Hi, i see a long time gone, but how you solve this problem, do you successfully cross-flashing 8D0907551 M-box file to 4Z7907551M? Because I'm thinking to do that on my 2002 Audi A6 6-speed 4B0907551AK but I'm afraid to brick the ecu. Thanks

Yes. As long as they are the same version (ME7.1 vs ME7.1.1) and the same flash size (512MB vs 1024MB) the 2.7t ecus are cross flashable.

if I had check summed the file properly im sure there would have been no issues.
I am currently running an s4 mbox so my abs/level controls are not happy.
this is was to be expected, you need to change the original file creating a definition for your file, you need to go this way the only way to succeed

write me in personal messages which maps and variables you need, since I sometimes have free time, I will try to create a definition file for your computer. The file will be available to everyone

"I bought used 4B0907551K ecu for tuning"
For you a6 K-box. Searched quickly so that errors are possible, check. Do not forget to recalculate the checksum. I attach ols file 4B0907551K.ols

for anyone curious as to how I solved this. the ecu soft coding was incorrect and I feel dumb.
ecu was coded as 06651 (non abs) whereas it needed to be 06751 (with abs)
thank you all
