I check the archives every time before I post... except this one time.

But what Bob says isn't quite right. The Bentley clearly shows on page
17.7 that there are two filters. But he does appear to ultimately be
right about the presence of the extra filter.

***Bentley aggravation flame-on***

People rave about the Bentley manual. But Bentley did not have one for
the old 100LS series. I asked the dealer parts manager if he could 
get me a copy of _THE_ factory workshop manual, the same one the
service department had, complete with the TSBs. It was a 2-volume
loose-leaf manual that came in grey vinyl 3-ring binders with the
PORSCHE+AUDI logo on them. COMPLETE with a full-color electrical
chart for the 73, 74, 75, and 76/77 model years. All models year
variations were shown. The translation from German to English was
pretty bad, but it was good enough to get the job done.

However, the Bentley is almost as bad as the Haynes as far as 
showing model & year variations. I want a manual that covers
_MY_ car!

For example, the Bentley shows _nothing_ about the rear differential
except how to remove/install it and change the seals. Big deal.
What hav I got to do? Buy the manual for the VW Illtis?

***Bentley aggravation flame-off***

But the Bentleys are still better than Chilton/Clymers and similar
old books, although I think they may have given up covering Audis after
the 100LS.

> My conclusion is, it's likely still an MC. 

Yeah, I guess I was needlesely freaking out, but I wasn't going to
let this stop me from changing the oil, _especially_ since Phil
seems to think I ran my Q's rear differential dry.

Thanks, Bob!
