How To program transmission control module New VGS W204?

VGS fails due to many reasons and needs to be replaced. When replacing, it is necessary to use diagnostic software and specialized equipment to synchronize with the main control box (TCM reprogramming). In this article, we will show you how to code and program the new VGS in the most detail. Now let’s find out!

Why is it necessary to program transmission control module?

When replacing any module on the vehicle, it is necessary to program transmission control module or reprogramming TCM. Because only then can the new module, once replaced, operate stably and synchronously with the vehicle.
Transmission control module (VGS) is known as the part that controls different gears by collecting and processing data through sensors, it will determine when and how the user makes gear changes. Mercedes VGS directly interferes with the vehicle’s motion system, so it is necessary to reprogram it so that it can operate effectively on the vehicle.
If you don’t know how to program it, see the steps below.`

Transmission control module programming tool

You need to prepare the following devices and software to perform coding and programming:

Specialized computer

You should use a laptop with the following configuration i5 3rd generation, Ram 4GB or more, Hard drive SSD256 or more, Windows 10/11

It is recommended to use a well-configured computer to use diagnostic software. You can refer to some of the most used computer lines by technicians today: Panasonic CF-19, Panasonic CF-53, Panasonic toughbook CF-54,… There are also many other computer lines that you can use.

Specialized software for Mercedes-Benz:

  • Vediamo coding software changes features, integrate new parts into the car, activates 360 cameras, speakers, screens, … accurate and best Mercedes-Benz car. To perform coding for new car models, you need to use DTS Monaco 9.02. In this article our technicians are using Vediamo.
  • Xentry Openshell: a diagnostic software that reads and fixes errors specialized in Mercedes-Benz. Depending on the connected device you use, choose the appropriate Xentry software. When using DOIP devices, you need to use Xentry Openshell, if using J2534 devices, you need to use Mercedes Xentry Passthru software.

Specialized programming tool

You can use the specialized diagnostic equipment you have. However, we recommend using the C4 Doip device, which is the most stable device to use today. In addition, you can use other DOIP devices such as C5, C6, M6,… capable of working with Mercedes coding software.


Specialized diagnostic equipment MB SD CONNECT C4 DOIP has the most stable diagnostic features, error correction method, lookup, and programming coding.
SD Connect C4 is a device capable of stable connection with specialized Mercedes software. Additionally you can use other devices on the market that are capable of working with Mercedes software.
