Volkswagen gearbox: its advantages, disadvantages and main problems (DSG)

The gearbox is a standard manual gearbox, it consists of 2 manual gearboxes that are installed together in one box and the output of it, as well as one output on one gear, each gear has four gears for speed, where the gears are placed on the gears of the even speeds, such as the second gear and the gears on it individual and background speed.
 The clutch assembly is designed with the same design as the normal clutch, which consists of two ball bearings, so that two clutches and two balls are on one cylinder, and the pedal is the same shape as the ordinary pedal, but the pedal is moved by oil pressure.
There is a mechatronic unit, which is composed of a control and an oil pedal for each clutch, and there is also a pedal for each speed in the place of the manual gearbox hand, in order to control the gear lever and select the speed like the manual. There is an oil cycle for each clutch, but it differs from the oil cycle in the manual.
Volkswagen said that the DSG Vitesse It is different from automatic transmission because it is based on a mechanical system similar to manual transmission.

Simple tips and steps to get the longest life

The company also said that the transmission needs to be treated differently to preserve it from damage and obtain the desired performance, and confirmed that by taking simple steps, the highest performance of the DSG transmission can be obtained and its lifespan increased through:

• On highways, the gearbox is set to automatic.
• On the roads with high traffic, the gear must be in the D position, with the driver still controlling the gear stick, whether + or -.
• In very crowded roads, the stick is moved to the STEP TRONIC system and it is treated as a manual gearbox and is treated on + only because the gear will change speed according to road conditions without using -.
• The process of converting the gearbox from the D mode to the STEP TRONIC mode does not require pressing the brakes.

Types of gears ( DSG )

• first type

It is a fully automatic gearbox and relies on a hydraulic system in the transmission process, and it was connected to a motor similar to the torque converter in the normal automatic gearbox, but it is two clutches that are installed inside a body and they are engaged by oil pressure.
Afattas is mounted like Afattas Alatomatik but by some and as we mentioned before that there Fétis marital speeds and Fétis individual speeds and background are Khrjhm on SHAFT and one calf.
And because the gearbox is automatic, it is completely immersed in oil and the gears in it are normal automatic gears, and VALVE BODY is installed from the top .

• second type

It is one of the most common types in Egypt, where it is found in many cars, and it consists of a manual gearbox completely unlike the first type, and it is made of separate units and grouped together, which made it distinguished by its genius design not because its idea is new and different, but because of its design that It is characterized by the ease and simplicity of its parts, and how distinctive and simple at the same time.
    Fuse problems

first type

One of the most common problems in this type is its high temperature, because there is one oil cycle for the gearbox and hydraulic control, as it is the same oil used, and because the gear is of high performance, this caused pressure on it and made the clutches heated. 

second type

The problems of this type are less than the problems of the first type, because each part is independent, but the problem is that not all problems are known because it is new in the market and among the most famous problems so far:

• First: There are very few problems with the manual gearbox, the most famous of which is corrosion.
• Second: The defects of the regular brackets, but what increases the problem is that it has 2 clutches and they are transported at a high speed, in addition to the vibration that people feel when making shifts in speed.
• Third: The mechatronic unit is very complex, in addition to the solenoid valve that is pressing on the clutch pedal is very sensitive to malfunctions, and these malfunctions have not been tested.
