[BiturboS4] help diagnosing two problems

[ Converted text/html to text/plain ]

So, I just bought my (used, 2001, 9k miles) S4 about three weeks ago and I
think I've identitifed a couple of glitches.  When I am coming to a stop, t=
he
engine vibrates a little as if it is stalling and then it recovers just as I
come to a stop.  It happens at all temps and I notice that the tachometer
falls slightly below the idling rpm during this momentary vibration.  I
mentioned it to the dealership when I had it in for 10k service and they sa=
id
it was normal - that the fuel injectors were just falling slightly below
normal idle rpms as they "rebounded" back to the idle levels from when I was
driving under load.  I thought that was weird because I've never had that in
other cars.  Do you guys experience this?

The second thing is a little troubling. As I engage the clutch for 1st gear
from a stop, I feel a sort of slip and bump after the car is moving slightly
and the clutch is about half way out.  The problem is much more apparent wh=
en
the car is cold.  It's almost like the clutch is slipping and then regrabbi=
ng
during the middle of the first gear start-off. It doesn't happen in any oth=
er
gears.  Any ideas?

Thanks, Carter.
