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.

Now we’re going to unlock the board on Flash Programming.
Select CFF file.

Now go to “Variant Coding” to encode the board.
Connect ECU and select domain.
Here we’ve already written the coding.

Disconnect ECU and exit.

So, as you can see, we’ve flashed Benz W221 gearbox through DTS Monaco without any block or password required.
