Changed the oil on the '08 Beetle 2.5l. Oil change interval was 8014 miles with Delo 5w40 Syn and a Champ filter. This is what the filter looked like when it was done. It is a little bit deformed, and it *almost* looks like some of the filter media is being sucked in or pushed into the filter cage on the inside. I am not familiar with VW's and just wondering if this is anything to worry about, and if so, what is going on?
