Mike,
Bosch like any other transnational concern has branches the world over.
Their oil filters are reasonably good coz at least they have antidrain
valves, unlike Fram and the like.

I would still stick with the Audi filters (or Mahle or Mann - the OEM
vendors for such).
A few years ago I bought 2 cases from my Audi dealer for $110 (they were
on sale at $5.50/ea) since all my cars use the same oil filter, even the
long gone VW Fox. At this price it didn't make much sence to buy Bosch
filters at $5/ea. from my local imports supply.

Definitely stay with the OEM filters for a turbo engine (no suffix in
the p/n). I've been told that they have a unique opening and bypass
pressure setting. I.e. the ones with a suffix "G" (non-turbo 5cyl) and
the ones with the "A" (6 cyl) have different values for the said
pressures.
Although all three types are exactly the same in dimensions and thread
size.
