After work on your maps using your favorite hex editor, if you still having trouble writing, you can use a needle to apply 12V directly to pin 43 of your ECU, then your MPPS will able to write. Never forget to check the checksums of the file you will write. MPPS do it reasonably well.
If you still not feel confident enough to make this procedures, post all ECU numbers and I try to send you one copy of you original BIN file.
Would you have an original file for M5.9.2 software 1037362228 and 06A906018FK by any chance? its on a 2003 Golf 2.0 8v
