Problem: It’s a VW Polo 6R with Delphi DCM3.7 engine control unit ECU. No programmer seems to be able to read this ECU via pinouts (bench). Foxflash, KESS etc should read this ECU via OBD, but the ECU was removed from car. So tried to read ecu using the  Godiag GT100 breakout box  via OBD on bench. But FOXFLASH didn’t read the flash. Then tried to read this ECU with Scanmatic + pcmflash. Have managed to read it using the Godiag ECU box but cannot write it any further.  There’s no problem reading, but writing is still impossible. OBDSTAR DC706  doesn’t support this ECU, and  XHorse MultiPROG  doesn’t support this ECU for the VW Polo either. both devices support the same DCM3.7 for, for example, Kia/Hyundai/Sunyung, etc). If it works via OBD in the car, why doesn’t it work on the bench using ECUBOX? The ECU is identified but reading or writing isn’t possible? Any solution? Solution: It’s because immo is active, obd reading for that ecu requires immo to...
