66855200 ANTI POLLEN FILTER $104.07 from Ricambi
Found a Wix WP 9036 Filter for $7.86 plus $26.39 shipping from Rock Auto to replace it.
Filter is 252x216x32 as opposed to OEM 252x216x38 so it is a little thinner but it works.
I happened to have a Navistar Micron filter Part# IN9501P that I used to make up the difference but can work without it.
The filter is used on 2007 SKODA Roomster, VW Fox & Polo, Audi A2 & Mercedes G-Klass
The filter box has other filter makes cross #'s on it. (I did not try to see if they could be found locally)
To replace just remove trim panel under glove box & slide lock at filter housing & filter pulls out.
