Hi!
scn is only relevant for engine and tranny, as far as I know. When we deal with SAMs
and other stuff, its better to use star, I have to say (at least for now). Try to search
through benzworld forum for < variant coding > topic within xentry developer mode.
Maybe this will help. Unfortunately I'm not a pro in car diagnostics : I just bought tools
to play with my own 55amg, which was bought for fun too, cause here in russia the
winter is too long :-) . To calibrate/encode SAM you need to go into developer mode
and then into variant coding. Once more : benzworld forum is just a place with a good
and well informed people... try to find the answers there!
