I bought an Audi A5 which was already remapped but is not a very good tune so I would like to find the original file but there are different 6 digit 'software' numbers. How do I find out which one my car originally came with from factory?

VCDS log:

Which 6 digit number do i go for?

8K0907401 0012 this is your software number

VCDS log suggests 8K0907401 0012 which is '510328' but the label on the ECU reads 8K0907401 0008 which is '390626'

Does that mean I have the wrong software file on my ecu?
