my cluster looks original - I base that on the dact that it is still the mechanical "rolling wheels" odo.
I have not had the guts to try and get the asr light to come on by provoking slip. Maybe when there is less traffic....

You may have ASD (automatich sperr-diffrential), later
named ETS (electroic traction support). BTW, this is
the part retained when EPS or ASR is turned off, and
therefore may not have a button to be turned off
on your car either.
ASD and ETS is sensing the wheels on the rear
axle to not have the same rotational speed, and
will brake the one going faster. ASR is in addition
also monitoring the front wheels to sense that
both rear wheels spinning (going faster than the
front ones), and then reduce the
trottle speed. Finally, EPS will monitor the
steering wheel angle and calculate a correct turning
radius from that. Via accelrometers, any
deviation from that will cause the brakes to
brake the car into the correct path again;
Oversteer and the outer front wheel will brake.
Understeer and the inner rear wheel will brake.
The first W140 (or correct C140) to have ESP
was the S600C in May 1995.

For the provoke of slip, just come here
to Norway and have a drive in the snow!
I´m glad for my EPS these days...
Today, I drove my car to much on the snowy curb
in a corner, got the tail end swinging out, but
ESP got into action and stabilized the car.
