So, I ran the me7check.exe against daz's bin that I was using, and it came out ok:
ME7Check v1.12 (c) mki, 06/2004-05/2012
Checking file 551M Bosch.bin (size=1048576)
Reading Version Strings...
-> Bootrom Version = embedded in CPU, asume 05.12/05.32
-> EPK = 40/1/ME7.1/5/6005.01//22m/DstC2o/011200//
-> Contents of ECUID data table:
- '0261207143' (SSECUHN)
- '1037360857' (SSECUSN)
- '8D0907551M ' (VAG part number)
- '0002' (VAG sw number)
- '2.7l V6/5VT ' (engine id)
-> Contents of ECUID data table:
- 'HW_MAN004'
-> No errors found. File is OK. *********************
But when I ran it against me7sum it failed in the same way that my bin failed, something I might have overlooked previously:
*** Found 73 checksums in 551M Bosch.bin
*** ABORTING! 64 uncorrectable error(s) in 551M Bosch.bin! ***
I have not had any problems with the car starting or driving, granted I have unplugged the battery terminal right now as I'm working on some fan wiring. I drove it for approx 2 hours on Wednesday night without issues.
