I see this type of question alot. You'll notice only the last number is different.
The first number means "up to" #12-013742, so that's #12-000001 through #12-013742, the second number means "as of" #12-013743, so #12-013743 and higher numbers.

If you're lucky, if can find your warranty booklet for the car, on the last page is this glued on blue "Warrtungsheft" or warranty sheet, which will have your engine number on it, if you look it over carefully, it will begin 103.940, and a few more numbers, then you'll see the 12-XXXXXX, those last 6 you need to know.
