I bought a 1995 S6 Avant a couple of days ago to replace my aging 80q.  What
a car!

The wastegate has a vacuum connection on the top.  Nothing is connected to
it (it's open to atmospheric pressure).  Is this right?  Do UK spec models
not bother with a wastegate frequency valve?

Is it possible to read fault codes using a LED on this car.  It has the
black and white two-pin connectors in the fusebox (+/-/K/L) as shown on
Scott Mockry's page, but I don't have access to a VAG1551.  There's a lot of
talk about VAG-COM.  Should I get one?

The engine appears to be functioning well - I've seen 2.1 on the boost gauge
a couple of times.

The oil temperature gauge has no illumination and no movement of the needle.
Are these faults related?

I've got (paper) Bentleys for my 80q and 100 2.2E.  How does the CD version
of the A6/S6 manual compare?
