What is the MB SD C4 Plus — and what is it for?
The MB SD Connect C4 Plus Star Diagnosis is the official diagnostic interface for all Mercedes-Benz vehicles manufactured from 1996 onwards — passenger cars, trucks, vans, and commercial vehicles. With WLAN wireless connectivity, it eliminates cables between the interface and the technician's computer during diagnosis.
With the SD C4 Plus, technicians can access all electronic modules of the vehicle — engine, transmission, ABS, airbags, comfort systems, and others — and can perform fault readings, coding, parameter adjustments, and ECU reprogramming without needing to disassemble components.
ECM Tech Center sells and provides technical support for the MB SD C4 Plus. Please contact us before purchasing to confirm compatibility with your vehicle model.
