DSG DQ250 clone issue.

[Bmwpower530]

Hello everyone, i need to clone DSG DQ250 tcu, first i read both tcu ori and spare, ori is 2010 (file size 1.46mb), spare 2005 (file size 448kb). I can't write ori tcu file to spare tcu cause i getting incorect file size error. Maybe someone know answer why Kess read different file size.

Give thanks to lord program was intelligent enough not to allow you to write that file, or you would have faced heavy paperweight.

To "clone" you need proper tools + same part numbers...

Yes we all know buy original, proper tools. Not always tool is issue. In my case Hw numbers of TCU's is the same just last letter different.

So isnt same...

Maybe that last letter is very important maybe not. Local tcu repair service always says give us black (old)tcu and wewill clone it from white(never) tcu. Maybe this time is exception. We learning everyday what we dont know.
