MB Star C3
C3 is a diagnostic device that supports old cars from 1989 to 2015 with functions such as:
- Read and clear errors
- Read data from sensors
- Activate actuators
- Programming and coding ECU boxes on the car
If you regularly repair old Mercedes lines or trucks, MB Star C3 is a very good choice.
MB Star C4, C4 DOIP and MB Star C5
If you need a Mercedes star diagnostic too for both old and new models (1989-2022), you can choose MB Star C4, C4 Doip, or MB Star C5.

However, for new models from 2016 that need a standard Doip connection, MB SD CONNECT C4 DOIP is the best choice to use.
Mercedes star diagnostic tool C4 Doip is 1:1 compared to the genuine C4, but the price is only 1/10 of the original C4 but still has all the functions like the genuine C4. MB Star C4 DOIP is rated as the BEST CHOICE product in the segment of diagnostic equipment for Mercedes-Benz vehicles.
Both C4/C4 DOIP and C5 possess the same functions as MB Star C3.

MB Star C6 is an upgraded version of the previously released MB Star C4 and C5.
