Flex Read SID321 Failed KESS3 Success

By | February 6, 2026

Renault Continental SID321 reading review:
MMS Flex failed to read SID321 via OBD VR. It says no Virtual read available for this software version on the server.

Cannot do it on bench when no vr on server.

Did it with Alientech KESS3.

Autotuner will also do this ECU. AT is the best in this ecu.
