Magic MotorSport Flex failed to read 2021 Opel Vivaro Delphi dcm7.1a ECU via OBD. Are these not able to be done?
Solution:
OBD is not the best solution for after 2021. 2022 onwards problem with obd.
Some users also reported they had problems with Flex on 2021 DCM7.1A OBD.
Do DCM7.1A in BOOT mode. Go for boot its more safe in DCM7.1A. Only do obd if you have a full boot backup. They can die obd mode. Sometimes they can be repaired boot mode, bit sometimes the eeprom data is destroyed.
Sometimes VR not available with flex then need boot. Or use other tool like Autotuner via obd.
Or open and boot with mms repair file and all OK again.
