The file you posted has quite a lot of differences between it and the stock A4TF300F file......do you know what was done to the ECU?

Strange. I've double checked it again and attached. This is the modified file that you posted.

If it still fails then i'm missing something here....

I was doing a HEX search for 030037 030038 and 030139 after scanning the other threads on openec covering this topic and then inserting 050000 over those locations to disable the CEL. Sometimes I found duplicates elsewhere but the correct offsets are usually bunched together at the end of the file at 0x0001... or 0x0002...
