Just a note, the new pulley measured in at 71mm while the old measured in at 72mm. That could simply be within the manufacturer's tolerances or some sort of expansion of the old pulley due to heat or age. I replacing mine with this. The end results will be the same I'm sure, but it looks like part# 11281440237 was only used from 09/01/2003 — 04/20/2006, the more recent BMW/INA part number is 11287549557. Thanks and updated.
It's funny, the documentation online states it is 70mm diameter. I would love to save some money on it but want to make sure it is the same. I think when the time comes I will buy an OEM assembly and measure it .
