Why MB Star C3 Xentry cannot work on W205 recent Mercedes

User puzzles:

I have installed Xentry 9.2014 in Benz 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 SD Compact 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.Mercedes 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 MB 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

Some reviews on 07.2017 DAS Xentry, hope it helps!

This version is mostly the same like previous, some more protection and redesign.

The same bugs with this version, possible it’s normal according to Daimler opinion:
–StartKeyCenter doesn`t not show key validation dates. Any key. But Xentry understands validation dates perfectly.
–AddOnCenter doesn`t close to a tray, if it was once opened, it stays at the taskbar always. Then a problem with a computer Shut down.

Changelogs were renewed.
“The XENTRY Diagnosis Software from Youobd2 has undergone a redesign. A Help Card with details can be found in the Support Tool.”

DAS 7.7.2.1 version like in 2016.07.
Limitations for Old keys:
StartKeyCenter limitation for DAS.
DAS License.0 limitation.
2221-XX limitation.
3.91 limitation.
MUX FW update is not needed from the version 2015.09 to 2017.07

1.What is possible to make, beginning from the worst.
2.Stupid files replacing is still possible to fix 2221 and 3.91 errors with loosing a hell of Java instructions for Old keys. Now it looks like foolish game with a simple illusion in the end.
3.Another way was tried just for fun. It`s possible to safe all Java instructions for Old keys with decoding and native Java code rewriting/fixing. Native DAS is possible to start with the same license parameters like it was with Old DAS keys and Old DAS license key is absolutely not needed in the system at all. Protection could be fully disabled by now.
4.“Original” keys.

There is a new not activated protection in a code with this version. Better to say 2 variants, but mostly the similar.
