i pulled this file from a car that magically stopped running and it had a checksum error fault code so i check the checksum ME7check and it says the RSA cant be corrected. anyone know of a why to make it correct? it came from an automatc 2004 jetta 1.8T. File in question is attached.

Did you bother trying ME7Sum? If not, why not?

Does the file have AL/NLS?

Nothing but a lot of prok zero'd

yes i did try ME7sum and no it doesnt have any of the add on's because it came from an automatic car.

And? Where is the output? Please don't beg for somebody ELSE to do checksums for you without letting somebody teach you to do it yourself.

Here's the output from ME7sum.

Attempting to open firmware file '06A906032NL.bin'

Step #1: Reading ROM info ..
 Searching for EPK signature...OK
 Searching for ECUID table...OK
 EPK         : '42/1/ME7.5/120/4013.00//24D/Dst03o/110303/'

So tell ME7Sum to output a corrected file.
