I don't have a picture, but during an oil change back in early december on my 2014 VW Jetta with the 1.8L turbo engine, i pulled out the STP S11784 cellulose media cartridge filter from the housing to see that it gone from the usual cylinder shape to an hourglass like figure. Oil used during that OCI was 6qts Mobil 1 FS HM 5w30 (this was before i realized the engine needed oil meeting VW 502.00) I am curious as to why the filter took this shape. My hypothesis is short tripping without an occasional long drive to remove moisture from the oil caused the cellulose media to deform. Anyone have any other possible ideas why this happened?

Common complaint on German Car Forums that not OEM filters for German cars collapse, tear, twist, are not the correct length. Stick to Mann, Mahle, Hengst, or Purflux. I've had failures of aftermarket filters in VWs, Mercedes, and two different BMWs.
Yeah after i pulled out the S11784, in went a microgard select MSL10396, which held up much better, but i might have to take advantage of AAP's oil change bundle for the next oil change because those Mann filters aren't cheap!
ahh nevermind i just remembered you can only get CQ filters in their bundle deal
Can't buy only the filter? Seems odd.ahh nevermind i just remembered you can only get CQ filters in their bundle deal
You can, but 16 USD is pretty steep for a Mann HU6013Z
