<Audi> Solved ABS problem

I've been having an intermittent problem w/the ABS on my '90 200tqw.  Every
once in a while, while you are in the process of slowing down and hit 5-10
mph, the ABS would go crazy, cycling very quickly.  It would give you a
heart attack, because you essentially had no brakes and you would blow
right through the red light (or stopped car) you were stopping for.

Well, I fixed it, without spending a thing.  I pulled the ABS sensors, and
they were covered with large amounts of goop and metallic particles about
1/4 inch deep.  Cleaned them off, lubed them back up, and put them back in.
 Presto, no more problem (well, not yet....)

amazed at the crap on the sensors.

BTW, the 'press-in' nature of the ABS sensors strikes me as rather cheesy.
Others I have worked on have been secured with a bolt or something more
secure.  As far as setting the gap is concerned, I just pushed them all the
way in until they bottomed, and pried them out a tiny bit.  They worked
fine with this rather crude procedure.  Bentley was no help with this whole
