Mercedes-Benz VGSNAG2 (7G-Tronic) TCU Flashing by DTS Monaco

 

Today we’re going to flash a VGS/NAG2 board inside Benz W221 gearbox by VXDIAG VCX SE and DTS Monaco.

Here we connect it to PC by VXDIAG VCX SE. (A good alternative that has a built-in DOIP: MB SD C4 Plus/Super MB Pro M6)
Besides, don’t forget gearbox 7-G renew cable and 12V power supply.

We run DTS Monaco, because DAS will ask for a password(have to calculate the password when the board turns to ECU mode through DAS).
On Temporary workspace, open up CBF file.
