Ok, first here is a picture of my 04' split front fender. (Very good explanation provided by simoncpw btw...)



And here is my sticker on the door right UNDER the tire pressure sticker... My X3 was built in 03/04 = March 2004. And thus falls into the 10/03 - 08/04 04' MY category. If your X3 was built in 09/04 and onwards it would be an 05' or 06'.



You really are making this a lot harder then it needs to be...
