[s-cars] Does this ring a bell

[Keith Maddock]

A quick way to test if it's ABS related or not would be to disable the ABS via fuse-pull, or locking your center diff (below 15 mph, coasting, hit the diff button).  If you then can make a stop without the vibration, it's the ABS for sure.

Not sure about the Audi/Bosch system, but any of our ABS systems will self-disable and light the ABS lamp if a sensor wire is cut...  (Double detected through a resistance check through the individual sensor circuits, as well as erratic signal detection routines)

I had a similar but more severe problem with my ABS when I had my eibach/bilstein combo installed, one of the ABS sensors wasn't seated all the way.  All it took was shoving the sensor back in.

When they did your brakes, they cut a wire by
accident.  Check the wiring running from the spindle
to the ABS controller.  BTBT  (Been there, broke that)

Does it feel ABS related?

Have you tried pulling out the ABS sensors, cleaning them off, putting a
little lube on them and the pushing them back in?

Just a wild guess.

Hello all,
Thought I might pose this one to the experts:
On my S4, when you com to a stop, on the last few revolutions of the wheel,
there is a vibration that can be felt through the brake pedal. ( it is
pretty
hard to hear it) it does not matter if the clutch is in or out or the brakes
are applied or not. I had thought it was the tires, the car has new tires
and
brakes all around. I'm stumped and look to you O gods of all things quattro
btw: I have a set of 16" Toyo Fz-4 (225/50/16 ZR) in useable condition free
for the taking in Maplewood NJ
