The new Mercedes Benz diagnostic tool MB SD Connect C5 is verified working great. Here are customer feedback to Benz C5.
SD Connect (not original Xentry Connect C5).

1.“Mercedes Sprinter year 2006 and 2014 works, both thediagnosis. All the personal cars also works, no problem”

2.“All the trucks including euro6 also works, no problem. Bus Mercedes Tourismo euro5 year 2010-2012 test works, BUT year 2014 euro6 does NOT work, it says that the license is invalid. Both sd c4 and sd c5, we have tested both on the same cars, to be sure.”

3.“SD Connect C5 this one customer has test, works good, in function it no difference with SD C4, but performance it is better. So you can buy MB SD C5 if you want buy new MUX. SD C5 use the same software as MB SD Connect C4.

4.“I have used V2016.12 software. I am ready to order the new 2017.05V software. It is said that the 2017.05 DAS/Xentry has improved a lot. New software in SSD runs faster and much more steable on Windows 7 or Windows 8 instead of Windows XP system. Also, new WIS and EPC parts catalog offers more full information for more models.
Well, my friend with 2016.12 version saying earlier Daimler AG needs the user name and password to login, but in this version, no need that.”
