Yes, but watch out for that parts site, I've used it many times since the previous link to ETKA disappeared, that oemepc one is missing bits here and there, you don't notice it until you end up getting annoyed about not being able to find the part you need! Also, it currently is not up to date.
Edit:- also the general plan was to try to avoid buying parts from Audi when the exact same part is available elsewhere, in this case from ECP if you buy the Mann version, or even better buy the more modern next generation from Mann which is the Frecious one now under £15 it seems - a bargain? I like to stick what the manufacturer uses as much as possible, but with a pollen filter, when the same is cheaper elsewhere were is the problem, and add to that being able to buy a more advanced version that so far Audi has not started to use - even better?
Another Edit:- are you sure that the part number you quoted is correct, is that not just for the plain/basic filter, these cars tend to get the carbon coated one fitted as it kills odours better, its part part is 8K0 819 439B ? (I know that VW fit the basic filter on fixed price servicing, which is naughty!)
