Mercedes VGS Coding

Masters at VGS Coding

Is your Mercedes experiencing transmission problems, like limp mode, rough shifting, or incorrect gear selection? It might be an issue with the VGS (Vehicle Gear Shift) module or conductor plate within the 7G Tronic transmission.

Carkey Masters offers specialized VGS coding services to address these common issues, restoring your transmission’s smooth and efficient performance. Our process involves:

  • VGS Reflashing: If your VGS module’s software is corrupted or outdated, we can reflash it with the latest, error-free software to restore proper functionality. This process involves updating the module’s internal code using specialized tools and software.
  • VGS Coding (New or Replacement): If your VGS module is damaged beyond repair, we can source and install a new or used (donor) VGS unit. We then perform expert coding to match the new module to your specific vehicle, ensuring seamless communication with the transmission control unit (TCU).

Diagnosis

Symptoms

  • Transmission Warning Light: The transmission warning light on the dashboard illuminates.
  • Limp Mode: The transmission goes into “limp mode,” limiting gear selection and speed to protect the transmission.
  • Rough Shifting: Gear shifts become harsh, jerky, or delayed.
  • No Gear Engagement: The transmission may not engage any gear, or it might get stuck in a particular gear.
  • Delayed Engagement: There might be a noticeable delay when shifting between gears.
  • Transmission Fluid Leaks: In some cases, a failed conductor plate can cause fluid leaks.

Error Codes

  • 0717: The signal from component Y3/8n1 (turbine speed sensor, VGS) is not available.
  • 0718: The component Y3/8n1 (turbine speed sensor, VGS) is defective.
  • 0722: Output speed sensor Y3/8n3 output speed sensor VGS not available.
  • 2201: The component Y3/8n2 (internal speed sensor) is defective.
  • 0721: The transmission output speed signal is implausible compared to the wheel RPM signal.

Important Note: These are just some of the common symptoms and error codes. The specific issues and codes can vary depending on the model and year of your Mercedes-Benz. It’s crucial to have your vehicle diagnosed by a qualified technician to determine the exact cause of the problem and the appropriate solution.
