[A4] Cut open my oil filter

The car is running well. The pressure hasn't dropped off since cleaning the engine and installing the new oil pump and screen. I've strained and reused the oil a couple of times before this oil and filter change after 1400 miles to ensure that the screen doesn't become clogged again by the remaining sludge.


a link on oil filter analysis that I just found:

    Here's the innards of the Mahle filter I just took off my A4 1.8T with the 
    sludge problem (for a refresher: the problem arose under Audi care -- 
    original filter spec and dino oil as Audi had not yet switched their 
    specs -- at the second oil change which was 12471 miles after the first). 
    Inside of the engine has been cleaned according to the Audi Sludge TSB.

  Interesting - but kind of hard to tell if it looks good or bad by a picture... And actually, having never seen the innards of an oil filter (used) before, I probably couldn't even tell if I saw it in person!

  How is the car running now?
