HHTWIN and Xentry and DAS are all belong to the xentry mercedes star diagnose software.Many client want to know that what is the difference and what module does hhtwin support? Here ,OBD2repair.com share you what is the difference among star diagnose  HHTWIN and Xentry and DAS.


Star diagnose Software HHT-WIN vs Xentry vs DAS:


Xentry took me to DAS, and DAS switched over (automatically) to good old HHT-WIN, again. Guess my 16-year old SUV’s system is a bit ancient in the scheme of Mercedes-Benz technology.

From what I’ve seen:


All MB from late 80’s to 99 = HHT-WIN

All MB from 2001 to 2009 = DAS

All MB from 2010+ = Xentry


The year 2000 is a weird transition period — some MB made in 1999 but the model year is 2000 will be diagnosed from the 38-pin under the hood and thus use HHTwin. Other MB made in early 2000 and sold as a 2000 model will have the OBD port and the SDS will require the OBD cable to diagnosis….and will use DAS.


And then there are orphan cars, like some SLK models — some 2000-2001 SLK require the 38-pin.


I’ve even seen a 2000 E320 that had both 38-pin and OBD port — I could use either port to conduct a full diagnosis. That was funny.


Star Diagnose HHTWIN supports modules on Mercedes vehicles:


HHTWIN should be able to read all Modules.

Having said that, for Model Years 1990 – 12/1993, the Roadster Soft Top Module has 30 possible fault codes associated with it.
Whereas for Model Years 1/1994 – 1996, the Roadster Soft Top Module has only 11 possible fault codes associated with it.



IMPORTANT: HHTWIN is updated to 2018.9 star diagnose software disk. Software released in 2017 and 2018 doesn’t come with HTTWIN. But now, it comes again!
