I think it is under the glovebox but there is no cover like in the 2009. To the left on the centre consol there is a cover that could be the cabin filter but I am just guessing and want to know for sure before I start removing parts.

If that is the location this particular piece has no torx screws ...

Looks like Volvo has changed the position of the cabin filter on the 2010 S80.
Need advice on location and how to replace it.
