I just drove the X5 down to florida and back which is 13 hours each way. The sport seats just don't fit me quite right and it wound up killing my right shoulder - that's not to say they're bad seats, they're just not good seats for me specifically. After doing some research, it seemed like the comfort seats would drop in and they did. Everything seems to work without coding except heat distribution (can adjust where the heat goes from butt to back) without any coding at all! If anyone else is looking to swap the same seats, I can at least tell you it works.
On a side note, if anyone is looking for sport seats in gray (LUAD upholstery code) in the mid-atlantic region, PM me. My old seats look like they've had a repair but are in pretty good shape. I don't want to ship them and they're just taking up space.
