Short answer: Yes it does.I guess the real question should be does it work on vehicles newer the 2014. I hope somebody has an answer.
Long answer: There's some caveat though. If the software that's on the car is newer than the Xentry, there's a good 50% chance that it might not be able to read it (ie. error out or say no communication).
FWIW, I had no problem connecting to 2012, 2013 and 2014 MB with 9/2011 Xentry on my laptop.
I've since then upgraded it to 3/2015, but that was only to enable online programming.
And yes, there is a workaround to get online with cloned SDS C4 and program using the latest files from MB, but it's difficult.
