there are different ver of the motor which one is mine

 

well i know its pgm so that narrows it down to A5 A4 A7 and A8 but the A7 was only in europe so it down to 4 5 and 8

 

I'm going to go out on a limb here, but its possible that your engine is simply a Japanese engine that replaced the original. In the other H/F engines the 'A' designated it as a JDM, 'A1' indicated USDM.
I think the '1908757' corresponds to the vehicle VIN code.
