At the beginning of the 2000s, Audi and Volkswagen cars had an unusual box [/desc] DSG7, which combined fuel economy and continuous power transmission. And despite these advantages, car owners are increasingly making a choice in favor of cars with conventional automatic machines, referring to the fact that the DSG7 quickly becomes unusable, it cannot be called reliable enough
Features of the DSG7 gearbox
The special design of the preselective box smoothly switched gears, thereby relieving the driver of uncomfortable jerks. Fully automatic transmission control allowed the electronics to track the vehicle's speed and the nearest gears, preparing for the next high without disrupting the flow of power.
At first, the DSG7 gearbox was greeted with applause - the car owners were delighted, in various articles the journalists described all the advantages of this automatic transmission. The advantages of the innovative design were obvious: reduced fuel consumption, the car ran smoothly without jerking when shifting gears. However, even this technology after some time revealed significant disadvantages.
Disadvantages of DSG7
The main disadvantage of DSG7 is strong vibration. And it was felt in various operating modes of the engine and transmission, regardless of the speed (both high and low) and operating modes, and even when the stage was turned on. Later, the cause of the breakdown was revealed. It turned out to be the wrong work of the mechatronics (you can say the "heart" and "brain" of the box). The saddest thing is that it is almost impossible to eliminate this, and the manufacturing plant did not attribute such transmission vibrations to warranty cases. The owners of these cars had no choice but to put up with this drawback. In addition to the pronounced vibration, this robotic transmission also did not have good reliability. What was the reason? This automatic transmission belongs to the group of automatic transmissions in which a very small amount of oil is used (so to speak, a gearbox with a dry clutch), which leads to overheating, frequent and rapid wear and other serious problems.
The previous generation of DSG6 gearboxes needed to be equipped with 4.5 liters of transmission fluid for efficient operation, while for the DSG7 it was enough to fill in only 2 liters. Accordingly, the automatic transmission at high speeds gave frequent slippage and overheated. In the future, this led to costly repairs. And the masters involved in transmission repairs also confirm the unreliability of the DSG7 box, in comparison with the previous generation of automatic transmissions.
Recommendations for car owners
Dynamic driving with strong acceleration and hard braking is bad for this gearbox. To extend the life cycle of mechatronics, it is necessary to protect the preselective automatic transmission, to exclude active acceleration, sharp acceleration and deceleration. Smooth driving is recommended. This rule is true even for powerful cars. The average car owner is probably better off not messing with the DSG7 box. Despite the outstanding advantages of this design, we recommend choosing either time-tested mechanics or simple standard machines. Otherwise, you should be prepared for malfunctions and even for serious repairs to the DSG7 box.
