Charcoal filters . . . there's two!

As I recall, the pre-filter get serviced at 90K or 100K miles. But don't recall seeing anything about the main filter.

Just changed my S500 charcoal filters (95K miles); the pre-filter, which is easy, cost about $100.

And the main filter. This is difficult to get out. Cost also about $100.

But no stink! The prefilter was very WET because the air plenum drain hose got diverted and drained into the the pre-filter cavity. It had a damp smell but was not detectable in the car.

Good luck, it's a job.
