I have bought Mb star c3 from china, it work well on some model of mercedes, not good on others.
I want to repair it by my self, need somme assistance from you please.

-The value of real voltage displayed on top right of DAS screen was 20-30 volts (real value must be 12 volts).

-while quick test on the model w203 and w230 the das can't comunicate with ezs, it display "!'.
-under xentry, impossible to connect to w204.
-never tested on other mb w212.

I tested my das on vito, sprinter worked well!!!!

baked one tranzistor with nuber TIP42C end one resistor 330om insaid in multiplexer ....have bad heatsinks...if you WANT to SEE to cook more quickly, connect the 24volt.
