How to Repair and Test Volkswagen 7-speed Transmission Mechatronics?

What is DSG Transmission?

DSG transmission is an advanced technology that VW introduced to the automotive industry in 2003. VW is the first to introduce DSG and uses it most in its own vehicles. DSG transmission is known by everyone in the automotive industry, as VW is a pioneer in this regard.

DSG gearbox is more advantageous than other gearboxes due to the convenience in gear shifts and the savings it provides in fuel. Due to these advantages, other vehicle companies use this technology under different names.

DSG gearbox has 2 gear groups. These are 6 forward and 7 forward gears. Transmissions with 6-speed gears are oily, while 7-speed transmissions have dry clutches.

In order to test the malfunctions that may occur in the DSG Transmission, the DSG Transmission Tester has been produced by Nitro Mechatronics. The Tester consists of 3 parts. The first is the main body with the gear group. Although not very often, this body can also malfunction. The malfunction can be detected when the gearbox is disassembled and checked. When the fault is detected, the problem can usually be fixed, it is not necessary to replace the gearbox completely. The second is the group with the gear separation mechanism. In case of any malfunction, the clutch system is renewed and it is made usable again after the gear adaptation is made. The last one is the Mechanical unit. The fault mostly occurs in this part. Card failure, hydraulic body failure, solenoid valve failures may occur.

Today, the 7-speed DSG gearbox is widely used. So, let’s first examine what the 7-speed DSG means.

What does 7 speed DSG mean?

The dual-clutch DSG transmission is an automatic transmission that can change gears faster than other gear transmissions. In addition, the dual-clutch transmission provides more power and better control than conventional automatic and manual transmission systems.

The 7-speed DSG gearbox is the gearbox that has been gaining in popularity recently. The 7-speed gearbox was developed to replace the 6-speed gearbox, and it quickly became widespread and its usage area expanded.

The 6-speed gearbox is in a single-chamber state, that is, all parts in the DSG use a common oil. The worst part of this situation is that when any part of the transmission becomes dirty, it also affects other parts of the transmission. Therefore, some changes have been made in the 7-speed DSG gearbox in order to provide better efficiency and weight savings compared to previous models.
