Hi all, would someone be willing to have a look at my flash file for validity?   I have read my 2001 Allroad 2.7t tip 4Z7907551K using Nefmoto v1.9.3.2 and a original Hex+CAN in dumb mode using memory layout 29F800BB and it saves the file without reporting errors.  However when I test the file with ME7check v1.12 it reports a checksum error.  I have not attempted to edit it yet, I wanted to be sure I had a good read.   I did try a  second read and compared the 2 files with tuner pro compare function and it found no differences.  I was able to read  another 2001 allroad today using the same equipment and its bin file checks fine.  I have attached the bin that fails(Andyallrd2nndreead.bin) and the one that reads no errors(Muiralrd800BB.bin). 

Here is the output of Me7check and me7sum:

Any advice would be appreciated.   Apologies for the long post, hope this is the right forum to start in.
