Question:
Multi Prog ECU Programmer won’t read Mercedes W169 EIS. I didn’t do any of them, I did 10 of them, none of them worked, and in one of them, W203 only read flash in EIS, but not eeprom.
Here Xhorsevvdi tech support answer:
Wrong Connection.
Double check pinouts in Multi Prog software.
*If the tool still fails, export the diagnostic report and send it and SN number to your seller.
Done!
