2009 OBXT, 69k, Just bought it a couple months ago.
Threw a P0011 code over the weekend. Limped it home, drained oil, did a heartland flush (with new oil filter), drained/threw away the filter then filled up synthetic and new filter. Unplugged battery overnight and code was gone. Drove it for a few days and no code.
Then last night, went in and cleaned the OCV on the driver side (it was fine) and removed the passenger side banjo. The EXTERIOR of the filter looked decent, but after removing you could see that the INTERIOR was gunked up.....over 60%. Ripped that B*tch out and car runs great. Turbo even sounds better.
Long story short, get rid of the screens, may look fine on the outside but in, not so much. FWIW, it's a circular screen, so there are 2 filters (essentially) that the oil has to pass through.
Next up, passenger banjo.
