Get ready for a major productivity boost this month. OBDSTAR is thrilled to announce a significant software update scheduled for release soon, bringing advanced Mercedes-Benz TCM solutions to the X300 Classic G3 and DC706.
This upcoming update will introduce a much-anticipated OBD/Bench mode virginization for both FBS3 and FBS4 Transmission Control Modules, offering a safer and more efficient alternative to traditional repair methods.
The End of “Open-Cover” Operations
For a long time, working on FBS4 (VGS4-0-NAG2) 7-speed TCM units has been a high-stakes task. Technicians often had to resort to destructive operations—cutting the module housing or performing complex soldering—to access the internal immobilizer data.
The new OBDSTAR solution changes the game:
- Non-Destructive: No more cutting or soldering.
- Safety First: Eliminate the risk of irreversible hardware damage and financial loss.
- Efficiency: Perform virginization directly via OBD or BENCH mode.
What to Expect: Key Support Functions
Once this update goes live later this month, users will be able to handle used MB TCUs with professional-grade precision:
- Virginization: Reset used modules to factory status for reuse.
- Personalization (Data Transfer): Seamlessly sync data between modules.
- VIN Writing: Update the vehicle identity within the software.
- Fast Turnaround: Complete the personalization after reading original vehicle ECU data—install and start the vehicle immediately without extra online programming.
Supported Hardware (Coming This Month)
| System | Transmission Model | Connection Mode |
|---|---|---|
| FBS3 | VGS2-NAG2 / VGS3-NAG2 | OBD / BENCH |
| FBS4 | VGS4-0-NAG2 (7-speed) | OBD / BENCH |

This update is designed to help professional workshops stay competitive by simplifying one of the most complex tasks in Mercedes-Benz maintenance. Keep your DC706 and KeyMaster G3 ready—the future of TCM servicing is just weeks away.
