Depends on the part and date of manufacture. For example, 32106857282 is on both models. Same with the variable unit 32106859248 - used on 320, 328 and 335. And both of these are quite new units.
Looks like there are a handful of different versions within each line, depending on date of manufacture. That may help explain some of the variations in opinion.
For the xDrive models, both the 328 and 335 use the same rack - 32106859273 for regular and 32106859274 for variable.
