User puzzles:
I have installed Xentry 9.2014 in Mb Star C3 multiplexer. It works well so far. Now, I need to make diagnosis on mercedes w205 year 12/2014 but It can not communicate with the car. C3 don’t work in all recent cars in xentry but in DAS is ok.

Experienced users’ suggestion:
C3 has many limitation regarding latest vehicles in Xentry.
It can’t diagnose it e.g w205, w212, w222, w906, smart 453 etc.

its glory is already passed unless you deal only with vehicles in DAS.
you have to change to Mb Star Connect C4.
C4’s support also officially has been stop since 12-2015.

It is no different even you change folder.
it is different protocol with recent vehicles.

For your w205 (nice car) you can use one of this :
1.sd connect c4
2.xentry sd connect BENZ C5

Both good at all new Mercedes Benz models,W222, W221, W212, W203, 211,W 204,W207, W212, GL166, B 246, CLS 218, SLK172 and Smart405, 451, 452, 454

Besides the Star Diagnosis software c3 and c4 own, sdconnect c4/c5 added three more software: SD Media, Xentry and Smart TAN Code.
SD Media: Video and PDF lessons;
Xentry: New software released by Benz Company after 04/2009 by diagnosis new cars. Xentry software for diagnosing W 204,W207 and W212 which C3 and C4 does not support;
Smart TAN Code: Opened special function in DAS program with Smart cars 405/ 451/452/ 454.Besides, it also opened more special functions, such as engineer mode, remove limitations,etc, which Star C3 and Star C4 do not have.

I have successfully communicated wit my w205 AMG using a MB SD C4 connect all controllers accessed.
