Mercedes 7G-DCT dual-clutch gearbox control unit (TCU) cloning

Mercedes with a "Transmission fault. Visit workshop." message, jerking when pulling away, slipping between gears or no drive? If your 7G-DCT control unit (TCU, VGS2-FDCT) has failed, we clone your original unit's data onto a matching replacement unit so it works on your car without dealer coding.
