It's  apparently the same filter that was used on the VW Rabbit diesel in the  early '80's - that's what it said on the box of the first one I bought  from the dealer. And it was actually only the first oil change interval  that was changed, starting with the 2004 models - 5k, 15k, 25k, 35k.  Those are the free changes under the Audi Advantage coverage, versus  10k, 20k, 30k, 40k for the previous B6 1.8T's. Hard to believe they  still recommend 10k intervals, even with synthetic oil.
  
  I am doing 5k intervals with the OEM filter and Mobil1 0w-40.
