Device:MB STAR C3 multiplexer

Software: Xentry/DAS 2013.07

Model: Mercedes-Benz 221.156
The extra thing have to do is:

Then after installing new unit and transfer all data to it, next, go to:
Development Data ==> Control unit adaptation ==> Variant coding ==> F3

Then we chose from the list the same number we got in image below

First, you need to programming new vgs by Vediamo with hardwarewhich you have in your old VGS
Then you will have your variant of coding.
