I finally got around to replacing the cabin air filter. You need to have done this at least once, so the next time will be *much* easier! This is a job on the official maintenance schedule for 15K miles.
The OEM unit is part number 9171756, the replacement unit is 9204626 on the box and (I realize belatedly) something different on the actual filter (seems to me it was a 6-digit number, beginning 15xxxx).
The "story" here is that the unit from the factory was more than 50% thicker in section and of *much* heavier material - looks like it might be charcoal impregnated in aid of odor control. The "official" Volvo replacement is rather flimsy, by comparison.
Has anyone else replaced the unit and noted this difference? Comments?
