ABS Lights

["Tom Brown" <tbrown@xxxxxxxxxxx>]

Chuck:

What year is you oilhead?   BMW has changed their ABS system a couple times 
and uses different brake systems on different models.
More than likely, if it's an 1100, the battery is not strong enough and the 
cold weather is making the starter draw more current.   Low voltage during 
the ABS boot-up cycle on these bikes will cause the fault.   The 95, 96 and 
early '97 bikes were more sensitive to low battery voltage than the later 
1100s.

A New and Separate ABS Issue:

I have an '04 RT that I bought in August of last year.   I had it in last 
spring for brake fluid service.  After that time, the bottom dash indicator 
would stay on about 60% of the time after start-up.   My solution was to 
shut the bike off while rolling, at any speed, with the clutch in, re-start 
the bike, match revs and continue on.   The light always went out.

Until I changed the oil recently.  After doing this, I got on the bike and 
went to a meeting...in a hurry.  I rode quite a long way before I found the 
place and time to safely shut off and restart the bike while rolling.   It 
didn't work.  Tried again, still wouldn't work.   Yesterday, I rode 400 
miles on it and never could get it to reset.   I guess back to the dealer to 
finally complain about service that was done wrong last spring....they'll 
never believe me.
