How to Use PCMTuner Read and Write VAG DQ200 DQ250

Question: I can’t read VAG DQ200 Gearbox TCU with pcm tuner. Why do I have gray buttons when reading and writing? Have the same problem with DQ250.

Solution: If you read via OBD, you can only read VR, need to identify and request a file. If you read on the bank, you can read and write EEPROM and flash. Use the pinout module 58 in the file area. Do not use colors shown in diagram, use pcmtuner cables with names.
