Hello,
have destroyed my ECU via OBD. It can not be read and write.
It also can not flash in boot mode. (GallettoV53 and V54).
When it was still ok, it did not work also with boot mode. It could only be read.
The memory I have now unsoldered (ST M29F400BB) and read out (GQ-3X).

When I open the file in WinOLS, a message appears (the eprom contents should have been imported with the line swapping Vag Simos3. Would you like to apply this swapping now?).
And then opens the file correctly.
How do I then save the correct file? So I can write the file back with the GQ-3X?

thanks
Daniel

Ask an expert to help you, or find the file on your computer

when you export the file from winols before save it where you want unswap it...then you can flash it
