Mercedes STAR Diagnostics

Mercedes STAR Diagnostics is a set of tools, that are used to completely read out Mercedes, Smart and other Mercedes brands. It is like VAG group VAG-COM for Mercedes.

There's a party that can ship SD Connect C4 clones, including all cables and required software, called Stardiag. As long as you chose the R170 car base in the software, you should be able to read out the whole car, except for the TPMS, because those are from Chrysler, not Mercedes.
