RE: Oil for turbocharger

[Bill Samaras DTN 223-7322 29-Jun-1993 0808 <samaras@wrksys.enet.dec.com>]

All of the "normal" Audi turbo's have only one oil filter.  All 5000 CS turbo
quattro's ('86 on) and 5000 CS turbos (at least from 1985) have just a single
oil filter design (as well as everything after that).   If you go looking for
another oil filter, you just won't find one.

The $original$ Audi quattro coupe did have 2 oil filters. But as far as I can
tell, this was the only application of 2 oil filters.

The Bently manual for the 5000 (T, Q, etc.), doesn't mention anything about a 
second turbo oil filter. All of the mechanical discussions and diagrams clearly
show the single oil filter design for all turbos (even Diesel versions).

Since I own (and have done tons of work) on an 86 5000CS TQ, I can testify that
there is one and only one oil filter. (There is an impressive oil COOLER
though).

By the way, the Bently manual is worth every penny. There is information
contained that is just not documented anywhere else. It has saved me its cost
many times.  If you really want the inside scoop, subscribe to Audi's service
bulletins.  I have all of them for the 5000. I think the cost was $12.  They
are organized by section, and match the Bently manual format.
