[s-cars] Re ABS issue

[Tom Green]

It has worked for me, Bob.  BTDT.  My 95 model has pointed me directly  
to the offending wheel when the sensor was not properly seated
through a wheel specific DTC when queried with VAG-COM.  The DTC did  
not seem to stay stored for a long period, so it was helpful at times  
to rotate wheels
with car on a lift, but if I check codes with VAG-COM right after  
triggering the little ABS kick when stopping, the code would be there.
