Vw Golf R 7.5 DQ381 problem

Hi everyone, I hope someone can help me find the solution to my problem.


Then, after writing the mod file via obd of the gearbox in question, DQ381, the car does not start and the gearbox control unit no longer communicates in obd, it should be noted that by connecting to bench I can read and write all the contents, flash and eeprom. Apparently the bdm part of the file was lost.... Can anyone help me reconstruct the file or maybe if there is a different solution. Thanks a lot to everyone

You need full backup of your SW version to bring CAN stack back - then immo fix/removal if needed. Post ID details.
