I've just had bad experiences with the used 1.8T A4 (B6) I bought last
April. Mahle filter is very similar to the Audi filter. (BTW make sure
you're getting the oversized filter for the turbo, part#068115561)
Here's a message I recently posted to Audifans:

Subject: Cut open my oil filter
(If someone would like to do this with a filter used for 5000 - 10000
on a clean 1.8T I'd love to see it.)
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.
(I cut it open using several of those cheap rotary tool cut-off wheels
Not much to it. A spring holds the core and gasket against the open end.
gasket seals the incoming oil from the flow out the center and keeps oil
from draining back into the pan when the engine is stopped. There is a
spring loaded gasket at the top that will allow oil to bypass clogged
if the pressure differential within the filter gets too high.
The filter paper stretched out (used a hand saw to cut it out):
This is 1400 miles since the cleanup. (I feel the TSB cuts corners, to do
right the head should probably be pulled and soaked in solvent instead of
scraped by hand in place)
Hopefully, next time this won't be so bad. It actually doesn't seem that
now considering the amount of crud I removed from the head.

I have absolutely no experience of Mahle filters but I know for a fact
that Mann manufactures the original filter that is mounted by Audi. If
you check an original filter you can see that it is really a rebranded
