Files not found

Method: OBD / Recovery: Bench

Issue: The user is unable to perform an OBD read because the software version matches a file that has not yet been indexed on our server.

Solution
  • Switch your connection method from OBD to BENCH mode.
  • Perform a full physical read of the ECU on the bench.
  • Export the resulting file and send it to our team.
  • Contact our technical support at support@bflash.eu with the file so we can add it to our server for future OBD availability.
To understand more

Virtual reading relies on a pre-existing database of original files linked to specific ID strings. If your software version is new or rare, the tool cannot find a match; providing a Bench read allows us to map the memory and update the server for you and other users.
