I will go ahead and post up the 2006 M instructions here. Changing the micro-filter is recommended at every 15k miles.
The overall procedure (from the FSM, section ATC-134) is:
1. Remove glove box.2. Remove filter cover, and then remove in-cabin micro-filter.3. Take out in-cabin micro-filter from blower unit.4. Replace with new one and reinstall on blower unit.5. Reinstall glove box.
The glove box is removed as described in the picture I will attach momentarily to this post.
