    I believe bacteria builds up in the air con system. You could change the pollen filter and also try using something like this...

    TBH its usually a bacterial smell, so try the comma, if not then audi have a system, basically like a fumigator where they stick aircon on recirc & leave it running for little while to try & clear out the smell/bacteria present.
