Not entirely true. It takes a while for the ABS to recognize the
non-working sensor. If you are required to brake before the ABS has kicked
off, you could get a surprise in the form of longer braking distances
accompanied by ABS music.

One of my 90Q's has an improperly adjusted sensor and will not kill the
ABS, as would be expected, no matter how far I drive. I must manually do so
with the dash button. There is no problem driving with the ABS off. It's
trying to remember to push the button to turn it off before the first
attempt to brake after starting or re-starting. Be careful....it is
possible that braking response may not be predictable without all ABS
sensors active and .....with ABS on. Experiment in a safe place with ABS on
BUT as a precaution in normal driving, always push the dash button after
starting because your first stop could be before the ABS kicks off.
