, from switching speed, and the manufacturer reduced costs, because these boxes are installed on all models of the VAG concern, which naturally reduces costs. True, when you have to repair a DSG, and this is not uncommon, even despite the constant modernization, it has to be pretty spent.
