Today I find MB Star Compact 4 is no more an unusual transportation, the auto vehicle develops at a high speed, and new version comes out continuously. Therefore, new version 2013.03 the diagnostic needs to update with the speed of new MB star series.
The version is the lately updated professional diagnostic equipment for car. When new version comes out; it means the old version was kicked out. This obd2 tool is not only support K line diagnoses and CAN BUS, but also UDS diagnose protocol. Because old MB Star Compact 4 main board do not have UDS chip, so old version cannot support it. It also can support multi-language, such as English, German, French, Italian, Spain, Portugal, Finland, Denmark, Sweden and so on.
MB STAR C4 not only can support wireless diagnose, but also support K line, CAN BUS and UDS protocol, fit all computers, with multi-language. It is enough to replace the old version. You can try to use it.
