I had a '92 and a '93 9000 (both w/ ABS of course) and neither of them
ever behaved this way. The ABS light should come on at starting and go
off within a few seconds. You should not have to move before the light
goes off. Diagnosing the problem may be tricky until the unit fully
fails. So long as the ABS light does go off eventually I guess I would
just continue to monitor it.

The ABS light tends to stay on during the first journey of the day, then
goes off at the next journey.

Oh, that's not so good then. I'd have it diagnosed first thing in the
morning by leaving it at the mechanic's overnight. Of course you
realize that as soon as it gets to the mechanic's it will stop acting up
until you bring it back home. ;-)

But that has it's positive side... It recently went through MOT, it happened
just as you said :-)

The ABS indicator light on my 1993 9000 CSE comes on when staring first
time in the morning, it sometimes stays on while driving off. However,
this might not happen from the following starts during the day.

This may be more serious but check the sensors first. Measure the
resistance at the sensor connections for 800 to 1400 ohms. The front
sensor connectors are located on either side of the fish tank. The
rear sensor connectors are beneath the rear seat cushion.

Are you sure this is a problem? My '92 900 always did this (about 1
minute for a cold start) in the 5 years I had it, and I just replaced
it with a '91 which does it as well.

The mechanic plugged in some diagnostic display, it showed that one rear
wheel ABS sensor was bad. Had it replaced today.
