When I replaced the clutch cable of my LS I measured its total length and ordered the "right one" from MAX. The "right one" came witht eh right overall dimensions and with BMW signs all over it but it seemed longer than the old one; hard to adjust for freeplay.
Another critical measurement that one needs to be aware of is the fully extended length of the bare part of the cable from the end of the housing. It appears there are variances in that length. I was able to adjust the new cable but it was near the max extension.
So, morale of the story, look for the total length of the cable and what is the measured length of the extended, "naked" part of the cable to ensure you have the right cable.
Suerte,
