I have read the file from my 01 allroad.  It completes the read and I save the file.

When I check the checksum with ME7Check I always get 1 error.  I have read the data several times using different speed settings and always get the same error.

Am I doing something wrong?

Microsoft Windows [Version 6.1.7601]

This is the file I read from my car, stock file.  

Why am I getting a check sum error?  

I am trying to learn what I am doing wrong, should this not give me a valid good checksum?

Attached is the file

Did you bother comparing it to the stock bin I linked above?

If you did, you'd notice your file is not stock.

I really thought it was a stock cpu, my apologies.  I was more focused on the checksum error in the read process.

I am trying to learn and right now things are in a spinning vortex that I am trying to grasp.

DD,

What did you do to be able to see that info you posted, did you convert it from binary?  Or a particular program?

Thanks for your help

It's the signature from the file. Open it with a hex editor. Unfortunately, that is all you will learn from looking at that file. It is encrypted like all APR tech. I am surprised your car still starts/runs after reading that. Must be old APR.

found it FEFA0, thanks. 

Grabbing a few more things out of the vortex  Grin

Now I can stop beating my head on the dash as to why I was not getting a valid checksum.
