Based on your VIN, your build date is 8/2014…and the shafts are different lengths. The left side is slightly shorter than the right side. I don’t know if there’s a difference, but since they have RHD (right hand drive) models in Europe…if shopping on that side of the pond, make sure they are searching for a LHD f15 X5.
The left shaft shaft (#1) is 698mm and the right shaft (#2) is 1011mm. There appears to be multiple 11 digit part nbrs that are compatible/exchangeble…just be sure to search using any of the correct part nbrs based on which side axle you need and production date info.
