[s-cars] Installing Torsen diffs and disabling EDL on a 95.5 S6.

[Stott Hare]

I'm with you there Mark.  I miss the 4kq and 5ktqs.  So much so I'm giving
serious consideration to installing an Urq gearbox into my S6A, gaining
lockers, a longer fifth (cruising) gear, and perhaps a little better overall
mileage.

I know it was a totally different generation but my 5KCSTQ with manually
locking center and rear diff with ABS on/off ran circles around my UrS6 in
snow.  Ah the good old daze when the pilot made the decisions.

Well I will say that you guys sure seem to have a different opinion of it
than me.  I have never had any trouble getting up my driveway, etc.  The ESP
makes it no fun to drive in the snow because it is darn good at controlling
the car.  The cutting of the throttle through the ESP is definitely not on
my list of "highs" about the car, but I can always turn it off and it's not
all that bad for the most part.  Annoying on dry pavement is certainly true
if you are pressing the car.  I don't know how it drives in an A3 or A4 but
I can tell you that my 2.7T A6 and the '01 S4 both make great snow cars.  I
have owned these two cars with ESP and EDL it and 4 quattros without either,
and these are certainly as snow worthy as any of the former.

I am uniformly disgusted with the ESP that is on the GTI and A3, which
should be similar, even in FWD form.  The first step taken after
starting the car ON DRY OR WET ROADS is to disable it.  It is so
hyperactive that it even activates backing out of the driveway and,
particularly, when accelerating away from the drive with the wheels
turned.  Utterly ridiculous.  The difference between cornering with and
without it is intrusive annoyance vs. enjoyment.  How they can have it
dialed in so incorrectly on a 'sporty' car is beyond me.  When trying it
out in the wet, I also found it more annoying than helpful.  Can't
imagine how bad it could get in reducing the effectiveness of AWD...

as well as the manual diff lock on my '91cq.  A litmus test is turning into
my driveway- it is very steep and you must approach at a sharp angle to
avoid dragging the nose and tail.  This results in the inner rear wheel
lifting off the ground, and the outer front wheel having minimal traction.
With the '91 the lifted wheel would spin in the air, I'd need to lock the
rear diff to proceed up the driveway.  The '00 did this transparently- just
a bit of ABS chatter.  And performance in snow and ice was right up there
too.

the same as on the '00.  A little ABS chatter but otherwise transparent.  It
doesn't drive sideways in snow as willingly as the B-series cars but I think
that is more due to the wheelbase than the drivetrain.

and ASR (traction control).  The driveway test seems to confuse the
computers and while I do get up the driveway with the usual ABS chatter, it
lurches and shudders.  And worse, the drivetrain behavior becomes very
unpredicable in snow.  I was at Tahoe a few weeks ago when it snowed 5 feet
and charging through snow berms etc. was not at all controlled or
comfortable.  I could feel the ASR (which cuts the throttle) kicking in, ABS
chatter, some burning clutch smell, and no forward movement.  Fortunately,
there's a button to disable all this (except for EDL which cannot be
disabled) at which time it works very much like the '95.5 and '00-
straightline or sideways.  With a new set of Pilot Alpin snows on the car it
was quite unstoppable (given the usual ground clearance constraints of
course)- provided I remembered to hit the ESP disable button.  It also gets
up the driveway with much less drama when
