Buy the Bentley CD - if you check the AudiWorld website - you should find a
vendor or individual willing to sell a copy. The Bentley CD has detailed
schematics of the S4 engine bay, electrical components, body, etc. This
should be your first stop - then look for the online short cut versions
(aand compare for accuracy). At least with the Bentley CD, you will have the
authorized (by AOA) schematics of  the S4, grabbing someone's DIY schema
from the NET is taking a big risk, you DON'T know what might have been LEFT
OUT (only to find out that it was important!).

I had wondered about this.

Every audi tech at the shop I worked at, with the exception for me, tried
1 time and exactly once to replace the turbos without removing the engine
on an S4. These were very rare occurances, so everyone got suckered into
it at least once without realizing they shouldn't do it.

It really can't be done. The most you end up with are turbos that leak
because you can't torque any of the plumbing pieces to it to spec, and ...
I mean. I've done it on an engine stand 5' below the car with everything
out, and it was STILL incredibly difficult. Even when you're staring at
them, there is just no room to get at anything.

Honestly, it's not that hard to take the engine out. There's a few wiring
harnesses, the usual coolant, subframe, axles ... but most of that you
take out just to take the exhaust off the turbos themselves. Removing the
engine + transmission is only... an extra 2 hours? It just drops out the
bottom all as one tidy piece.
