Re: V6 Oil Filter numbers

["Craig D. Niederst" <niederst@telerama.com>]

I ordered 6 Mahle oil filters from Imparts a few months back for my '92 100.
I got the Audi P/N from TPC's webpage (034 115 561A), which according to
them is for the '91 200 20v, '92-'94 100 (AAH), '92-'94 S4, and the '95+ S6.
The filters that were sent to me were Mahle OC47, which is what the guy from
Imparts confirmed was the right filter for the AAH V6 (same as 034 115 561A
minus the rings). According to the info from Andrew's post, this is the
wrong filter. I'm using one of these filters on my car right now, and used
one for my previous oil change also (~5k miles total). Anyone else out there
with an AAH V6 using one of these OC47 filters? What is the major difference
between the OC47 and the OC154 filters? Could any damage to the engine could
have been caused by using the wrong filter for ~5k miles (used Castrol
Syntec 10W30 for both changes, not to start another oil thread :-) )? TIA.
