VGS stands for fully integrated transmission control unit. It is a type of automatic transmission control unit that is used in some Mercedes-Benz vehicles. The VGS / NAG2 (7G-Tronic) is a single unit that controls all aspects of the transmission, including gear selection, shift timing, and torque converter lockup.

The VGS was first introduced in 2003 in the Mercedes-Benz 7G-Tronic automatic transmission. It has since been used in a variety of other Mercedes-Benz vehicles, including the C-Class, E-Class, S-Class, and CLS-Class.

The VGS has a number of advantages over traditional automatic transmission control units. It is more compact and efficient, and it can be more easily updated with new software. The VGS also allows for more precise control of the transmission, which can improve fuel economy and performance.

Here are some of the problems that can occur with VGS transmissions:

  • Faulty VGS unit: This can cause the transmission to malfunction, such as shifting erratically or not shifting at all.
  • Faulty sensors: The VGS unit relies on a number of sensors to operate properly. If one of these sensors fails, it can cause the transmission to malfunction.
  • Mechanical problems: The VGS unit is a complex piece of machinery, and it is susceptible to mechanical problems. These problems can be caused by wear and tear, or by abuse.

Tuning VGS/7G-Tronic Transmission

Tuning a VGS transmission is the process of modifying the software of the VGS unit to improve its performance. This can be done to increase the speed of gear changes, improve fuel economy, or make the transmission more responsive.

There are a few different ways to tune a VGS transmission. One way is to use a software tune, which modifies the firmware of the VGS unit. This can be done by a qualified Quantum Tuning dealer outlet.

Another way to tune a VGS transmission is to use hardware modifications, such as installing a performance clutch or a different VGS unit. Hardware modifications can be more expensive than software tunes, but they can also provide more significant performance improvements.

If you are considering tuning your VGS transmission, it is important to do your research and choose a reputable tuner. It is also important to understand the risks involved in tuning a transmission, as it can void the warranty and lead to premature wear and tear.

Here are some of the benefits of tuning a VGS transmission:

  • Faster gear changes
  • Improved fuel economy
  • More responsive transmission
  • Enhanced driving experience

It is important to choose a tuner who has experience tuning cars with your specific make and model. They should also be able to provide you with a warranty on their work.

Here are some of the things to ask a tuner before tuning your VGS transmission:

  • What kind of tune do they offer for my car?
  • What are the benefits of their tune?
  • What are the risks of their tune?
  • Do they offer a warranty on their work?
