Im about ready to crush this POS unless someone has any greaet
suggestions.  its a 98 2.8 with about 80K on it.  This past summer the
ABS light came on so they took off all the sensors and cleaned the crap
off them. No help. VAG-COM said "unable to communicate with ABS
controller" Ok its shot, fine.  Got the upgraded one and installed it,
bled the system etc. Brakes function but the ABS now kicks in at the
slightest thing. Even on flat dry <<snip>>

I concur with Shawn. On my 95 (probably slightly different), I recently replaced all the
wheel bearings, and while I had all that stuff apart I de-crustified the ABS rings. My ABS
is much crisper now and the nuisance applications of the ABS have gone away. Mine seemed
random. Sometime wet, sometimes dry. Was subtle enough for me to question whether it was
even a problem, but now that I worked on it, it is definitely fixed.

aside 1) After a thorough clean-up, I also coated the ABS rings with "extend". I am not
advocating this, just saying what I did.

aside 2) I had what I thought was a need to get my ABS sensor out in order to replace the
bearing. Long story short: I broke it. The new one was $215. Mommy.
