I have the same noise...think it was caused by using a non-Audi oil filter
(one without a check valve in it).

Tried running Syntec and Slik50...doesn't help.  I've gone back to regular oil
because I can't justify the high cost of synthetic in a non-turbo car.

Again...I have the same problem.  I think Glen Powell said (hope I'm right
here, Glen) that either ignore it or replace the lifters...but it will probably
just come back in time.

I'm kindof saving up for it, cause when I do it, I want to have the head
reworked, put in a more agressive cam, etc.  I'll be putting some messages out
to the list when the time comes.  ;-)

It's lifter noise from the hydraulics...not much you can do except replace
them I understand.  Perhaps there's an oil-pressure regulator that's
malfunctioning???  I had one on my Datsun...basically a needle and seat valve
with a calibrated spring in it.  Do these exist on Audis?
