LAUNCH X431

 Through collaborations with various manufacturers, the LAUNCH X431 diagnostic tool supports access to various vehicle gateways, such as VAG SGW, FCA SGW, Renault SGW, and more. It is worth noting that recently (May 25, 2026), the Volkswagen Group (VAG) has introduced updated security protocols for accessing and unlocking protected vehicle functions via SFD (Vehicle Diagnostic Protection).

 This procedure resets a Mercedes-Benz VGS3 / NAG2 (7G-Tronic EGS) transmission control unit using the LAUNCH X431 PRO5 on a bench setup. The goal is simple: clear anti-theft personalization, return the TCU to a neutral state, and prepare it for reuse or programming. The job must be done outside the vehicle with stable power and correct pinout wiring — no shortcuts. Workshop Reality Check (Before You Start) In real workshop conditions, this job fails for three reasons: Wrong pinout on VGS3 bench wiring Unstable power supply during erase Losing connection mid-process (internet or CAN drop) If any of these happen, the module can become unresponsive. Set up properly first, then start the software. Required Setup Tool: LAUNCH X431 PRO V Module: Mercedes-Benz VGS3 / NAG2 TCU (EGS 7G) Mode: Bench only (module removed from vehicle) Power: Stable 12V regulated supply (do not rely on battery) Network: Stable internet (required for anti-theft function) Wiring: Correct EGS...
