Well, in reviewing the list it looks like the valve cover seal is prone to =
failing covered by warranty.
The bypass valve are prone to tearing, both the old and new throttle body b=
oots are prone to tearing. Both of these falures can lead excessive air pre=
ssure loss causing the turbos to run too hard and fail.
I have not seen it on the list, but Anderson Motorsport has noted several c=
am seal failures which were covered under warranty.
I have seen some other issues like failing or leaking headlight washer pump=
. Draining batteries, premature failure of brak pads and or rotors, etc.
I have seen some of these problems discussed in an Audi Technical Service B=
ulletin (TSB). I am looking for a complete listing of the factory TSB's for=
 the a4/s4/2.7t. At one point someone had a web site with them and/or a res=
ource to subscrib to them (like a shop does). Anyone know of this now?

aware of any. Recalls - I have not received any recall notices of any
kind from Audi for my Mar 2001 date of mfr S4 Avant. What recalls are
you referring to? TSBs? These might be interesting.

2001 silver S4 Avant with 20,000 miles, stock, no problems whatsoever
that are not related to hitting deer or flying hunks of wood except a
coolant temperature sensor that went intermittent. Dealer replaced
without question under warranty.

Greetings

I am new to the biturboS4 list but a long time member of the Quattro and
Urq lists. Sadly I just sold my 84Urq (awesome car) and my first Audi,
90q20v, is also on the auction bock. Before I purchased my S4Avant new,
I owned a A430vAvant for a few years, as well. I have been off both for
a while so please excuse me for asking about something already covered.

Enough about me, on to the questions. In looking through the archives
briefly I see there are some pretty significant technical issues with
2=2E7t motor, as well as, other problems that are covered either under
warranty or via recall. I guess it would be a good idea to get all the
TSB's for the S4. Can anyone point me in the direction of a resource for
all the TSB's and recalls it need to be aware of.

Thanks
